Compress Image to 50 KB
Drop any photo, screenshot or scan and it comes back as a JPEG under 50 KB — at the highest quality that still fits. The whole search runs in your browser.
Where 50 KB comes from
50 KB is the most common of the small ceilings: profile photos, ID uploads and the second page of an application form. It is also the point where the two kinds of image part company — a screenshot, a logo or a scanned page of text will fit at full size, while a photograph taken on a phone will not, and the difference is how much repetition there is in the picture for the encoder to work with.
What it costs to get under 50 KB
Flat images — text, screenshots, line art — usually survive at full resolution around quality 50, though JPEG puts a faint halo around hard black-on-white edges at that setting. Photographs are the harder case: a full-frame phone photo will be scaled to somewhere near a third of its width to fit, and once that has happened the file is for a form field, not for printing. The original on your device is untouched either way.
Why this one is different
Hitting an exact ceiling takes eight to ten trial encodes. A hosted compressor pays for every one of them on every visitor, so it guesses a quality once and hands back whatever that produced. This one runs the search properly, because the processor it runs on is yours.

Questions
How do I compress an image to 50 KB?
Drop your images onto the box above. Each one is re-encoded as a JPEG that lands under 50 KB, using the highest quality that still fits, and the row underneath says what quality that was and whether the image had to be resized. Nothing is uploaded and there is no account.
Should I crop or let it resize?
Crop, if you know what the image is for. Cropping throws away pixels you did not need and spends the whole budget on the ones you did; resizing spreads the loss evenly across a picture that was mostly background.
Does it strip the location data?
Yes. EXIF — including GPS coordinates — is dropped, which both saves bytes at a tight ceiling and means you are not attaching the location of your home to a form. The colour profile is kept, and the rotation is baked into the pixels so nothing arrives sideways.
Do my files get uploaded anywhere?
No. Everything happens in this tab. Your files are never sent to a server, which is why this still works if you disconnect from the network after the page has loaded — and why there is no limit on how many you put through it.
