JPG, PNG or WEBP — up to 20 at once, everything happens in your browserWhere a 20KB limit usually comes from
Several recruitment and entrance-exam portals in India ask for a signature under 20KB alongside a separate photo limit — it keeps their servers light when they're processing lakhs of applications at once. If your form is rejecting a file for being 'too large', 20KB is one of the more common thresholds to check for.
Because 20KB still allows a bit more detail than 5KB, most passport-style photos compress into this limit without losing too much sharpness, especially if the original photo wasn't enormous to begin with.
❓ Frequently asked questions
What if my file is already under 20KB?
The tool detects this and just gives you the original back — no need to compress an image that already fits.
Does it change the photo's dimensions?
Only if quality reduction alone isn't enough to reach 20KB. In that case it shrinks the pixel size slightly and tries again.
Can I use this for a signature instead of a photo?
Yes — the same tool works for any image file, signatures included.
