PDFin

Compress, merge, and convert PDFs,
without uploading

Every tool runs on your phone or laptop. ID cards, diplomas, and payslips are not sent to anyone’s server, ours included.

Start

Files are processed on this device and never uploaded.

What do you need to do?

Every tool works on the same file in turn: merge first, add a watermark, then shrink it, without picking the file again.

The size a portal asks for

Type the range, such as 80 KB to 1 MB. Files that are too big are made smaller, and files that are too small are made bigger up to the floor, because portals turn those away too.

Your ID card stays on your phone

Other PDF sites upload your file to their server first. Here the browser on your own device does the work, and a watermark such as "For the application at … only" keeps a copy of your ID card from being used for anything else.

Pick once, keep going

Merge photos of your ID, family card, and diploma into one PDF, watermark it, then bring it under 1 MB. Each step works on the result of the last, with no upload in between.

Try it with the internet off

Once this page has opened, every tool keeps working in airplane mode. It is the simplest proof that your files go nowhere.
