Fill and Sign

Put text, a date, a check mark or a signature anywhere on any page of a PDF. Draw the signature or drop a PNG, drag or nudge to place it, and save. The original text layer stays searchable.

Good to know

This is a visual signature, not a certificate-based digital signature. Check whether a visual signature is acceptable for your purpose.
Your signature is never stored. It goes away when you close the tab.
Sideways pages are handled, so items land where you placed them.

Your files stay on your machine

This tool runs entirely inside your browser tab. Nothing is uploaded, stored, or sent to a server — close the tab and every trace is gone.

How big a file can it take?

There is no upload, so there is no upload limit — but the work happens in this tab, which means your browser’s memory is the budget. Nothing here will refuse a file for being large; a big enough one simply gets slow and, eventually, reloads the tab. The figures below are rules of thumb on a desktop browser, not enforced caps. On a phone or tablet, expect a good deal less.

One page is drawn at a time, so file size binds: comfortable to about 200 MB.
A signature image is embedded once and reused, so repeating it adds very little.

Password-protected PDFs are declined whatever their size — unlock the file first. If a run does die on a long document, splitting it into volumes and working through them one at a time is the reliable way round it.
