Resize an image to an exact KB size
Every portal sets a different upload limit. Pick the size your form asks for — we compress the photo in your browser and hand you a JPEG that fits, free and with nothing uploaded.

Need to compress a signature instead?
Most exam forms ask for a separate signature file. Resize signature to 100 KB or 10–20 KB signature — both run free in your browser.
How to pick the right size
- Read the form's instruction line — it usually says "photo must be less than X KB".
- Pick that exact size above. If your limit sits between two options, choose the smaller one.
- Check the pixel dimensions too. Some portals reject a file that is the right weight but the wrong shape.
- Upload, download, and attach the result to your form.
