Free PDF tools that never upload your files

14 tools for merging, splitting, rotating, watermarking and converting PDFs. Each one runs entirely inside your browser — no account, no upload, no watermark.

Organize

Reorder, split, merge and prune the pages of a document.

Convert

Move between PDF and other formats without losing quality.

Edit

Stamp, number and mark up pages that are already final.

Security

Inspect and remove the information a PDF carries about you.

Your files stay on your device

Most online PDF tools upload your document to a server, process it there and promise to delete it later. These tools skip that step entirely, so there is no copy to leak and nothing to trust us about.

No account, no limits

There is no sign-up form, no daily quota and no watermark stamped on the output. The file you download is the file you made.

Fast because nothing travels

A 40 MB document would take a minute to upload and another to download. Here the work starts the moment you drop the file in, and finishes in seconds.

How browser-based PDF editing works

Modern browsers can run compiled code at near-native speed through WebAssembly. These tools use that to load a PDF parser directly into the page, so operations a desktop application would perform — copying pages between documents, rewriting the page tree, drawing text onto a page — happen locally instead of on a rented server.

The trade-off is memory: your browser has to hold the whole document. That is comfortable up to about 100 MB on a laptop and noticeably less on a phone. For documents beyond that, a desktop application is still the better choice.

Frequently asked questions

Are my PDF files uploaded to a server?
No. Every tool runs inside your browser using WebAssembly. Your files never leave your device, there is no upload wait, and there is nothing for us to store or delete.
Do I need to create an account?
No account, no email, no sign-up. Open a tool, drop in a file, get the result.
Is there a file size limit?
The limit is your device memory rather than a server quota. Around 100 MB works comfortably on a desktop; phones handle less because mobile browsers get a much smaller memory budget.
Are the files watermarked or limited?
No watermarks, no page limits, no daily caps. The tools behave the same whether you use them once or a hundred times.
