Frequently asked questions
Can I compress a passport photo to 20 KB without it looking blurry?
Yes, if you crop it to head and shoulders first. Most of the 20 KB then goes to your face rather than the background, and the tool keeps the highest quality that fits. A full-length photo has to shrink much more.
Can I compress my photo and signature together?
Yes. Add both files and click Compress images; each one is fitted under the limit separately. If your form wants different limits for each, compress one, change the size, then compress the other.
How big will the picture be in pixels?
A typical photo fits in 20 KB at about 240 × 320 pixels, which is plenty for a passport-size photo on a form. Simple images such as signatures can keep more pixels.
Is my image uploaded when I compress it to 20 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 20 KB
20 KB is a common limit for passport-size photos and signatures on exam, job and government application portals. At this size a face photo still looks clear if it is cropped to head and shoulders, which is what these forms ask for anyway.
As a rough guide, a typical photo fits in 20 KB at about 240 × 320 pixels while still looking clean. Pictures with plain backgrounds, such as signatures and documents, can keep more pixels; busy, detailed photos need fewer.
