Blur vs. pixelate — which should I use?
Blur softens the whole image with a Gaussian-style smear. It looks clean and
is great for hiding a background or making text unreadable at a glance. Pixelate
replaces the image with large blocky squares — the classic "mosaic" censor look that reads
clearly as redaction.
For genuinely hiding text, faces or numbers, turn the strength up high. A light blur can
sometimes be partially reversed, so err on the strong side when the information is truly
sensitive. Both effects are applied to the entire image, so this tool is ideal
for obscuring a full screenshot or a whole photo.
🔒
Private by design. Everything happens right here in your browser using the Canvas API. Your image is never uploaded — we never see it.
Frequently Asked Questions
What's the difference between blur and pixelate?▼
Blur softly smears the image so details melt away. Pixelate replaces it with large blocky squares — the classic mosaic censor look. Both clearly read as redaction.
Does it hide the whole image or just one spot?▼
The effect is applied to the entire image, so it's ideal for obscuring a full screenshot or a whole photo rather than a single small area.
How strong should I make it to truly hide something?▼
Turn the strength up high. A light blur can sometimes be partly reversed, so when the information is genuinely sensitive — faces, addresses or numbers — err on the strong side.
What formats can I use and download?▼
Add a JPG, PNG, WEBP or GIF, and save the result as PNG, JPG or WEBP.
Will I lose the transparent background?▼
PNG and WEBP keep transparency. JPG has none, so any transparent areas are filled with white when you save as JPG.
Is my image uploaded anywhere?▼
No. Everything happens right here in your browser on your own device — your image is never uploaded and we never see it.
