Pixelate a screenshot
About to share a screenshot in Slack, a GitHub issue, or a blog post? Paste it here with ⌘V, drag over the parts that shouldn't be public — API keys, tokens, email addresses, customer names — and download a censored copy. The screenshot never leaves your machine.
Drag a rectangle over anything you want to hide. Each selection is censored instantly with the selected mode — mix pixelation, blur and bars freely in one image.
What to censor before sharing a screenshot
- Credentials — API keys, bearer tokens, session cookies, connection strings. These are the classic leak: one terminal screenshot in a bug report has ended many an on-call shift.
- URLs — query strings often carry session IDs, signed tokens, or internal hostnames. Check the address bar before sharing.
- People — emails, usernames, avatars, and customer data in tables. What's routine inside the company is a privacy leak outside it.
- The periphery — notification popups, other browser tabs, dock badges. The embarrassing leak is usually at the edge of the frame, not the center.
Pixelate vs blur for text
For hiding text, pixelation beats blur. Blur keeps averaged information about the characters in place, and under the right conditions lightly-blurred text can be partially reconstructed. Pixelation with a block size larger than the text height reduces each chunk of characters to a single flat color — there is nothing left to reconstruct. This page defaults to a chunky block size for exactly that reason; a solid black bar is the zero-ambiguity option when aesthetics don't matter.
Frequently asked questions
Is the screenshot uploaded anywhere?
No — and for screenshots this is the whole point. The image is opened, censored and saved entirely in your browser. A screenshot full of API keys never touches a server, including ours.
Can blurred text be recovered?
Sometimes, yes — research has shown that lightly blurred text can be partially reconstructed, because blur preserves averaged information about the characters. For text that must stay secret, use pixelation with a block size at least as large as the text height, or a solid black bar. Both are applied destructively here.
What's the fastest workflow?
Take the screenshot (⌘⇧4 on macOS, Win+Shift+S on Windows), come to this page, press ⌘V / Ctrl+V — the screenshot loads instantly without saving a file. Drag over the sensitive parts, hit Download.
Does it work with Retina / HiDPI screenshots?
Yes. The tool works at the image's native resolution, so a 2× Retina screenshot is censored at full sharpness and downloads at its original size.
Is it free?
Free, no signup, no watermark, no limits — it runs on your device, so it costs nothing to provide.
