How we measure

Compatibility

The real reason people convert at all

Nearly every conversion on this page exists because some program refuses some format. When something will not open, the fix is one conversion toward the older format.

Image format compatibility chart 2026: JPG, PNG, WebP, AVIF and HEIC across browsers, Office and email, and image editors: JPG and PNG open everywhere, WebP renders in about 97% of browsers and AVIF in about 95% but both are patchy in Office and editors, HEIC opens for about a fifth of browsers and almost no Windows software
JPG / PNG
The safe destination. Thirty years of software opens them.
WebP
Fine in browsers, still stumbles in Office, older Photoshop and many email clients. The top reason people convert out of a format.
AVIF
Renders almost everywhere on the web, thinner in editors. Serve it with a fallback.
HEIC
The outlier. iPhones shoot it and almost no Windows software opens it. Hence the most-needed conversion family here.
Convert an image under 100 KB with Blinkimg's max file size setting: a PNG converted to JPEG at 98 KB, under the cap in one pass, shown in the result row beneath the Advanced settings

One pass

Convert and hit a size limit in one pass

The signature move the two-tool sites can’t match: set Max file size in Advanced settings and the conversion lands under it in the same pass. The engine binary-searches quality to the best fit, never overshoots, and ships presets at 50/100/200 KB and 1 MB.

“Convert this PNG to JPG under 100 KB for the portal” stops being convert-here-then-compress-there. It works for every output format on this page, and the compress JPG and PNG pages run the same caps when the format already suits.

The four conversion gotchas

Answered before they bite
  • PNG to JPG transparent background: the original on a checkerboard beside the JPG the engine made of it, its transparency flattened onto white

    Transparency into JPG

    JPEG has no alpha, so transparent pixels flatten onto white, matching every mainstream editor. Keep it by exiting to WebP or AVIF instead.

  • Fix a sideways photo, EXIF orientation honoured when converting: the pixels as stored, sideways, beside the upright output the engine produced by honouring the orientation tag

    Sideways photos

    Phone cameras store rotation as EXIF metadata. We honour it before encoding, so the output faces the way the photo was taken.

  • Display P3 to sRGB colour conversion, the profile stripped two ways: two rows of colour swatches, unchanged when the pixels are converted to real sRGB first, muted when the profile is dropped without converting

    Washed-out colour

    Tools that drop a Display-P3 profile without converting the pixels mute the photo. We convert JPG, PNG, WebP and AVIF sources to real sRGB before the strip, so the look survives.

  • Animated GIF conversion keeping one frame: four frames of one animation in a strip with the first highlighted, what a converter that keeps only frame one throws away

    Animated files

    We decline with a clear message rather than silently flattening to frame one. An animation that quietly loses its animation is a data-loss bug.

Unsupported image formats, on purpose: RAW, PSD, AI, SVG and animated GIF, each with the tool that should handle it instead: a RAW developer, its own editor, a PNG export first, a video tool

Scope

What we deliberately
don’t convert

  • Camera RAW (CR2, NEF, ARW…) deserves a real developer, not a web converter's defaults: Lightroom, darktable, or your camera vendor's tool. Export to JPEG there, then optimise here.
  • PSD, AI, SVG are layered and vector sources; rasterising them is a design decision, not a conversion. Export a PNG at the size you need, then convert that.
  • Video-adjacent formats (GIF animations): animation is video's job in 2026. We convert stills honestly instead of flattening your animation to one frame.

Five formats, every direction, done properly, instead of a 500-format list where each pair gets a template. The 16 pairs and 5 hubs below are each their own page with their own measured numbers.

Six things a conversion changes

Why convert images at all?

Because the file, not the picture, is what a page loads, a phone downloads and a program has to open.

  1. 01Page weight

    72.3 KBfrom 1.1 MB PNG

    Pages load faster

    Images are usually the heaviest thing on a page. A screenshot of our pricing page went 1.1 MB PNG → 72.3 KB AVIF; our reference photo 577 KB JPG → 124 KB. Fewer bytes, earlier paint.

  2. 02Ranking

    LCPusually an image

    Core Web Vitals move

    Google measures Largest Contentful Paint, and on most pages the largest element is an image. A smaller hero paints sooner, and that is the number Google ranks with.

  3. 03Mobile data

    10×2 MB vs 200 KB

    Phones on mobile data

    A visitor on 4G waits for every byte and pays for it. A 2 MB photo and a 200 KB one look the same on a phone screen. Only one of them keeps the reader.

