Frequently asked questions
Is 30 KB enough for a clear face photo?
Yes. A typical photo keeps about 300 × 400 pixels at 30 KB, enough for a sharp head-and-shoulders picture on a form or profile.
Why is my file 29 KB and not exactly 30 KB?
The tool always stays below the limit, never above it. Forms differ on whether 1 KB means 1,000 or 1,024 bytes, so it uses the stricter count and your file passes either way.
Can I compress a PNG to 30 KB?
Yes. PNG is a lossless format and cannot be squeezed to a set size, so PNG files are saved as JPG, which every upload form accepts. Transparent areas become white.
Is my image uploaded when I compress it to 30 KB?
No. The compression runs in your browser, so your photo never leaves your device. That also makes it quick: there is nothing to upload or download from a server.
What fits in 30 KB
30 KB gives a passport-style photo noticeably more detail than 20 KB. Some application portals use it as the photo limit while asking for a smaller signature, and it is a good size for small profile pictures.
As a rough guide, a typical photo fits in 30 KB at about 300 × 400 pixels while still looking clean. Pictures with plain backgrounds, such as signatures and documents, can keep more pixels; busy, detailed photos need fewer.
