Free · No sign-up · Your files are processed on your device and never uploaded
Drop it on the page or pick it from your phone or computer.
Pick the options you want - the defaults suit most files.
Ready in seconds. Your file never left your device.
Pages are redrawn in grey at 150 dpi, which looks sharp when printed and often makes colour scans smaller. The text is no longer selectable afterwards.
Text-only PDFs may grow; scans and photo-heavy PDFs usually get smaller.
Combine PDFs into one file in the order you choose. The files are joined on your own device, so nothing is uploaded and there is no queue or watermark.
Separate every page into its own PDF, or take out only the pages you need. Several result files are saved together as one ZIP.
Make a PDF smaller for email and upload limits.
Turn all pages, or only some, the right way up.
