Is my screenshot uploaded anywhere?

No. The editor is built on the browser canvas API and every operation happens on your device. You can load the page, go offline, and keep redacting.

Which redaction style should I use for passwords or ID numbers?

Always the solid box. It physically overwrites the pixels, so the information is gone from the exported file. Blur and pixelation transform pixels rather than destroy them, and weak settings on short text can sometimes be reversed.

Can blurred or pixelated content really be recovered?

Sometimes, yes. For structured content like short text, license plates or faces, researchers have demonstrated reconstruction from weak blur or coarse mosaic — especially when the font is known or several frames exist. High-strength settings make this much harder, but a solid box makes it impossible.

Does the exported image keep EXIF metadata?

No. The result is rendered from canvas, which produces a brand-new file containing only pixels. Location, timestamps and device info from the original are not carried over.

Does it work on a phone?

Yes. The editor uses pointer events, so you can draw selections with your finger. The rectangle tool is usually easier on small screens; the brush works well for irregular shapes.

Redact Sensitive Info

Screenshot Redactor — Blur, Pixelate & Black Out

Hide names, faces, addresses and account numbers in screenshots before you share them. Runs entirely in your browser.

Drop images here or click to select

JPG, PNG and WebP — you can also paste a screenshot with Ctrl+V / Cmd+V

Processed locally, never uploaded

100% private — your images never leave your device

Everything on this page runs locally in your browser with JavaScript. No image is ever uploaded to a server, so you can safely process ID photos, screenshots with personal data, or any confidential picture.

How the redactor works

Load your screenshot

Drop an image, pick it from disk, or just paste it with Ctrl+V / Cmd+V straight from your clipboard. Nothing is uploaded — the editor is pure client-side canvas.

Mark what should disappear

Drag rectangles over names, emails or faces, or use the brush for irregular shapes. Choose blur, pixelation, or an unrecoverable solid box. Every step can be undone.

Export a clean copy

Download as PNG or JPG. The exported file is rendered from canvas, which means all EXIF metadata is dropped automatically as a bonus.

Blur vs. pixelate vs. solid box — which is actually safe?

Not all redaction is equal. A solid box physically replaces the pixels with a flat color: the original information is gone from the file and cannot be recovered by anyone. This is what you should use for passwords, ID numbers, bank details and anything genuinely sensitive.

Blur and pixelation look cleaner, but they transform pixels rather than destroy them. Research has repeatedly shown that heavily structured content — short text, license plates, faces — can sometimes be reconstructed from weak blur or coarse pixelation, especially when the attacker knows the font or has multiple frames. If you use them, use high strength, and never rely on them for text secrets.

One more overlooked risk: cropping or covering things in an office suite or a notes app sometimes only hides the content visually while the original stays embedded in the file (a famous failure mode of PDF and DOCX redaction). This tool renders a flat bitmap from canvas, so what you see in the export is literally all the data there is — plus the metadata is stripped in the process.
