How it works
- Drop the photo or signature the form asks for — JPG, PNG or WebP.
- If the form also gives a width and height in pixels, resize first; otherwise just go ahead.
- Press Compress to 20 KB and check the size shown next to the file before you upload it.
Frequently asked questions
- What fits in 20 KB?
- Comfortably a passport-style photo or a signature. A full-size phone photo is first saved at a lower quality and, if that is still too big, made smaller — to about 300 × 380 pixels for a photo at this target.
- Which forms ask for this size?
- Exam and recruitment forms very often ask for a photo or a signature under 20 KB, sometimes between 10 and 20 KB or 20 and 50 KB.
- How is 20 KB counted?
- The result stays under 20,000 bytes, so it passes whether the form counts a kilobyte as 1,000 or 1,024 bytes.
- Is my picture uploaded?
- No. Everything runs in your browser. The free plan handles 3 images per run, 20 MB each and 5 runs a day.
