PDF Bookmarks is a free suite of 30 online PDF tools: merge, split, compress and convert PDFs (PNG/JPG to PDF, PDF to Word), generate a table of contents, add bookmarks, and OCR scanned PDFs into searchable text. It is built for anyone who handles documents - students, office workers, freelancers - who wants the job done without uploading sensitive files to a stranger server. Everything runs locally in the browser; files never leave the device. Free, no watermarks, no sign-up.
I kept needing to merge PDFs for everyday paperwork, and every tool I found wanted me to upload the files first. Contracts and IDs on some server I do not control felt wrong, so I built the toolbox I wanted: the same jobs, done entirely on my own machine.
