CnF WORKS

Free tools for the file formats
that get in the way.

no accounts. no uploads. no expiry. no rent.

Three Mac apps that do one annoying job properly and then get out of your way. Everything runs on your own machine — nothing you open, convert or create is ever sent anywhere, because there is nowhere to send it to. The whole app is free. Donate only if it helped.

$0 · always No sign-up Works offline Open source macOS 13+

Fuck subscriptions for tools that should be a file on your computer. No trial clock. No email gate. No feature held hostage. Download the whole thing for $0, keep it, and tip us only if it earns its place on your Mac.

Phuck QR

codes that don't expire.

A QR code factory that runs entirely in your browser. Every code is decoded back out of the finished image before you're allowed to save it — so the ones that quietly stop working get caught here, not on a thousand printed stickers.

  • Scan-verified export — the part the paid tools won't do
  • Links, Wi-Fi, vCard, email, SMS, calendar, and more
  • PNG, true vector SVG, print PDF with crop marks, sticker sheets
  • Batch a CSV into a ZIP. No row limit, no plan
  • Codes that never expire, because nobody is hosting them
Phuck QR generating and verifying a working QR code in the live app
Actual app, running live — the finished QR was decoded and scan-verified before export.
v1.4.0 MIT licensed One self-contained HTML file — email it, or put it on a USB stick

Phuck PDF

pdfs. phixed.

Edit, combine, split, organise, secure, OCR and convert PDFs on your own Mac. Redaction here genuinely removes the text from the file rather than drawing a black box over it — and every redacted save is re-opened and verified before you get it back.

  • Real redaction, verified after saving or the file is discarded
  • Merge, split, reorder, rotate, duplicate and delete pages
  • Encrypt, decrypt, watermark
  • OCR built in — no extra install
  • Export to Word, text, images; build PDFs from images
Phuck PDF open on a Mac with PDF combine, split, edit, security, OCR and convert tools
Actual Mac app, not a render — PDF combine, split, edit, security, OCR and conversion in one local tool.
v1.2.0 AGPL-3.0 Apple silicon & Intel Includes Tesseract OCR and Poppler — nothing else to install

Phuck HEIC

HEIC out. Photos in.

Batch convert iPhone HEIC photos into JPEG, PNG, WebP or TIFF — formats that everything can actually open. Converts several at once, keeps your capture dates, and never touches the originals.

  • Whole folders at a time, using every core you've got
  • Keeps EXIF and capture dates so photo apps still sort right
  • Or strip GPS and camera data on purpose, before sharing
  • Resize the long edge for email, web or storage
  • Originals are never modified. Cancel any time
v1.3.0 MIT licensed Apple silicon & Intel Also runs on Windows and Linux from source

Mac won't let you open it?

If macOS says the app “cannot be opened” or is “damaged”, that's Gatekeeper being cautious about a small publisher, not a problem with the file. On macOS Sequoia and later the old right-click → Open trick no longer works. Here's the current way:

  1. Double-click the app once and dismiss the warning.
  2. Open System Settings → Privacy & Security.
  3. Scroll down to the message naming the app, and click Open Anyway.
  4. Confirm with Touch ID or your password. You only do this once.

Want to check the download is intact first? Every release ships a .sha256 file beside it. Run shasum -a 256 ~/Downloads/PhuckPDF.dmg in Terminal and compare.

Nothing is uploaded

No servers, no telemetry, no analytics, no update pings. Unplug the network and everything still works.

No account, ever

No email, no sign-in, no free tier that runs out. You download it and it's yours.

Read the source

All three are open source. If you don't believe the claims above, go and check them.

They don't expire

No licence server to shut off. The copy you have today keeps working whatever happens to me.
