Compress an image to 300 KB
A 300 KB budget usually means the destination cares about bulk, not bytes: forums with attachment caps, support-ticket systems, insurance-claim uploads, intranet documents. At this size almost any photo at screen dimensions survives untouched to the eye.
The work happens in your browser. Files never upload — useful when the photo is of your car’s dents or your medical paperwork.

How it works
- Open this page — the compressor is already set for “Compress image to 300 KB”.
- Drop your image into the box, click to browse, or paste it with Ctrl+V.
- The tool re-encodes the image on your own device until it fits the target — nothing is uploaded.
- Check the preview and file size on the result card, then download.
Quality at 300 KB
Photos up to ~2000 px: excellent to visually lossless, depending on content.
The main thing 300 KB cannot do is preserve a 12-megapixel original at full dimensions — but nothing that displays on a screen needs those dimensions. Let the tool scale when it says it must.
Getting the dimensions right
Claim-photo and documentation uploads read best when sharp rather than large: 1600–2000 px at 300 KB beats 4000 px at any quality that fits.
Frequently asked questions
My insurer’s portal takes files “up to 300 KB per photo”. Any tips?
Photograph in good light, then compress here rather than letting the portal’s own uploader mangle the image. Keep the dimensions the tool chooses — legibility of details (scratches, serial numbers, text) is what assessors need.
Why not just screenshot the photo to make it smaller?
Screenshots re-sample your screen, not the image — you lose resolution unpredictably and often gain size. Direct re-encoding keeps maximum quality per byte.
Do I lose the photo’s metadata (date taken, location)?
Yes — the output is a fresh encode without EXIF metadata. If the destination needs the capture date embedded in the file, check whether they read it from EXIF (rare for claim portals, which ask you to type dates instead).
