Compress

Every tool runs inside your browser. Documents are never sent to a server, so there's nothing to delete afterwards.

Use any tool as often as you like. We don't add our name or logo to your files.

Open a tool, choose your file and download the result. It works on phones as well as computers.

Is LMPure PDF free?

Yes. Every tool on this page is free to use, with no sign-up and no watermark added to your files.

Are my files safe?

These tools run entirely in your browser. Your files are read and processed on your own device and are never uploaded to our servers.

Does it work on mobile?

Yes. Every tool works in Chrome, Safari and other modern browsers on Android and iPhone. Very large files are faster on a computer.

Is there a file size limit?

There's no fixed limit, because nothing is uploaded. The practical limit is your device's memory. Most phones handle files of 100 MB or more.
