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

You can combine dozens of files in a single batch, limited only by your browser's memory capacity.

No, the pages are stitched together exactly as they appear in their original source files.

Yes, you can simply drag and drop the file thumbnails into your desired sequence before clicking merge.

Most form fields are preserved, though if multiple documents share the same field names, their data may conflict.

Each page retains its original physical dimensions; the resulting document will simply contain mixed page sizes.
