Pixelate selected areas of an image

Manually pixelate, move and resize areas in an image. Free in your browser with no upload or account required.

Select the exact regions you want to obscure. Adjust pixel strength and multiple independent areas separately, then export an image or PDF.

How it works

Open a PNG, JPG, WEBP or another supported image.
Mark areas and adjust the pixelation strength.
Prepare and download a PNG, JPG or PDF.

Pixelation can obscure details but does not guarantee irreversible removal of sensitive information. Fully opaque black coverage is the more appropriate function for that purpose.

What happens to your files

Selected files and edits are not uploaded to a Schutzo server. A temporary local draft in your browser supports recovery in the same tab. It expires after ten minutes of inactivity. If the browser is closed, an expired draft is removed the next time the app opens. Language and theme preferences are stored separately.

Capabilities and limitations

PDF.js loads from an external CDN. Requests for application code may therefore leave your device; your selected documents are not uploaded with them. Maximum 200 MB per file and 200 pages per workspace. Images: up to 40 megapixels and 16,384 pixels per side; up to 80 megapixels in total.

PDF exports contain newly rasterized pages. The original text layer, searchability and PDF structure are not preserved. Blur and pixelation do not guarantee irreversible anonymization. Use fully opaque black coverage for sensitive content and check the exported file.

Frequently asked questions

Do I need an account?

No. You can use Schutzo without signing up.

Are my documents uploaded?

Document processing and export run in your browser. Your documents are not sent to our server for editing.

What happens after a refresh?

The last saved local draft can be recovered in the same restored tab if ten minutes of inactivity have not elapsed. A sudden crash may lose the most recent changes.

Are faces detected automatically?

No. You select the areas manually using a rectangle or ellipse.
