Frequently asked questions

My form requires a 20 KB photo and a 20 KB signature.

TargetKB compresses both. Because 20 KB is small, it will shrink the image resolution too — that is expected and normal for these limits.

20 KB seems impossible for my large photo. What do I get?

TargetKB pushes as far as it can (down to a 64px minimum edge). If 20 KB is genuinely unreachable it returns the smallest version it can create and tells you the exact size.

Is it really free with no account?

Yes. No signup, no watermark, no usage limits on the tool. Compression runs entirely in your browser.
