PDF Merge & Split — Offline

Merge, reorder, split, rotate, extract, and delete PDF pages entirely offline. Your PDFs never leave your browser.

PDF Merge & Split — Offline lets you combine, split, rotate, and clean up PDFs without uploading anything, anywhere. Every operation runs locally in the extension's own page, using pdf-lib — a pure-JavaScript PDF library that ships entirely inside the extension (no server, no cloud processing). Click the toolbar icon to open the tool in its own tab — not a popup, so an in-progress multi-file merge survives you switching tabs to go find another file. FREE, AND GENUINELY USEFUL - Merge up to 5 PDFs at once, in whatever order you choose. - Reorder pages within a file, or reorder which files feed a merge. - Basic split: break one PDF into two parts at a page boundary. PREMIUM ($5 one-time) - Unlimited merge — no file-count cap. - Page-range extract: pull any set of pages (e.g. "1-3,5") into a new PDF. - Rotate: rotate a page range, or the whole document, by 90/180/270 degrees. - Delete pages: remove any set of pages from a document. - Compression-lite: strips document metadata and re-encodes with object-stream compression. This is NOT image recompression or downsampling — it will not shrink a PDF full of large scanned images the way a dedicated image-recompression tool would; it reduces structural overhead only, and may not shrink (or could even slightly enlarge) a PDF that is already optimized and carries no strippable metadata. - Saved workflows: name and re-apply a page-range/rotation configuration later, without re-typing it — stored only on your device. PRIVATE BY DESIGN This extension never reads the current tab or any web page — it only processes PDF files you explicitly drag in or select. It requests exactly one permission, storage, used only to save your (optional, premium) workflow presets on your own device. This extension collects no data of any kind — no analytics, no tracking, no telemetry. The only network traffic it ever makes is a purchase-verification check with ExtensionPay if you choose to upgrade. No subscription, no account required — pay once, keep the features.
