Why blurring sensitive text isn't enough
Blurred and pixelated text looks hidden, but it often isn't. What visual obscuring actually does to your pixels, why it can be reversed, and what secure redaction means.

Hide a license plate in a photo
Selling a car, posting a dashcam clip frame, or sharing a street photo all put a license plate on the public internet, and a plate ties straight back to a person and an address through anyone with lookup access.
Draw a box over the plate and pick a mode. Plates are high-contrast text, which is exactly the kind of content that pixelation handles worst, so the tool nudges you toward solid fill and then verifies the covered pixels after export.

How it works
Drop or select an image — it opens locally in the editor.
Draw rectangles over sensitive content in Secure Black, Secure White, or Custom Solid mode.
Optionally switch to Blur or Pixelate for non-confidential cosmetic obscuring (a persistent warning explains the difference).
Review the region list, then export. The final image is rasterized into brand-new pixels.
The tool re-decodes the output and verifies every secure region contains only replacement pixels before offering the download.
What the tool does
- Secure Black, Secure White, and Custom Solid redaction modes
- Blur and Pixelate visual-obscuring modes, clearly labelled as non-secure
- Editable region list with per-region mode, delete, and one-click convert-to-secure
- One-click conversion of all blur/pixelate regions to secure solid redaction
- Pixel-level verification that secure regions contain only the replacement color
- Metadata (EXIF/GPS) is not carried into the exported image
How the result is verified
After export the tool decodes the output bytes again and samples every secure region to confirm the pixels exactly match the replacement color, and confirms the output carries no EXIF metadata. If any check fails, the download is blocked and marked Failed verification.
Frequently asked questions
Why is pixelating a plate risky?
Plates use standardized fonts on flat backgrounds, which makes them close to a best-case scenario for de-pixelation techniques. A solid rectangle leaves nothing to reconstruct.
Does this remove the location data too?
Yes, the re-encoded export carries no EXIF metadata, so GPS coordinates from your phone don't travel with the image. There's also a dedicated GPS removal page if that's all you need.
Understand the format

What your photos reveal: EXIF, GPS, and hidden thumbnails
A photo is more than its pixels. GPS coordinates, camera serial numbers, timestamps, editing history, and embedded thumbnails travel inside image files — here's what's there and how to remove it.