  4. 04Cost

    Onceevery load after is cheaper

    Bandwidth and storage bills

    Every byte served costs money at the host or the CDN, and every original kept costs space. Converting once cuts both for as long as the image is online.

  5. 05Compatibility

    HEICApple-only, in practice

    The picture opens at all

    HEIC does not open outside Apple devices. AVIF does not open in old browsers. WebP shows as a broken image in Outlook on Windows. Converting is how a picture reaches the person on the other end.

  6. 06Alpha

    124 KBfrom 4.1 MB PNG

    Transparency at a sane size

    PNG carries transparency losslessly and pays for it in bytes: 4.1 MB for our reference photo saved as PNG. WebP and AVIF carry an alpha channel too, and made it 219 KB and 124 KB.

The formats, in plain words

One question each, answered from what we measured. Every format has its own converter hub with every direction in and out.

  • What is AVIF?

    AVIF is the image format built on the AV1 video codec, and the smallest of the five on all three subjects of our format benchmark: 124 KB for our reference photo, 72 KB for a screenshot of our pricing page, under 1 KB for the flat art. It carries transparency, opens in about 95% of browsers, and is the format to convert to for the web.

    Every AVIF conversion

  • What is WebP?

    WebP is Google's web image format from 2010. It compresses lossy or lossless, carries transparency, and opens in about 97% of browsers. On our camera photo it came out at 329 KB against 606 KB as JPG; on our reference photo it won too, 219 KB against 274 KB. The safe modern choice, and the fallback beside AVIF.

    Every WebP conversion

  • JPG or JPEG: is there a difference?

    None. JPEG is the format, .jpg the three-letter extension from the days when Windows allowed no more, and every program reads both. It is lossy, has no transparency, and opens everywhere: on the web, in email, in print shops and on every phone. Convert to it when the picture has to open anywhere at all.

    Every JPG conversion

  • When is PNG the right choice?

    When nothing may change: screenshots, logos, line art, anything with text, and anything that needs a transparent background kept exactly. PNG is lossless and heavy for photographs. Our reference photo is 4.1 MB as PNG and 124 KB as AVIF at Auto.

    Every PNG conversion

  • What is HEIC?

    HEIC is the container iPhones have saved photos in since 2017, with the picture coded as HEVC video frames. It opens on Apple devices and almost nowhere else: not in most browsers, not on Windows without a codec. Our 343 KB HEIC became a 267 KB JPG for sharing and a 122 KB AVIF for the web.

    Every HEIC conversion

  • Which one should I use?

    AVIF for a website, with WebP as the fallback. JPG for email and anything that has to open everywhere. PNG for print, logos and screenshots, where every pixel has to stay. HEIC is for the iPhone that took it: convert it before you share.

Questions people actually ask

Short answers first. If one of these is your situation, you will find the matching conversion linked above.

What is the best image format for the web in 2026?

AVIF first, WebP fallback. Measured on our reference photo: 123.9 KB as AVIF and 218.9 KB as WebP against a 576.8 KB JPEG source, at ~95% and ~97% browser support respectively. JPG remains the interchange format for everything that is not a browser.

WebP or AVIF: which should I use?

AVIF was smaller on all three subjects of our format benchmark. A screenshot of our pricing page encoded to 72.3 KB as AVIF against 109.6 KB as WebP. The professional answer is both in a picture element: AVIF source first, WebP fallback. Forced to pick one? WebP buys ~2 extra points of reach, AVIF buys fewer bytes.

How do I convert an image without losing quality?

Set quality to 100 and convert to PNG. That pins a truecolour, bit-exact copy of the decoded image, transparency included. At Auto, PNG output is palette-optimised instead: far smaller, and visually clean for graphics. Lossy exits (JPG, WebP, AVIF) trade exactness for bytes. The compare slider on every result is the referee.

Can I convert multiple images at once for free?

Yes: 10 conversions a batch, 30 MB each, mixed input formats in one drop, and one ZIP out with filenames preserved. Free, no signup, no watermark. The free allowance is 300 images a day (100 an hour), counted live beside the tool. That is more anonymous volume than the big server-side tools publish, and it resets daily.

Will converting PNG to JPG remove the transparent background?

It flattens it. JPEG has no alpha channel, so transparent pixels become a colour. Here that colour is white, the fill every mainstream tool uses. Transparency that must survive should exit to WebP or AVIF instead. Both carry full alpha at a fraction of PNG's size.

How do I convert iPhone HEIC photos in bulk?

