Architecture
Your file never leaves the tab.
PDF5 ships its whole PDF engine inside the page itself — not on our server, not in ours or anyone else’s cloud. Open DevTools, watch the Network panel, and the timeline stays empty while you work.

The toolbox
One utility. One dedicated page.
Every tool lives at its own short URL so the search you started with —“merge PDF”,“compress PDF”,“PDF to image” — lands directly on the page that does the job.
- Merge PDFStitch deal packets, closing bundles, and signed agreements into a single file.
- Split PDFCarve one document into many by page range, every N pages, or per bookmark.
- Compress PDFShrink scans and report dumps without dragging them through a stranger’s server.
- PDF to ImageRender pages to PNG or JPG for slide decks, social posts, and quick previews.
- PDF WatermarkStamp DRAFT, CONFIDENTIAL, or your firm logo on every page in one pass.
- Sign PDFDraw your signature on a canvas, pick a page, drag it into place, and download the signed PDF — without uploading anything.
How it works
Three steps. No upload stage.
The flow is the same on every tool. Familiar enough that you can hand it to a colleague without a tutorial.
- STEP 01
Drop your file
Drag-and-drop one PDF or up to one hundred (Pro). The browser opens it locally with the File API.
- STEP 02
Operate in browser
Merge, split, compress, render, or stamp — all inside the open-source PDF-lib, executed on your machine.
- STEP 03
Download the result
When you click download, your browser hands you the finished file straight from memory. Nothing was uploaded to process it.
