Redacted image

Download your image

Export your current regions to see the actual PNG here.

Only covered pixels are removed. Review the entire exported image before sharing. Information outside your regions remains visible.

PNG export preserves image dimensions and uncovered transparency, removes source metadata, and flattens the selected frame. Colors may change with browser decoding and sRGB conversion.

How to redact

  1. Choose an image from your device.
  2. Add regions, then move and resize them to fully cover private details. Leave enough space around text edges.
  3. Export the PNG, review the actual result, then download it. Export again after any edit.

Good to know

Can the covered pixels be recovered from the download?

The exported PNG replaces every pixel inside your rectangles with opaque black. It contains a flattened raster with no editable overlays or hidden source image. Details outside the selected rectangles remain, including anything that could help someone infer the covered information. Review the whole image before sharing.

Does my image leave my device?

No. Decoding and export run in your browser. The image is not uploaded or stored by this tool. The original stays in memory while you edit so you can change or remove regions. Clear image or leave the page to release it. Your original file on disk is unchanged.

Which formats and image features are supported?

JPEG, PNG, WebP and any other image your browser can decode. Output is always a still PNG at the oriented source dimensions. Animation becomes the single frame shown in the editor. Source metadata is removed; uncovered transparency is preserved. Browser decoding and sRGB export may change HDR or wide-gamut colors. PNG can be larger than the original.

Can I undo or cancel?

Before sharing, select a region to edit or remove it, or clear all regions and start again. A changed region hides the old download until you export again. Cancel & clear stops an active operation and releases the image. Available memory and browser capabilities determine which images can open; unsupported or damaged files show an error.
