Fuse-PDF was built out of frustration with PDF tools that require you to upload sensitive documents to unknown servers, create accounts, and deal with aggressive paywalls — just to combine a few files.
We took a different approach: what if every tool ran entirely in your browser? No uploads. No accounts. No subscriptions. Just open the page and get the job done.
Whether you're merging contracts, splitting a large report, compressing a presentation, rotating a scanned document, or watermarking invoices — every single operation happens locally on your device using your CPU and RAM.
Fuse-PDF is powered by pdf-lib for PDF creation and manipulation, pdf.js (Mozilla) for rendering PDF pages to images, and JSZip for packaging multiple outputs. All are open-source libraries that run entirely in browser JavaScript.
All 8 tools will always be free. No watermarks on your output, no file size limits that unlock with payment, no "you've used your 3 free conversions this month" nonsense. No ads, no tracking, no data collection.
We collect nothing. Your files never leave your device. All 8 tools process files entirely within your web browser. No data is ever transmitted to any server.
None. Specifically: no name or email, no account, no file uploads, no cookies for tracking, no analytics, no advertisements.
Fuse-PDF is a client-side web application. Files are read from your local disk into browser RAM, processed using JavaScript, and downloaded back to your device. Nothing is sent over the internet.
