Pixelate part of a YouTube thumbnail
Hide spoilers, faces, or brands in a thumbnail before it goes live — or pixelate something on purpose to build a curiosity gap. Drop in your 1280×720 thumbnail, drag over the area, download the PNG. Nothing is uploaded — handy when the video isn't public yet.
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 creators pixelate in thumbnails
- Spoilers — the result, the item, the reveal. A pixelated center-piece is the classic "watch to find out" device.
- Faces — bystanders who didn't consent, children, or a guest you're keeping secret until the video drops.
- Brands and logos — products you'd rather not appear to endorse, or marks that could trigger a claim.
- Screenshots inside the thumbnail — reaction-style thumbnails often embed a post or chat that needs names and handles hidden.
Thumbnail specs to keep in mind
YouTube thumbnails are 1280×720 (16:9), maximum 2MB, and most viewers see them at a fraction of that size — around 320px wide in the feed. That has two practical consequences: censor with chunky blocks so the effect reads at small sizes, and keep critical text away from the bottom-right corner where the duration badge sits. Download from this page as PNG and upload that file directly — flat pixel blocks survive YouTube's re-compression cleanly.
Frequently asked questions
What block size works best for a 1280×720 thumbnail?
Thumbnails render tiny in the feed, so subtle censoring disappears. Use a block size of 16 or more so the pixelation reads clearly even at 320px wide — this page defaults to 20. If the pixelated area is the hook of the thumbnail, go even chunkier.
Does pixelation in a thumbnail hurt click-through rate?
Used deliberately, it usually does the opposite — a pixelated face or item is a curiosity gap, and 'censored' content signals something worth uncovering. It's a staple of reaction and gaming thumbnails for a reason. Just make sure the rest of the thumbnail stays high-contrast and readable.
Will YouTube's compression ruin the pixelated area?
No — large flat blocks survive compression far better than fine detail. Download as PNG here, upload that PNG directly, and keep it under YouTube's 2MB thumbnail limit.
Is my thumbnail uploaded to your server?
No. Everything runs in your browser; the image never leaves your device. Useful when the thumbnail contains unreleased content.
Is it free?
Free, no signup, no watermark. It runs entirely on your device.
