Nine PDF tools.
One free app.
Orb2Bit PDF does the whole job: split, merge, crop, compress, organize and create PDFs, add or remove watermarks, and edit pages with text, images and freehand drawing — all 100% on your device. No uploads. No accounts. No tracking.
The full app — right in your browser
Orb2Bit PDF Web runs the same nine tools as the desktop app — visual page picker, split groups, crop, merge, watermarks (add or remove), compress, page edits with shapes and pen, organize, and create — with a live preview throughout. Nothing to install, and your file is processed on this device and never uploaded anywhere.

Nine tools. One window.
Everything most people ever need to do to a PDF — without a subscription, an upload, or a second app.
View
Open a PDF and read it straight away, with a thumbnail filmstrip to jump between pages. Loads instantly, even on documents with hundreds of pages.
Split
Four ways to cut a file: pick pages on the visual grid (Fast Select grabs a whole range in two clicks), split every N pages, type custom ranges like “1-3, 4-6, 9” for one PDF each, or split at page numbers — “5, 12” gives you 1–5, 6–12 and 13–end. A live preview tells you exactly which files you'll get before you save.
Crop
Drag a box to keep exactly the area you want and trim away margins, scan borders or headers. Apply it to the current page, a selection, or the whole document at once.
Merge
Combine several PDFs into a single document. Add the files, drag them into the order you want, and save — with a preview so you can see the result before you commit.
Watermark — add or remove
Stamp a watermark with full control over position, font, size, opacity, angle, colour and whole-page tiling. Or use the smart eraser: it finds the watermark automatically, even where it crosses your text, and redraws the text underneath.
Compress
Shrink a heavy PDF down to something you can actually email. Pick a quality preset, and the app shows you the original and final size so you know exactly what you traded.
Edit & draw
Add text, drop in images, highlight passages, or cover anything you want hidden. Draw right on the page with box, circle, line and freehand pen tools — each with its own thickness and colour, and a picker for any colour you like. Unicode text works, so Azerbaijani and Cyrillic render properly.
Organize
See every page as a tile and rearrange the document by hand: drag to reorder, rotate any page, delete the ones you don’t need — and restore one you deleted by mistake. Nothing is written until you save.
Create
Build a PDF from scratch out of images, Word documents and text files in any order. A live preview updates as you go — zoom in on any page, and drag an image to place and size it exactly where you want it.
100% offline & private
Your files never leave your computer. No upload, no cloud, no analytics — your documents stay yours.
Lossless where it counts
Splitting, merging and organizing copy your pages exactly — no recompression, no fuzzy text. Compression is opt-in and only happens when you ask for it.
Fast on big files
Hundreds of pages? No problem. The engine is built to stay instant even on large documents.
Three steps.
That’s the whole thing.
No manuals, no setup wizard marathon. Open a PDF and you’re already halfway done.
Get started — it’s freeOpen your PDF
Drag & drop a file onto the window or browse for it. It loads instantly — and stays entirely on your device.
Pick a tool
Nine tools sit in one row of tabs — View, Split, Crop, Merge, Watermark, Compress, Edit, Organize and Create. Click the one you need and the window rearranges itself around it. No menus to hunt through.
Do it & save
Work visually — select pages, drag a crop box, draw on a page, reorder tiles — with a live preview the whole way. When it looks right, save. Your original file is never touched unless you say so.

Seeing a blue warning screen? That’s expected.
Orb2Bit PDF is brand new and built by an independent developer — we haven’t purchased an expensive code-signing certificate yet. Because of that, Microsoft Defender SmartScreen flags the installer the first time anyone runs it. The app itself is safe; here’s exactly what to click to get past it.
Microsoft Defender SmartScreen prevented an unrecognised app from starting.
