Common questions
Why compress to 30 KB?+
A 30 KB cap is common on exam and government forms for photos and signatures — between the 20 KB and 50 KB limits you'll also see. This gets you under it in one click.
Will a photo still be usable at 30 KB?+
For passport-style photos and signatures, yes — they compress well. For a busy colour photo we also gently reduce the dimensions so it still fits while staying usable.
Is my image uploaded anywhere?+
No. This runs entirely in your browser using your device's own processor — your image never leaves your computer or phone.
What if it can't reach 30 KB?+
For large or detailed images we reduce the dimensions too. If it still can't fit while staying usable, we give you the smallest version and tell you — never a broken file.
Which formats work?+
JPG, PNG and WebP. The result is a JPG (or WebP) since those compress to a precise size.
