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.
Frequently asked questions
PDF/A is a standardized format designed specifically for the long-term archiving of electronic documents, ensuring they open correctly decades from now.
It embeds all fonts, strips out interactive media (like audio or Javascript), and forces color profiles to ensure the file is self-contained.
Generally no, though unsupported elements like transparency or 3D models will be flattened or removed to meet strict archival standards.
The tool typically targets PDF/A-2b, which provides a good balance of modern features (like JPG2000 compression) and strict archiving rules.
Most viewers will lock the file as read-only to preserve its archival integrity, though the standard doesn't strictly forbid editing.
