Compress an image to under 50KB
“File exceeds 50KB” is the most common reason an upload fails. Pick your target size and this browser fits the file under the limit — nothing is uploaded.
Compress images runs inside this browser. Your file data is never sent to a server. Basic network requests for loading the page and ads may still occur.

How people use it
- Scanned PDF pages exported as images often blow past the ‘50KB’ limit — lowering resolution fixes it.
- Phone photos are usually 3–8 MB, so almost every portal rejects them until they are compressed to 50KB.
- When several files share one attachment limit, compressing each to 50KB keeps the whole set under the cap.

Frequently asked questions
Will the image look bad?
Quality and resolution are only reduced as far as needed to keep text readable. Scanned documents do far better than photos.
Is coming in under 50KB a problem?
No. Upload forms check the maximum, so finishing slightly under the target is the safe side to land on.
Is my file uploaded?
No. Compression happens on a canvas in your browser and the file data never leaves your device.
