All steps in one go

Merge files, fix the page order, sign, add page numbers and a watermark, then download one finished PDF. No going from tool to tool.

Private by design

Big PDF websites upload your files to their servers. PDF Studio does all the work inside your own browser, so contracts, ID cards and bank papers never leave your device.

Sharp, real PDFs

Pages are copied as they are, not turned into pictures, so text stays sharp, searchable and easy to copy.

Questions people ask

Why do I need an account for PDF Studio?

The account is free and takes seconds with Google. It lets us keep PDF Studio free with no limits and tell you about new PDF tools. Merge, split, rotate, page numbers and watermark are free without an account.

Are my PDFs uploaded?

No. PDF Studio reads and builds your PDFs inside your browser. Your files never reach our server.

Can I undo a change?

Yes. Press Undo or Ctrl + Z for any change until you download. Redo brings it back.

Is there a page or file limit?

No daily limit and no watermark. Each file can be up to 200 MB. Very large PDFs depend on the memory of your phone or computer.

Will the text in my PDF stay sharp?

Yes. Pages are copied as they are, so text stays sharp and can still be selected and searched. Only locked PDFs are saved as images, and we tell you when that happens.

Does it work on phones?

Yes. Press and hold a page to drag it, and tap pages to select them. Signing works with your finger.

Making the same PDFs every week?

We automate invoices, reports, certificates and contracts so your PDFs are made, numbered and sent for you.
