A lightweight macOS app that equalizes all pages of a PDF to the same width.
Lossless media box adjustment · Drag & drop · Universal Binary (arm64 + x86_64)

---

Pages are adjusted by modifying the page media box — no re-rendering or quality loss. Useful when scanned documents or merged PDFs have inconsistent page sizes.

Features

• Drag & drop a PDF onto the window or the Dock icon
• Equalizes all pages to match the widest page in the document
• Replace original file option to overwrite the source PDF directly
• Outputs a new file with _equalized suffix by default

Download

Download the latest universal binary (Apple Silicon + Intel) from the Releases page.

Opening the app (unsigned)

Since the app is not signed with an Apple Developer certificate, macOS will block it on first launch. To open it:

1. Right-click (or Control-click) on PDF Equalizer.app
2. Select Open from the context menu
3. Click Open in the dialog that appears

You only need to do this once. After that, the app will open normally.

Alternatively, you can remove the quarantine attribute via Terminal:

xattr -d com.apple.quarantine "PDF Equalizer.app"

Build from source

Requires Xcode Command Line Tools on macOS 12.0 or later.

# Debug build (current architecture)
./build.sh

# Universal binary (Apple Silicon + Intel)
./build-universal.sh

The built app will be in build/ or build-universal/universal/.
