Why people use Racks

Unlimited and free

No page limit, no file size limit, no tasks-per-hour limit and no watermark on your PDF.

Edit without changing the font

Retyped text uses the font, size and color already in your PDF, so the edit blends in.

Private by design

Your file is opened and saved in your browser. It is never uploaded to a server.

No sign-up

Open a tool and start. There is no account, no email and no trial.

Questions and answers

How many PDF files can I merge?

As many as you like. There is no file count or hourly limit.

Will merging reduce the quality?

No. Pages are copied as they are, so text, images and links stay unchanged.

Are my files uploaded?

No. The merge runs inside your browser on your own device.
