Frequently asked questions
Is my photo uploaded to your server?
No. Everything happens inside your own browser. Your photo never leaves your phone or computer, and the tool keeps working without internet once the page has loaded.
The form says my file is too small.
PhotoSizeKaro always makes the file at least the minimum KB. With Custom size, set "Min KB" from your notification and the tool meets it.
The form says my file is too large.
PhotoSizeKaro keeps files slightly under the maximum, so they pass whether the website counts 1 KB as 1000 or 1024 bytes. If it still fails, lower "Max KB" by 2–3 in Custom size.
My signature looks grey or has shadows.
Open "Adjust", turn on "Make paper background pure white" and raise Contrast a little. A black gel pen gives the best result.
Does it work on mobile?
Yes. It works in Chrome, Safari and other modern browsers on Android and iPhone.
