AcornDoc

Organize PDF pages. Privately.

Drag pages into the right order, turn sideways pages upright and delete the ones you don’t need, then download the tidied-up PDF. Your file never leaves your device.

How it works

  1. 1

    Open your PDF

    Click Choose a PDF or drop the file here. Every page appears in the pages panel.

  2. 2

    Rearrange

    Drag pages into a new order. Use the buttons on a page to rotate it or delete it. Add pages from other files with + Add files.

  3. 3

    Download

    Click Download to save the new copy. Your original file stays unchanged.

Tidy up scans and long documents

Scanned pages often come out sideways, upside down or in the wrong order. Fix them in a few clicks: drag each page where it belongs, rotate the ones that need it, and remove blank or unwanted pages.

Pages keep their original quality: rotating and reordering doesn’t re-draw them. And like everything on AcornDoc, it all happens in your browser, so your document is never uploaded.

Can I undo a mistake?

Yes. Click undo at the top, or press Ctrl+Z, to bring back a deleted page or undo a rotation.

Can I save some pages as a separate PDF?

Yes. Use Split PDF to extract the pages you need into a new file.

Does it work on my phone?

Yes. Tap the pages icon in the toolbar to open the pages panel, then drag pages or use the buttons on each one.

What you can do

Tips & limits

A few things worth knowing before you start.

Hiding private details? Use Redact, not white-out. White-out only covers text: it's still inside the file and can be copied or found by search. Redact removes it for good by saving that page as an image.

Questions

Are my files uploaded anywhere?

No. Your PDF is opened, edited and saved entirely inside your browser. It never reaches our servers, and we can't see it.

Is it really free?

Yes. There's no account, no trial, no page limit and no watermark on your files.

Will my original file be changed?

No. Download saves a new copy (named “…-edited.pdf”). The original file on your device is never touched.

How do I edit text that's already in the PDF?

Use White-out to cover the old words, then use Text to type the new ones on top. Remember that the covered text is hidden, not deleted.

How do I change or remove something I added?

Choose Select (or press V), click the item, then drag to move it (even onto another page), drag the round corner handle to resize, or press Delete. Undo works too.

Does it work on my phone?

Yes, in up-to-date Chrome, Safari, Edge and Firefox. Tap the panel icon in the toolbar to see your pages. Detailed edits are easier on a larger screen.

Why does some of my text show as “?”

Added text currently supports Latin letters only (English, Spanish, French, German and similar). Support for more alphabets is planned.

How big can my file be?

Up to 200 MB. Everything happens on your device, so very large files may be slow on older phones.

Will links and form fields in my PDF still work?

Yes, in most cases. If you rotate a page and add something to it, links and form fields on that page are removed. Redacted pages are saved as images, so their links and text selection go too.

How accurate are measurements?

As accurate as the drawing’s scale. Scanned or resized drawings may not match their printed scale, so calibrate against a dimension you know and double-check critical lengths.
