Free Offline PDF Tools

Merge, split, compress, rotate, watermark and convert PDF files in your browser. No upload, no account - your documents stay on your device.

No Upload 100% Private Works Offline Free

Process PDF files without uploading them

PDF files often contain sensitive content — contracts, financial statements, medical records, personal identification. These tools let you merge, split, compress, convert and watermark PDFs entirely in your browser using PDF.js and pdf-lib. Nothing is ever transmitted to a server.

Unlike cloud PDF services that charge monthly fees and store your uploads, these tools are free, require no account, and work entirely offline after the initial page load. They are GDPR-friendly by design — no personal data processing occurs on any server.

Processing speed depends on your device. PDF files up to several hundred pages typically process in seconds. There are no file size limits from our side.

Why offline PDF tools matter for privacy

Confidential docs

Contracts, NDAs and financial reports should never be uploaded to a third-party converter. These tools keep them on your device.

GDPR compliant

Because no data is sent to a server, there is no personal data processing — fully aligned with GDPR, HIPAA and similar regulations.

No size limits

Cloud PDF tools cap uploads at 10–25MB. Browser-based tools have no server-side limit — process any PDF locally.
