PDFGeek: PDF Tools by TechyGeeksHome

PDFGeek puts everyday PDF tools in a tab of your browser, and it never uploads your files.

Merge several PDFs into one. Split out the pages you need. Drag pages into a new order, turn sideways pages the right way up and remove blank ones, with a preview of every page. Crop pages down to the part you need, such as a postage label printed in one corner of an A4 page, and save it at its own size or fitted to 4 x 6 inch label paper, A6 or A4. Turn JPG, PNG and WebP pictures into a PDF on A4, Letter or a page that fits the picture.

Lock a PDF with an AES-256 password that works in every modern reader, or remove a password you know. Shrink files without losing quality. Right-click a PDF link and choose Open in PDFGeek.

Everything runs on your computer. No account, no adverts, no tracking. Free and open source from TechyGeeksHome.
