Plain Text Cleaner PasteZen
Paste Clean, Remove Formatting
Only for Mac
Free · In‑App Purchases
Mac
Paste plain text without thinking about it. PasteZen cleans formatting, tracking links and PDF line breaks the moment you copy, 100% offline. No subscription.
Paste as plain text, every time. PasteZen removes formatting, tracking links and hidden characters the moment you copy, so whatever you paste comes out clean.
It works offline. PasteZen has no network access at all, so nothing you copy ever leaves your computer.
WHAT IT CLEANS, AUTOMATICALLY
• Fonts, colors, sizes and rich-text styling, down to clean plain text
• Tracking parameters in copied links (utm_source, fbclid and more)
• Broken line breaks in text copied from PDFs
• Invisible and zero-width characters, including the ones some AI tools add
• Leftover Markdown symbols (** and ##) in answers copied from AI chats
• API keys, card numbers and email addresses, masked before you paste, with a way to see the original
WORKS THE WAY YOU ALREADY COPY
Copy as usual. PasteZen cleans in the background from the menu bar. Want something different this time? The Quick panel (⌥⌘V) lets you pick a transformation or change the case, a Services menu item works in any app, and Skip Next lets one copy through untouched.
YOU DECIDE, APP BY APP
Choose how much PasteZen does in each app: full cleanup in your email, light cleanup in your code editor, nothing at all where you want your text exactly as copied. Copies marked as passwords are always left alone.
100% OFFLINE, AND YOU CAN CHECK IT
PasteZen is built without the network entitlement, so the system itself stops it from going online. Click 100% Offline in the menu bar window to see its offline certificate, with a fingerprint you can verify in Terminal.
PLAYS WELL WITH CLIPBOARD MANAGERS
Co-Exist mode gives clipboard history apps a chance to keep your original copy. It is best effort, not a guarantee for every app.
FOR POWER USERS
Turn every cleanup step on or off, try changes live in the Playground, and write your own JavaScript transform in a sandboxed editor.
FREE CORE, ONE-TIME PRO
Plain-text cleanup, app rules and undo are free. Try every Pro feature free for 3 days, then unlock Pro with a single one-time purchase. No subscription.
PasteZen is not a clipboard history manager. It does one thing, cleans what you copy, and stays out of your way.
