Common questions

How does Docmend get a photo under 20 KB?

It lowers the JPG quality step by step until the file fits, and only makes the picture smaller in pixels if it still doesn’t fit. You get the sharpest version that is under the limit.

My form also has a minimum size. What do I do?

Use Exam photo and signature: pick the form and Docmend keeps the file between its minimum and maximum KB at the exact pixel size.

Will a 20 KB photo still be clear?

For a passport-style photo or a signature at the size forms ask for, yes. A big holiday photo has to be made smaller in pixels to fit in 20 KB.

Are my photos uploaded?

No. Docmend works on the picture inside your browser, so it never leaves your phone or computer.
