About Photo for online form
Online application, exam, and visa portals often reject photos that are too big — limits of 20 KB, 50 KB, 100 KB, or 200 KB are typical. Check the exact limit (and any pixel size or format rule) on the form; this page starts at 50 KB, and you can type the number the form asks for.
The compressor above is already in Target file size mode at 50 KB. It binary-searches JPEG/WebP quality to land just under the limit and, if even low quality is too big, scales the image down step by step. It aims under 50,000 bytes so it passes forms that count 1 KB as either 1,000 or 1,024 bytes.
If the target cannot be reached (for example with PNG, which has no quality setting), the tool says so and shows the smallest result instead of pretending.
Rule of thumb: photo dimensions that usually fit in 50 KB
| JPEG quality | ≈ Pixels | ≈ Size at 4:3 |
|---|---|---|
| High (≈90%) | 0.14 MP | 440 × 330 px |
| Medium (≈75%) | 0.28 MP | 610 × 460 px |
| Low (≈50%) | 0.50 MP | 820 × 610 px |
Estimates for a typical photo. Detailed scenes (foliage, noise) need fewer pixels; flat graphics and documents fit more. The tool measures real file sizes, so trust its result over this table.
How to do it
- 1
Drop one or more images (JPG, PNG, or WebP).
- 2
Keep Target file size at 50 KB, or type a different limit. JPG reaches small targets most easily.
- 3
Check the preview and the result line, then download (several files come as a ZIP).
