Why use this tool

Every PDF task, one place

Merge, split, compress, convert, sign, and more — no need to juggle separate apps for each job.

Private by default

Most tools process your file entirely in the browser — it's never uploaded. When a conversion needs the server, the file is deleted within the hour.

Works on any device

Runs in the browser on Windows, Mac, Linux, iOS, and Android — nothing to install, nothing to trust but the tab.

Fast by design

No queues and no desktop app to wait on — most jobs finish in a few seconds, right where you are.

Convert to and from any format

Move between PDF, Word, Excel, PowerPoint, images, and HTML — output stays true to your original formatting.

Free, always

Every tool here is free to use, with no watermarks, page limits, or forced trial period.

This is a structural repair tool, not an antivirus scanner. It will not clean malicious payloads from infected files.
