Compress an image to 50 KB
50 KB caps show up on job application systems, university portals, and older CMSes. It's tight but achievable for photos up to roughly 800 pixels without obvious damage.
The compressor opens in target-size mode at 50 KB, binary-searching quality to land the largest result under the cap. The before/after slider shows exactly what the compression costs before you download.

How it works
Select an image; it decodes locally.
Choose an output format and quality, or set a target file size.
Compare original and compressed versions with the wipe slider.
Download — the size you saw is exactly the size you get.
What the tool does
- Quality slider with live re-encode and exact byte counts
- Target-size search that reports honestly when the target is unreachable
- JPEG, WebP, and PNG output
- Wipe-style before/after comparison at matched zoom
- Metadata stripped by default via clean re-encode
How the result is verified
The compressed bytes are re-decoded to confirm the image parses and dimensions match, and the displayed byte size is measured from the actual output blob.
Frequently asked questions
Will 50 KB visibly degrade my photo?
At 800px or smaller, usually barely. The wipe comparison shows the real output against the original, so the judgment is yours rather than a surprise after upload.
Should I use WebP to hit the target more easily?
WebP compresses better, but strict upload forms frequently accept only JPG. Stick with the JPG default unless you know the destination takes WebP.
