Local PDF Studio — Merge, Split & Organize

Merge, split, rotate and reorder PDF pages. Everything runs on your device — your files are never uploaded.

Local PDF Studio edits PDFs without sending them anywhere. Most online PDF tools ask you to upload your file to their servers. For a holiday photo that hardly matters. For a signed contract, a payslip, a medical letter or a client document, it does. Local PDF Studio does the same work without the upload: every page is processed inside your own browser, and your files never touch a network connection. WHAT YOU CAN DO — FREE • Merge — drop in several PDFs and combine them into one • Save a selection — pick any pages and export just those as one PDF • Split — save each selected page as its own file • Reorder — drag pages into the order you want • Rotate — fix sideways scans, one page or many at once • Delete — drop the pages you don't need, and undo it if you change your mind • Images — drop in JPG or PNG files and they become pages like any other, sized to fit A4, Letter, or left at their own dimensions PRO — one payment, no subscription • Watermark — stamp text diagonally across every page • Page numbers — "1", "1 / 12" or "Page 1 of 12", bottom left, centre or right, starting at any number • Header — a line of text across the top of every page: a client name, a document title, a draft date • Logo — put your own PNG or JPG in the corner of every page • Export as PNG — save pages as high-resolution images, decorations included • Remove metadata — strip the author name, software and timestamps that PDFs quietly carry with them BUILT FOR PRIVACY • No uploads. No servers. No accounts. • No tracking, no analytics, no advertising. • Works offline — turn off your Wi-Fi and everything still works. • The only network request the extension ever makes is a one-time check of a Pro licence key. No document, and nothing derived from a document, is sent. WHO IT'S FOR Anyone who handles documents they would rather not upload to a stranger's server: lawyers, accountants, clinicians, HR teams, freelancers sending invoices, and anyone whose employer forbids third-party file uploads. Open source libraries used: pdf-lib and PDF.js, both bundled locally.
