Questions

Are my files uploaded?

No. pdfSofo runs inside your browser, so your files are read and combined on your own device. Nothing is sent to a server.

Can I mix PDFs and photos?

Yes. JPG and PNG pictures become pages, sized to match your PDF pages or A4/Letter.

Is there a file size or page limit?

No artificial limits. Very large files depend only on your device's memory.

Do I need an account?

No account, no email, no sign-up. Open the page and start.