Drop up to 10 straight off the phone. No plugins, no desktop app, and outputs as JPG, PNG, WebP or AVIF. HEIC is the format Windows and most non-Safari browsers can't open. The HEIC converter hub covers every direction, including the measured size story nobody else publishes.

Which image format has the smallest file size?

AVIF, on all three subjects of our format benchmark, though content decides the margin. Our reference photo came to 123.9 KB as AVIF, 218.9 KB as WebP and 273.9 KB as JPEG. A screenshot of our pricing page came to 72.3 KB against 109.6 KB as WebP. The tool shows your file's real numbers per format.

Is there a file size limit or a daily conversion limit?

Yes, and we publish them plainly, since almost nobody else does: 10 conversions per batch (50 when the format stays the same), 30 MB per file, and 300 free images a day (100 an hour). No queue. Free pages will show ads, and paid tiers stay ad-free. We count the allowance live beside the tool, so you always know where you stand. No surprise walls mid-batch.

Does converting remove EXIF and GPS data?

Yes, by default. Every output ships without EXIF or GPS, so a published photo stops carrying where it was taken. Photographers who need the metadata keep it with one checkbox in Advanced settings. No competitor page states its metadata behaviour at all.

Do I need to install software or create an account?

Neither. You use it in the browser you have, and the work runs on our servers. There is nothing to install, no account required, no email, and the download is direct with no sign-in wall at the end. The same engine also powers an API for automation. An account lifts your limits rather than gating the basics.

Why does my converted image look rotated or washed out?

Neither should happen here. Phone cameras store rotation as EXIF, and we honour it before encoding, so outputs come out upright. Washed-out colour comes from tools that strip a colour profile without converting the pixels. We convert a wide-gamut (Display-P3) JPG, PNG, WebP or AVIF to real sRGB before the default metadata strip, so the photo keeps its exact look.

Can I convert and compress to a target size in one step?

Yes. Set Max file size in Advanced settings and the output format meets it in the same pass, quality-searched and never overshot. "Convert to WebP under 100 KB" is one drop here. Everywhere else it is two tools and two uploads.

How do I convert an image to JPG or PNG?

Drop the image on the tool, pick JPEG or PNG in the output row, and download the result. Pick JPEG for photos: it opens everywhere and stays small. Pick PNG for screenshots, logos and anything transparent, since JPG flattens transparency onto white. Up to 10 images go in one drop and come back as one ZIP.

How do I convert an image to WebP?

Drop the image on the tool, pick WEBP in the output row, and download the result. Up to 10 images go in one drop and come back as one ZIP. Set Max file size in Advanced settings first if the WebP has to land under a limit, and the same pass does both.

Should I convert every image on my site to WebP or AVIF?

Photos, yes: that is where the bytes are. Our reference photo went from a 576.8 KB JPEG to 123.9 KB as AVIF. Serve AVIF first and WebP as the fallback in a picture element. Leave icons and logos as SVG, and keep a JPG or PNG for email, where WebP does not render everywhere.

Does converting PNG to JPG lower the quality?

Slightly, and only once. JPG is lossy, so fine detail softens a little and hard edges can ring. For photographs the trade is invisible at Auto quality, and the compare slider on every result lets you check. For screenshots, text and line art keep PNG, or convert to WebP or AVIF, which hold edges better than JPG.

Which image file types support transparency?

PNG, WebP, AVIF and HEIC carry an alpha channel; JPG does not. Converting a transparent image to JPG flattens the transparent pixels onto white. To keep transparency and lose the bytes, convert PNG to WebP or AVIF instead.

JPG or JPEG: is there a difference?

No. JPEG is the format and .jpg is the three-letter extension from the days when Windows allowed no more. Every program opens both, and converting between them changes nothing but the name.

What is the largest image I can convert?

30 MB per file on the free tool, more on the paid plans, and 100 megapixels per image at every tier, since pixels rather than bytes are what an encode costs. A 100 megapixel JPG is around 30 MB and converts; the same picture as an uncompressed PNG runs to hundreds of megabytes and needs a paid plan.

Can I convert images to a PDF?

Yes. The image to PDF page takes up to 50 images in one drop, compresses each one, and combines them into a single PDF in order. WebP, AVIF and HEIC pages become JPEG, so up to 10 of those fit in a run. One page per image, and the download is direct.

Is it safe to upload my photos to an online converter?

Ours does not hold on to them: we process and wipe files automatically, and we keep nothing, never archive, never train on or reuse your images. We strip metadata from outputs by default. No account means there is no profile to attach files to in the first place.
