Screenshot Pixelate
Light & color
Saves the edited image at its current dimensions. JPG, PNG, and WebP keep their format; other supported inputs download as JPG. Check the downloaded file for final quality.

Pixelation is the honest censor: unlike blur, it shows everyone that something was hidden, and unlike cropping it keeps the layout intact. Block out names, emails, prices or UI regions with a block size you control, processed locally in your browser.
That visible-on-purpose quality is exactly why pixelation is the convention in bug reports, tutorials, and support threads. A reader can see at a glance that a value was deliberately removed rather than wondering whether a smudge is a redaction or a rendering glitch. Because each block replaces its area with a single averaged color, a large enough block size destroys the underlying detail outright, so the result is both clearly redacted and genuinely unrecoverable.
How to use the screenshot pixelate
- Add the screenshot that needs content blocked out.
- Drag the pixel-size slider: larger blocks hide more.
- Press Apply and download the result.
Choosing a block size
Match the block size to what you are hiding. To black out an email address, an API key, or a price, use large blocks, 40 pixels and up, so several characters collapse into each block and nothing can be read back. This is the setting to use whenever the hidden value would actually matter if it leaked.
Smaller blocks are only for cosmetic cases, like softening a face in the background of a UI demo where the exact identity does not matter. Avoid tiny 4–8 pixel blocks on text you truly need secret: at that scale, simple, predictable characters can sometimes be reconstructed. When in doubt, err toward bigger blocks, since over-hiding costs you nothing and under-hiding can leak the very thing you meant to remove.
Frequently asked questions
Pixelate or blur: which hides better?
At strong settings both are unrecoverable. Pixelation also communicates: viewers see clearly that content was redacted, which builds trust in bug reports and tutorials. Use large blocks (40px and up) when secrecy matters.
Does pixelation leave any recoverable data?
At large block sizes, no: each block is an average, and the underlying detail is destroyed. At tiny block sizes (4–8px), determined reconstruction of simple text is occasionally possible. Size your blocks to the stakes.
Can I pixelate just one part of the screenshot?
Pixelation applies to the image you give it; the practical workflow for a single region is to crop to the sensitive area, pixelate it hard, or simply crop that area away if it does not need to be shown at all. For scattered sensitive details, whole-image blur is often the faster safe default.
