A complete PDF workbench in your browser: merge, split, compress, convert, watermark, number, and protect PDF files — with no uploads, accounts, or watermarks.

Every PDF Studio tool runs entirely in your browser — files never leave your device
Processing happens on your device via WebAssembly-grade browser tech. Close the tab and nothing persists.
No daily quotas, no forced sign-in, no stamps on your output. Limits exist only to protect your browser's memory.
Contracts, payslips, medical records — safe to process because they never travel over the network.
Each step runs on the result of the last, so a multi-step cleanup does not mean downloading and re-adding the file between tools.
Input
A 40-page scanned contract that needs its fax cover removed, two pages reordered, a CONFIDENTIAL watermark, and compressionOutput
One 39-page watermarked, compressed PDF, produced without the file leaving the browser at any point.PDF Studio is the hub for all of motifuse's PDF tools. Instead of hunting for a different website for every small task — one to merge, another to compress, a third to rotate — you get sixteen focused tools that share one workflow and one privacy model: your files never leave your device.
That local-first design isn't a marketing line; it changes what the tools are safe for. Because processing happens in your browser (using the same technology PDF viewers use), you can work on employment contracts, bank statements, medical records, and client deliverables without a third-party server ever seeing them. It also removes the classic annoyances of online PDF services: no upload wait, no processing queue, no daily task quota, and no watermark stamped on your output.
Start with the tool that matches your task below, or use the search box. Recently used tools appear at the top on your next visit (stored only in your browser).
Pick the operation you need — merge, split, compress, convert, watermark, number, or protect.
Drop your PDF (or images) into the tool. Files are read locally; nothing is uploaded.
Adjust the operation's settings and preview where available.
Download your result — individually or as a ZIP for multi-file outputs.
Per-file limit is 200 MB and per-job limit is 400 MB — these protect your browser's memory, since processing happens on your device rather than a server. Documents over 2,000 pages are rejected for the same reason. Scanned-PDF text recognition (OCR) and redaction are not yet available.
PDF Studio is motifuse's suite of sixteen browser-based PDF tools covering organizing (merge, split, extract, reorder, delete, rotate), optimizing (compress, metadata), converting (PDF↔JPG/PNG), and customizing (watermark, page numbers, password protection). Every tool processes files locally — nothing is uploaded.
Those services upload your file to their servers for processing and meter free usage. PDF Studio processes everything inside your browser: no upload, no server-side copy of your document, no daily limits, and no watermarks on output.
Once a tool page has loaded, the processing itself needs no network connection — you can disconnect and still merge, split, or compress. The page load itself requires a connection.
Current versions of Chrome, Edge, Firefox, and Safari on desktop and mobile. Very large files work best on desktop browsers, which allow more memory per tab.
