Resize an image to a specific file size

Pick this page when you know the size limit but not the pixel dimensions, like a form that rejects anything over 100KB. Each target below is its own quick tool: upload, and the browser handles the rest.

Which page should I use?

These tools work best when a form, portal, government site, or upload workflow tells you the file must stay under a specific size, such as 50KB or 100KB.

  • Know the size cap? Pick the matching KB target below and let the browser optimize automatically.
  • Need exact width and height first? Use the manual image resizer, then compress afterward.
  • Mainly trying to shrink the file rather than change its dimensions? Any of the targets below will do that.

Compress to an exact KB target

The most common size limits for uploads, forms, and document systems.

Larger 500KB and 1MB targets

These less aggressive targets preserve more detail when the receiving system allows a larger upload.
