The short answer
Why Blinkimg is the best compressjpeg.com alternative
compressjpeg.com does one job well: JPEG in, MozJPEG, JPEG out, in your browser. Blinkimg keeps the same encoder and takes the jobs around it: bigger batches, other formats, a size you set.
01Photos per batch
50compressjpeg.com: 20
A whole folder in one round
Fifty photos are one batch here and three rounds there: 20, 20 and 10.
02Formats in
5compressjpeg.com: JPG only
HEIC and PNG welcome
iPhone HEIC, PNG screenshots, WebP and AVIF go into the same drop as your JPGs.
03Exact size target

One pass to 100 KB
Type the number once. Our 576.8 KB JPEG came back at 99.7 KB under 100 KB.
04Formats out

AVIF when the web wants it
Our test photo measured 123.9 KB as AVIF against 273.9 KB as JPEG.
05Largest file

What compressjpeg.com does well, and where it stops
compressjpeg.com is fast, free and private by design. Its limits are about scope: one format, one size of batch, no target.
What compressjpeg.com does well
✓
Nothing leaves your device

A slider on each photo
After a first pass at its optimal settings, tap any thumbnail to set that photo’s quality by eye.
✓

Where compressjpeg.com stops
✕
20 photos a batch
A folder of 50 photos takes three rounds of selecting, compressing and saving.
✕
JPEG in, JPEG out
PNG and GIF go to sister sites. HEIC, WebP and AVIF have no home, and nothing converts to AVIF.
✕
No size target
A form’s 100 KB limit means lowering the slider, checking the size and trying again.
✕
No resize, crop or metadata option
Its pages state nothing about resizing, EXIF or GPS; metadata removal is a sister site.
✕
No named operator
Its terms name no company, address or contact, and give no date for the last update.

What a JPEG compressor can do to one photo
Every figure is a file our engine produced with MozJPEG. compressjpeg.com publishes typical results but no files, so the fair test is the same photo through both.

Tip 1
Keep the original
Compress from the original once per destination. Re-saving a compressed JPEG at a new quality adds damage.
Tip 2
Resize when far over
A 4000-pixel photo for a 100 KB form keeps more detail when the pixels shrink first.
Tip 3
Judge at 100%
Compare both results at full size. If you cannot see a difference, keep the smaller file.
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.

compressjpeg.com's facts come from its own pages; ours are the limits the tool enforces and the files the engine produced.
Q:What is the best compressjpeg.com alternative?
For more than 20 photos, iPhone HEIC files or a hard size limit, Blinkimg: 50 images a batch, five formats in, and a target in KB that is never exceeded, free with no signup. If files must stay on your device, stay with compressjpeg.com or try Squoosh; both run in the browser.
Q:Is compressjpeg.com safe to use?
Its terms say your files never leave your device: compression runs in your browser through WebAssembly, and the site cannot see your images. The same terms say Google uses cookies on the site for ad personalization and measurement, and they name no company, address or contact behind the service.
Q:Does compressjpeg.com upload my photos?
No, by its own terms: all processing is performed locally in your browser, and no server-side processing is involved. That is a real privacy edge over Blinkimg, which uploads each file to its servers, processes it there and deletes it within 24 hours.
Q:How many photos can compressjpeg.com compress at once?
Up to 20 JPGs, by its own page, and only files ending in .jpg or .jpeg. A folder of 50 photos takes three rounds there. Blinkimg takes 50 images a batch at 30 MB each, and JPG, PNG, WebP, AVIF and HEIC can share one batch.
Q:Does compressjpeg.com have a file size limit?
Its home page and terms state none. Because it compresses in your browser, a very large photo depends on your device's memory rather than a server cap. Blinkimg takes 30 MB a file on Free, 90 MB on Pro and 1 GB on Pro Max.
Q:Can compressjpeg.com compress PNG, WebP or HEIC files?
Not on that site: its file picker takes JPEG only. PNG and GIF have sister sites, compresspng.com and compressgif.com, and none of the tools it links reads WebP, AVIF or HEIC. Blinkimg takes all five formats in one drop and writes JPG, PNG, WebP or AVIF.
Q:Is "Compress JPEG & PNG images" the same as compressjpeg.com?
No. "Compress JPEG & PNG images" was the name of TinyPNG’s WordPress plugin, which runs on TinyPNG’s servers. compressjpeg.com is a separate website that compresses in your browser. Several look-alike domains also use the name, so check the address before you drop a file.
Q:How do I reduce the MB size of a JPEG file?
Drop it into an image compressor and let Auto pick the quality, or type a target such as 1 MB. If it is still too big, lower the pixels too. Blinkimg brought an 1920 × 1280 JPEG from 576.8 KB to 273.9 KB on Auto, and caps it at any size you type.
Q:How do I compress a photo that is too large to upload?
Find the limit the site states, type it into Max file size, and drop the photo. The engine lowers quality first, then pixels, until the file fits, and never returns one over the number. If the site also names pixels, set Max resolution in the same run.
Q:Can JPEG files be compressed without losing quality?
Not much. JPEG is a lossy format, so real savings come from a slightly lower quality that you cannot see. Stripping metadata and better encoding, which MozJPEG does, save a little more without touching the pixels. For true lossless work, keep a PNG or use a lossless desktop tool.
Q:How do I compress a JPEG to under 100 KB?
Set Max file size to 100 KB in Blinkimg and drop the photo. Our 576.8 KB reference JPEG came back at 99.7 KB in one pass. On a tool with a quality slider, such as compressjpeg.com, you lower the quality, check the size and try again until it fits.
Q:Why is my compressed JPEG bigger than the original?
The original was already compressed harder than the setting you chose, so re-encoding at a higher quality added bytes. Blinkimg checks for this: when a re-encode would come out larger, it returns your original file untouched. On other tools, lower the quality or keep the original.
Q:Do compressjpeg.com and Blinkimg both use MozJPEG?
Yes. compressjpeg.com names MozJPEG on its page, and our engine writes every JPEG with MozJPEG too. So the encoder is not the difference; what surrounds it is. Auto picks a quality per photo, a KB target holds a size, and the same run can write AVIF, 55% smaller than our JPEG on our test photo.
Q:Does Blinkimg remove EXIF and GPS data from photos?
Yes, by default. Camera details and the GPS position a phone stored do not travel into the result, and the photo’s rotation is applied first so nothing turns sideways. Tick Keep EXIF metadata to keep them. compressjpeg.com states nothing about metadata and sends removal to exifremover.com.
Q:Why believe a comparison Blinkimg wrote?
Because you can check each line. Every compressjpeg.com fact here is quoted from its home page and its terms, read on September 29, 2026, and linked in the sources. Where it states nothing, such as a size limit, the page says so. Where it beats us, on privacy, the page says that first.
