Features / Offline PDF Editor

A PDF editor that runs 100% offline

Merge, split, compress, sign, redact and annotate PDFs entirely on your own Mac or PC. No file ever touches a server — so confidential contracts, tax forms and medical records stay private. Pay once, not every month.

100% offline · No upload · Free for 8 files/day

The problem with cloud tools

Online and cloud-based alternatives come with real trade-offs.

Your documents get uploaded

Tools like Smallpdf, iLovePDF and Adobe cloud require you to upload every PDF to their servers. Sensitive contracts, IDs and financial records pass through third-party infrastructure you do not control.

Endless monthly subscriptions

Cloud PDF editors charge $7–$20 every month — forever. A few edits a year can quietly cost you hundreds of dollars while you keep paying for features you rarely touch.

No internet, no editing

Browser-based editors stop working on a plane, on hotel Wi-Fi, or behind a corporate firewall. File-size caps and daily limits get in the way exactly when you are in a hurry.

Everything an online PDF editor does — without the upload

  • Merge, split, reorder, rotate and delete pages in seconds
  • Compress large PDFs to shrink file size while keeping quality
  • Password-protect, encrypt, decrypt and set permissions locally
  • Redact sensitive content and strip metadata before sharing
  • Add text, highlights, annotations, watermarks and page numbers
  • Fill and flatten forms, run OCR, and convert to and from images

What you can do

Built for offline pdf editor that stays on your machine.

Merge & split

Combine dozens of PDFs into one, or split a long document by page or range — drag, drop, done.

Compress PDFs

Reduce file size for email and uploads without the blurry results cloud compressors leave behind.

Secure & redact

Encrypt with a password, set permissions, and permanently black out confidential text before sharing.

Annotate & sign

Add text, highlights, sticky notes and signatures, then flatten the result so edits stick.

Convert both ways

Turn PDFs into JPG or PNG and build PDFs from images — all processed on your machine.

Never uploaded

Every operation runs locally. Disconnect from the internet and the editor still works perfectly.

Frequently asked questions

Is 1FileTool a fully offline PDF editor?

Yes. Once installed, every PDF operation — merging, splitting, compressing, signing, redacting — runs entirely on your Mac or PC. No file is ever uploaded, and the editor works with your internet disconnected.

How does it compare to Smallpdf, iLovePDF and Adobe Acrobat?

Those tools process your PDFs on their cloud servers and charge a recurring monthly fee. 1FileTool keeps your documents on your device and is a one-time purchase from $29, with all PDF tools included on the free plan for up to 8 files per day.

Can I edit confidential or sensitive PDFs safely?

That is exactly what offline editing is for. Because nothing leaves your computer, contracts, tax forms, medical records and legal documents never pass through a third party — which also makes it a great fit for GDPR and privacy-sensitive work.

Does it run on both Mac and Windows?

Yes. 1FileTool is a native app for macOS (Apple Silicon and Intel) and Windows, with the same 39 PDF tools and identical functionality on both.

Is it free?

All PDF tools are free to use for up to 8 files per day. For unlimited processing, upgrade to Pro once from $29 — no subscription, with a 7-day money-back guarantee.
