Blur & Pixelate Image
Redact sensitive data, hide faces, and censor confidential text by dragging to blur or pixelate in your browser.
Irreversible Privacy and Redaction Protection
Sharing screenshots, scanned identification cards, utility bills, and receipts on public forums or social networks often requires concealing sensitive information. Blacking out or blurring details using poorly designed mobile markup tools can accidentally leave underlying image layers intact, allowing malicious actors to recover data by adjusting brightness and contrast.
OnlyFiles Blur & Pixelate tool renders redactions directly into the target pixel bitmap. When you download your censored file, the underlying pixels within the selected region are mathematically averaged and permanently destroyed. No software or forensic tool can revert the redacted area back to the original text or facial features.
True Pixel Destruction
Mathematical downsampling and box averaging irrevocably overwrite the selected region before generating the final image file.
Intuitive Drag-to-Select
Simply click and drag your cursor over faces, license plates, house numbers, or credit card digits to target the exact area to obscure.
Guaranteed Confidentiality
Your confidential documents never touch an external server or API. All rendering executes locally inside your web browser sandbox.

Frequently Asked Questions
Can blurred or pixelated information be unblurred by someone else?
No. When you download your image, the pixel manipulation is irreversibly baked into the new canvas pixel data. The original pixels under the blurred rectangle are permanently destroyed.
Are my sensitive photos uploaded to the cloud?
Never. All processing happens entirely inside your browser memory using HTML5 Canvas. Your confidential pictures and documents are never transmitted over the internet.
Can I blur multiple regions on the same picture?
You can redact an area, download the image, and re-import it to blur additional sections, or select the entire photo to apply a universal blur.
