About this tool
Many application forms ask for a passport-style photo or signature between 10 and 20 KB, or simply “under 20 KB”.
A head-and-shoulders photo at 20 KB is typically 300–450 pixels wide and still clearly recognisable.
If the form also gives exact pixel dimensions, use the Signature resizer, which hits both the pixels and the KB limit.
Frequently asked questions
Are my files uploaded to a server?
No. Everything happens inside your browser, on your own device. Your files are never sent anywhere, and the tool keeps working even if you go offline after the page has loaded.
Will the file be exactly 20 KB?
It will be just under 20 KB. Upload forms reject files that are even 1 byte over, so the tool always stays below the limit.
Does it work with iPhone photos?
Yes. HEIC photos from an iPhone are converted and compressed in one step.
Is it free?
Yes, completely free, with no sign-up, no watermark and no daily limit.
