Five essential PDF tools that run entirely in your browser. Your files never leave your device — no server, no account, no subscription.

1. PDF Merger — Combine Files Without an Upload
PDF Merger lets you drag in multiple PDF files and combine them into a single document. Reorder pages before merging, then download the result — all processed by pdf-lib in your browser tab.
Who it’s for: Remote teams stitching together client reports, students assembling lecture notes, freelancers bundling project deliverables.
Why it’s different: Most “free” PDF mergers cap you at 2 or 3 files and require you to create an account for anything beyond that. There are no file limits here.
2. PDF Splitter — Extract Exactly the Pages You Need
PDF Splitter lets you pull out a page range or cherry-pick individual pages from any PDF. The source file is read entirely in memory — nothing is copied to a server.
Who it’s for: Lawyers extracting specific clauses from contracts, academics pulling a single chapter from a textbook, anyone who needs to share part of a document without sharing all of it.
3. PDF Compressor — Smaller Files, Same Quality
PDF Compressor reduces file size using in-browser image resampling and stream compression — no cloud processing required. Useful when email attachments stubbornly bounce because they’re too large.
The technical detail: Compression is performed by the browser’s Canvas API and the pdf-lib library. Every byte of your document stays on your machine.
4. PDF Watermark — Protect Before You Share
PDF Watermark overlays diagonal or positioned text (e.g. “CONFIDENTIAL” or your name) across every page before you send a document off. The watermark is baked directly into the PDF using client-side rendering — no upload step.
Use case: Consultants sharing draft reports with clients, photographers protecting proofs, HR teams distributing internal documents with attribution.
5. e-Signature — Sign Documents in the Browser
e-Signature lets you draw or type a signature and place it on a PDF without leaving your browser tab. The signed file is generated locally and downloaded directly to your device.
Note on legal validity: Digital signatures created client-side are suitable for many everyday business documents. For regulated industries requiring cryptographic signatures (e.g. eIDAS qualified signatures), consult a specialist service.
What to Do Next
Once you have your PDF sorted, here are the natural next steps:
- Compress it → PDF Compressor reduces the file for email attachments
- Protect it → PDF Watermark stamps attribution before sharing
- Sign it → e-Signature adds a signature in seconds
- Need a different format? → PDF to Word converts the file for editing
Frequently Asked Questions
Are these PDF tools really free with no catch? Yes. All five tools run entirely in your browser using your hardware. There are zero server costs for file processing on our side, which means zero fees for you — and no artificial file limits.
Do I need to create an account or give an email address? No account, no email, no signup of any kind. Open the tool, use it, close the tab. Nothing is stored on our side.
Is my PDF data private?
All processing happens locally in your browser using the pdf-lib library and browser APIs. Your PDF files are never uploaded to a server, stored in a database, or transmitted anywhere. The processing happens entirely within your browser tab.
Can I use these tools on a phone or tablet? Yes. The tools work on any modern browser including Chrome, Safari, and Firefox on iOS and Android, though a desktop or laptop offers the most comfortable experience for multi-file workflows.
What is the maximum file size supported? File size is limited only by your device’s available RAM. Most consumer devices handle PDFs up to several hundred megabytes without issue.
