Merge, split and compress PDF files
Combine PDFs into one, pull out the pages you need, or shrink a file — all done locally in your browser, so your documents never leave your device.
How it works
- Pick a mode — merge, split or compress. Then drop your PDFs.
- Reorder pages to merge, or type the ranges you want to split out.
- Download the result. It was built on your device, not a server.
Frequently asked questions
Are my PDF files uploaded to a server?
No. Merging, splitting and compressing all happen in your browser using JavaScript — your PDF files never leave your device, so the tool keeps working even offline once the page has loaded.
Can it really compress a PDF?
It re-saves the PDF with object streams and strips metadata like the title and author, then shows you the exact size change. It cannot recompress images already embedded in the PDF, so a mostly-scanned file barely shrinks — and if the result is not smaller, the tool tells you and hands back the original instead of pretending.
How do I choose which pages to split out?
Type page numbers and ranges like 1-3, 5, 8-10 — each comma-separated part becomes its own PDF, bundled into a ZIP when there is more than one. You can also split every page into a separate PDF in a single click.
Is there a file size or page limit?
There is no artificial limit. Because everything runs on your own machine, the only ceiling is your device's memory — very large PDFs simply take a little longer to process.
