Editor · macOS 11+ · Windows 10+

Everything the editor does, one line each.

No roadmap items, no “coming soon”, nothing that is half wired up. Each line below is a tool you can use today on macOS and Windows, and every one of them runs on your own machine — the editor makes no network call to open, change or save a document.

Put the document together

  • Merge PDFs

    Combine several PDFs into one file, in the order you drop them in.

  • Split a PDF

    Cut a document into separate files, either one file per page or by a page range you type.

  • Extract pages

    Select the pages you want and save just those as a new document.

  • Reorder pages

    Drag pages into the order you want and apply the new order to the file.

  • Rotate pages

    Turn one page or a whole selection left or right.

  • Delete pages

    Remove pages you do not need, one at a time or as a selection.

  • Insert another PDF

    Drop the pages of a second document in at the point you choose.

Change what the file is

  • Compress a PDF

    Make the file smaller before you send it, without uploading it anywhere first.

  • Run OCR on a scan

    Turn a scanned page into text you can select and search, on your own machine.

  • Convert to PDF/A

    Produce the archival format that record-keeping rules ask for.

  • Validate PDF/A

    Check a document against the archival standard and see what it says, in the same window.

  • Export

    Open the export dialog from the toolbar, the command palette, or Ctrl+E.

Sign and check signatures

  • Sign with your own certificate

    Pick a .p12 or .pfx file you already have and sign the document with it, on this machine.

  • Check the signatures in a file

    See which signatures a document carries and whether they still hold.

Control what leaves the building

  • Redact

    Black out a passage so the words underneath are gone from the file, not covered up.

  • Password-protect a PDF

    Set or remove a password and the permissions that travel with it.

  • Watermark

    Put a text watermark across every page.

  • Edit the document metadata

    Change the title, author and the rest of what a reader's PDF viewer shows in Properties.

Mark up and annotate

  • Draw on a page

    Freehand ink, straight onto the document.

  • Underline and strike through

    Mark a passage the way you would on paper.

  • Attach a file

    Carry a second file inside the PDF, and take it out again.

  • Read an invoice

    Pull the fields out of an e-invoice and check them against the rules for one.

Read a long document

  • Page through the document

    First page, last page, next, previous — by button, by arrow key, or by typing a page number.

  • Jump by the outline

    Use the document's own bookmarks to move between chapters.

  • Search the text

    Find a phrase in the document you have open.

  • Zoom and fit

    In, out, back to actual size, or fit to the width of the window.

  • Full screen

    Drop the interface and read the page on its own.

  • Read aloud

    Have the page read to you by the voice your operating system already has.

Get through the work

  • Command palette

    Ctrl+K, then type the name of the thing you want; the shortcut sheet lists the rest.

  • Switch modes

    Read, review, organise, convert, sign, forms and protect are separate rooms, and the number keys move between them.

  • Undo and redo

    Step back out of anything you just did to the document.

  • Save and save as

    Write the document back where it came from, or somewhere else.

  • Print

    Send the open document to a printer.

The editor with a document open and the toolbar across the top

Where this list comes from

The editor keeps a register of its own interface. A walker starts at every control the app puts on screen, follows it through to the command it reaches, and records whether a test names it and whether a job runs that test. Only a control that passes all four checks is marked wired, and only a wired control is allowed on this page.

That rule is enforced by this website’s build, not by a habit: if a tool above stops being wired in the editor, the next deploy of this site fails until the line comes off. It is a deliberately one-way arrangement — the page can lag behind the app, and it cannot run ahead of it.

Read from the editor trunk at commit 4d22d4968 on 2026-09-09. Buttons and panels that exist but are not yet proven by a test are left out on purpose, so this page is shorter than the app. Text editing is one of them today.

What the editor does not do

Worth saying plainly, because comparison sites ask for these by name and we would rather you find out here than after installing.

  • Document storage. Your files stay where you put them; there is nothing to store them in.
  • Capture from a scanner or a camera. Bring a file that already exists.
  • A searchable library across your documents. It opens one document at a time.
  • Collaboration, review routing, or shared comments between people.
  • Making a PDF out of a Word file. It converts out of PDF, not into it.

All 33 of them, free.

Free for everyone, including at work. No account, no upload, no time limit.
