Why a solid mask is easier to verify
A screenshot can contain names, email addresses, order numbers, message previews, or a browser tab you did not intend to share. Blur and pixelation can leave recognizable patterns. A fully opaque rectangle is easier to inspect: the exported copy replaces the covered pixels with a solid color. It does not help if you miss the detail or another copy appears elsewhere in the image.
Choose the image and mark each region
Open the Image Redactor and select one static JPG, PNG, or WebP image. Drag over a region with a mouse, pen, or finger. On a narrow screen, zoom the page before placing a mask or use the exact pixel-coordinate fields. Use a separate mask for each detail and cover a little extra around text so antialiasing or a nearby character is not left visible.
Create and inspect a flattened copy
Select Create flattened copy and wait for the result preview. The browser redraws the source pixels, paints each mask directly onto a new canvas, and exports a new PNG or JPEG file. The source image is not overwritten. Inspect every masked region at full size, then scan the rest of the image for repeated details, browser chrome, reflections, notifications, and context that might identify someone.
Keep the limits in mind
The tool does not run OCR, identify private data, certify metadata removal, or provide legal or forensic redaction. It cannot verify that your masks are complete. JPEG output is re-encoded and may change image quality; PNG output may be larger. Keep the original private and share only after you personally review the exported copy.
Example workflow
Before posting a support screenshot, cover the account email and ticket number with separate solid masks, export a PNG, reopen the downloaded copy, and inspect it at full size. If the image contains private details beyond what is necessary to explain the issue, crop or replace the screenshot rather than masking it.
