Questions

Is PDF Studio really free?

Yes. Every PDF tool here is free with no account, and there is no page or file limit beyond what your device can handle.

Is my PDF uploaded?

No. Your file is opened and changed in your browser, so it never leaves your device.

Can I do several things to one file?

Yes. Rotate, reorder, delete and extract pages on this board, then pick merge, compress, sign or any other tool above. The file you are working on opens there without a new upload.

Can I combine pages from different PDFs?

Yes. Press Add file to put another PDF's pages on the board, drag them where you want, then save one PDF.

What if my PDF has a password?

Files protected with a password cannot be opened. Remove the password in the program that made the file, save a copy, and try again.

Need a website or app built?

We build business websites in 7 days and web apps in weeks, for a fixed price. Then we automate the busywork around them.

About the PDF Studio

PDF Studio is a free set of PDF tools that runs in your browser: merge, split, compress, sign, rotate, redact, convert and edit. Your file is opened on your own device, so nothing is uploaded and you do not need an account.

When to use it

Prepare a contract: merge the pages, sign it and add page numbers in one sitting.
Send a scan by email: compress it, rotate the sideways pages and delete the blank ones.
Share a report safely: redact private details and add a CONFIDENTIAL watermark.
Turn a PDF into images or text for a slide deck, a website or an AI chat.

Tips for a better result

Open the file once and move between tools from the menu. The same file stays loaded.
Keep your original. Every tool saves a new copy, so you can always go back.
For very large files, close other browser tabs first. The work happens in your device's memory.

Why a browser PDF tool is safer

Most tools here run inside your browser. The file is opened on your own device and the result is made there too, so it is never uploaded to our servers. That makes them safe for contracts, IDs, payslips and client files, and they keep working on slow connections because nothing large is sent. You also do not need to install software or create an account. Every tool saves a new copy, so your original file stays exactly as it was.
