Questions and answers
Can I use Arabic, Urdu or Hindi text?
Yes. The watermark is drawn with your device's fonts, so any language your device can display works.
Can the watermark be removed?
It's part of the page, so it can't simply be deleted. Someone with editing software could still cover it, so it's a deterrent rather than a lock.
Are my files uploaded to a server?
No. Every tool runs inside your own browser, so your files stay on your device. The only exceptions are when you choose “Email” or “QR code”: then the finished file is sent to our server so it can be emailed or downloaded by link, and it's deleted automatically.
Is it really free?
Yes. PDFSorted is free to use with no sign-up and no watermark. The site is supported by ads.
Does it work on my phone?
Yes. It works in any modern browser on Android, iPhone, Windows, Mac and Linux. On phones you can also use Share to send the file straight to WhatsApp, Gmail or another app.
How does sharing with a QR code work?
After your file is ready, press “QR code”. We create a private download link and a QR code. Anyone who scans it can download the file for 24 hours; after that the file is deleted from our server.
Can I protect my file with a password?
Yes. Tick “Protect with a password” before you press the button. PDFs are locked with AES-256 encryption and ask for the password when opened in any PDF reader. Images are packed into a password-protected ZIP. The password never leaves your device, so keep it safe; it can't be recovered.
