Common Questions About These PDF Tools

Is it safe to combine, sign, or edit a PDF here?

Yes — every tool on this page runs entirely in your own browser. Your PDF is never uploaded to a server, so nothing about the file ever leaves your device, even for tasks like compressing or combining multiple files.

Do I need to create an account to use these PDF tools?

No. Every tool here — combine, split, sign, compress, and the rest — works immediately with no sign-up, no email, and no login required.

Can I sign a PDF online without printing it first?

Yes — the Sign PDF tool lets you draw or type a signature and place it directly onto the document, with no printing, scanning, or extra software needed.

Can I password protect a PDF for free?

Yes — the Password Protect tool encrypts your PDF with a password of your choice, at no cost, with no limit on how many times you use it.

Is there a limit on file size or how many times I can use these tools?

No hard limit — since everything processes locally in your browser rather than on a server, there's no daily cap or file-count restriction. Very large files may simply take longer depending on your device's own processing power.
