Hungry monsters for your messy PDFs.
Straighten crooked scans, shrink bloated files, merge, split, OCR and redact. A whole pack of PDF tools that live together in one friendly desktop app.
One monster per chore.
Each tool is a monster that's really, really good at exactly one thing. Pick one, drop in a PDF, done.
Munch
Straightens skewed scans
Feed it crooked, phone-snapped or wonky-fed pages. Munch chews off the tilt and spits them back perfectly straight.
Squish
Shrinks file sizes
That 48 MB attachment the email server refused? Squish squeezes it down to something you can actually send.
Stitch
Merges PDFs
Drop in a pile of files, drag them into order, and Stitch sews them into a single tidy document.
Snip
Splits & extracts pages
Need pages 4–9 and nothing else? Snip cuts out exactly what you want and leaves the rest behind.
Peek
Makes scans searchable
Peek reads every word on your scanned pages so you can search, select and copy text like it was typed.
Hush
Redacts & strips metadata
Black out the sensitive bits for real — and wipe hidden author, location and edit history before you share.
They all live in the same house.
One download, every tool
No hunting for six different utilities. Install once and the whole pack moves in together.
Monsters work in teams
Chain them up: Munch straightens a scan, Peek makes it searchable, Squish shrinks it for email. One drop, three jobs.
Your files stay home
Everything runs on your own computer. Nothing gets uploaded to a mystery server to be "processed".
Works offline
On a plane, in a basement, behind a strict firewall — the monsters don't need Wi-Fi to eat.
Questions, answered.
Is PDF Monsters free?
Yes — download it and use every monster. No account required.
Do my files get uploaded anywhere?
No. All processing happens locally on your computer, so your documents never leave your machine.
Which platforms are supported?
macOS, Windows and Linux. Grab the build for your system from the download button.
Can I use just one monster?
Sure. Every monster is available from the app's home screen — open the one you need and ignore the rest. They won't be offended. Much.
Will there be more monsters?
The pack keeps growing. New monsters arrive through regular app updates, no extra downloads needed.
Adopt the whole pack.
One download. Every PDF chore, handled by a monster that loves doing it.
