A WebP converter turns a WebP into JPG or PNG when something refuses to open it, or your images into WebP to lighten a website. Both directions, up to 10 files at once. Part of the image converter.

"I have WebP files" vs "I want WebP files": say which
The two populations who type "webp converter" want opposite things. Have WebP, can't use it: images saved from websites that Office, an older Photoshop or a marketplace uploader rejects. Convert out: WebP to JPG for sharing or WebP to PNG for editing. Want WebP: site owners chasing smaller pages. Convert in: JPG to WebP or PNG to WebP. The same tool above does both, with opposite defaults, and each pair has its own page below.

the web migration
One engine, both directions. WebP-out rows use our reference WebP; WebP-in rows use the reference JPEG.
Every byte count is the size of the actual file our engine produced from the named source, the same bytes you would download, not an estimate. The reference photo is one of our own photographs, an iguana on a branch, and the camera photo is a real one too. Drop your own file into the tool above to rerun any of them. How we measure names the sources and the settings.
The WebP format in brief
An image format Google published in 2010 for the web, smaller than JPG on the real photos we measured (our camera photo by 45.7% at each format’s default), with transparency like PNG, in lossy and lossless modes, rendered by about 97% of browsers. The WebP file format is why a picture saved from a website so often arrives as .webp and why an older Photoshop, a marketplace uploader or a print shop then refuses it. Nothing is wrong with the file; the program is older than the format. Converting it out takes one drop above. Why a download arrives as WebP, measured, and how to open one on every device, is in what is a WebP file.
Who still can't read WebP in 2026: the real reason people convert out
Browsers were solved years ago (~97% decode WebP). The holdouts are everything else: Photoshop before 2022 (needed a plugin), Microsoft Office (inserting WebP into Word/PowerPoint remains a coin flip by version), many email clients (attachments render as question marks), Discord and marketplaces (uploads accepted inconsistently), and a long tail of photo frames, kiosks and older phones. That list, not quality, is why WebP-to-JPG is one of the most-run conversions on the web. It is also why "just use WebP everywhere" is only true inside a browser tab.
The q80 knee: one number that saves most mistakes
WebP quality behaves like a curve with a knee at ~80. Below it, photographic detail starts visibly degrading. Above it, file size climbs steeply for differences you cannot see. Two practical rules fall out. First, don’t carry JPEG quality numbers over: each format’s scale is its own, and WebP at quality 90 “to be safe” measured 416.5 KB from our 576.8 KB reference JPG, almost the size you started with. Second, let Auto pick within 75–85 per image and overrule it only after looking at the compare slider at 100%. Graphics and flat art are the exception. They belong in lossless mode, where the question disappears.
When to skip the WebP converter
The file only lives in browsers?
Keep it WebP. Converting out adds bytes and costs a generation for zero compatibility gain.
Chasing minimum bytes for the web?
Go past WebP to AVIF: smaller still, ~95% support, and the pair page has the fallback snippet.
It is animated?
Converting to stills loses the animation, so we decline rather than flatten. Keep it, or use video.
All WebP conversions
Every route in and out runs on the same engine and the same rules. Each card is its own page.
Short answers specific to this page. The tool above settles most of them in a second.
Q:What does a WebP converter actually do, and in which direction?
Both directions, and the direction matters. "I have WebP files that won't open" → convert OUT to JPG or PNG. "I want WebP files for my website" → convert IN from JPG or PNG. Our tool does either. Start from the problem you have and pick the matching exit.
Q:Why won't my WebP file open?
Because software outside the browser lags the web. Photoshop needed a plugin before 2022, Office and many email clients still shrug, and older phones and photo frames refuse. Every browser has decoded WebP for years. The gap is desktop apps, and converting to JPG or PNG closes it.
Q:Which should I convert WebP to: JPG or PNG?
JPG for sharing photos (our 611.2 KB reference → 271 KB on Auto). PNG for editing or transparency (978.4 KB on Auto, 2835.2 KB with every pixel at quality 100). JPG opens absolutely everywhere and is smaller. PNG keeps the alpha channel, and at quality 100 every pixel. Sharing → JPG, editing → PNG.
Q:How much smaller is WebP than JPG or PNG?
Smaller on every photo we measured, by a margin that depends on the picture. At each format's default, our camera photo came out 45.7% smaller as a WebP than as a JPG, a real iPhone photo 20.4% smaller and our reference photo 20.1% smaller. Against a photographic PNG the gap is far wider: 4096.3 KB became a 218.9 KB WebP.
Q:What quality setting should I use for WebP?
Quality 80 is the knee of the curve. Below it, artefacts creep in. Above it, bytes pile up for invisible gains (WebP q90 can land near the source JPEG's size). Auto stays in the 75–85 sweet spot per image. Don't transfer JPEG quality numbers to WebP. Transfer the look.
Q:Does WebP support transparency and animation?
Both. WebP carries full alpha in lossy and lossless modes (a transparent logo converts intact, checkerboard-verifiable) and animation as the modern GIF replacement. We handle animated files honestly: we decline them with a message rather than silently flattening them to one frame.
Q:Lossy or lossless WebP?
Lossy for photographs and screenshots: huge savings, invisible cost at sensible settings. That is what this converter writes. Lossless WebP suits flat art and graphics where every pixel is deliberate; we do not write it yet, so keep that art as a PNG at quality 100. The compare slider lets you judge with evidence instead of guesswork.
Q:How many files can I convert at once?
10 conversions a batch, 30 MB each, one ZIP with filenames preserved. A WebP that stays WebP compresses 50 at a time. It is free, with no signup, no watermark, and a 300-image daily allowance. We publish these numbers because most converters make you discover their walls by hitting them.
Q:Should I use WebP or AVIF in 2026?
AVIF is smaller (our 611.2 KB reference WebP re-encoded to 123.9 KB AVIF) at ~95% support to WebP's ~97%. The professional answer is both via a picture element: AVIF first, WebP fallback. Converting to only one? WebP for maximum reach, AVIF for minimum bytes.
Q:Can I keep the output under a size limit?
Yes. Max file size sets a hard cap, met by quality search and never overshot, in either direction: WebP under 100 KB for a CMS, or JPG under 50 KB for a form. Converter and compressor in one pass is the feature this SERP doesn't have.
Q:What happens to my files in the WebP converter?
We keep nothing. We process your files and wipe them automatically, never archive them, never use them for anything else. We strip metadata from outputs by default, and no account is required.
