Everyday PDF page edits. Nothing leaves your computer.

A small Windows app for splitting, trimming, reordering and merging PDF pages. The demo below is its named-range split. Move the cuts and the filenames update with the same rules the app uses.

Windows · unsigned, so SmartScreen asks once. Or run from source in two lines.

1 The folder you chose last time, ready at launch. If it's gone, files go beside the original. 2 Shown only while it works. Stops before the next file; saved files stay.

report.pdf · 95 pages · opened read-only

Drag a cut line, or focus one and press ← →. Rename any range.

  • pp. 1–1010 pages saves asIntroduction.pdf
  • pp. 11–8070 pages saves asMain content.pdf
  • pp. 81–9515 pages saves asAppendix.pdf

Filenames here follow the app's own rules: characters Windows forbids become -, and a name already taken picks up a number. Try typing Re/port, or giving two ranges the same name.

Seven operations

The fine print

What SlicePDF does on every run, and what it does not support.

Every run

Never overwrites
A name that's already taken gets a number: Appendix-2.pdf.
Leaves the original alone
Your source PDF is only read, never changed.
Keeps links and bookmarks
Ones pointing at a page the new file doesn't have are dropped.
Remembers your output folder
The folder you chose last time is ready at launch. If it has moved or been deleted, files go beside the original.
Stops when you cancel
Before the next file. Files already saved stay where they are.
Stays on your computer
No uploads, no account, no tracking.

Not supported

Page previews
You work from page numbers.
Batch processing
One PDF at a time, or one set of PDFs to merge.
Password-protected PDFs
Refused when you open them. A PDF that opens without a password works.
Document properties
Title and author are not copied into the new files.
macOS or Linux
It relies on Windows font loading and Windows filename rules.
Code signing
The build is unsigned, so SmartScreen asks once.

If one of these blocks you, open an issue and say so.

Install

One executable, or two lines of Python. Both give you the same app.

The executable

  1. Download SlicePDF.exe. It is one file with nothing to install.
  2. Windows shows a SmartScreen warning because the file is not code-signed. Choose More info, then Run anyway.
  3. Drag a PDF onto the window, or use Choose PDF.

To check the download, run Get-FileHash .\SlicePDF.exe -Algorithm SHA256 and compare it with SlicePDF.exe.sha256 on the latest release.

From source

Needs Python 3.14 on Windows.
