Each of these opens the relevant tool with the settings already filled in for that job, so there is nothing to configure before you start.

How these differ from most online PDF tools

The usual arrangement is an upload, a queue on somebody else’s server and a promise to delete the file within half an hour. These tools never make that copy: the PDF is read, changed and written by the browser tab you are already looking at, which is why they keep working on a bad connection and why there is nothing to sign up for.

One honest limit follows from that. Compressing a PDF hard means re-rendering its pages as images, so the text in the compressed copy can no longer be selected or searched. Every tool that does it says so before you download, and the compressor also offers a lossless repack that keeps the text. What none of them will do is hand back a file larger than the one you started with: if no route beats your original, the original is what you get.

How browser-based PDF tools work — what a browser can and cannot do to a PDF, and where the limits come from.

Questions about these PDF tools

Are these PDF tools really free, with no watermark?

Yes. There is no account, no daily limit, no paid tier and nothing stamped on the output. The file you download is the file you made. These exist because the site already had the reader’s browser doing hard work, and a PDF utility costs nothing more to run when the work happens on your device rather than ours.

Do I have to upload my PDF anywhere?

No, and this is the one thing that makes the section worth using. Every tool here reads, changes and writes the file inside the browser tab you already have open. Nothing is transmitted, so there is no queue, no thirty-minute deletion promise to trust, and no copy of your document on a server that could be breached.

Is there a file size limit?

Not one we impose. The practical ceiling is your own device: everything happens in the tab, so a very large file is limited by available memory rather than by a plan. A desktop browser handles a few hundred megabytes comfortably; a phone will struggle sooner.

Do these work on a phone?

Yes. The tools are the same on a phone as on a desktop, and the file comes from wherever your phone keeps files. Very large documents and OCR are slower, because the work is being done by the phone rather than by a server.

Can I use them offline?

Once the page has loaded, largely yes — you can turn the network off and the tool still works, because the work was never happening anywhere else. The two exceptions download something the first time you use them: OCR fetches its recognition model, and the page renderer fetches its worker.
