ExportFlattened pixels
Permanently cover private screenshot pixels, add outlines or text, and export a flattened PNG or PDF without embedding the original underneath.
Step by step
01Choose the source
Choose a screenshot or try the sample account page. Images are decoded on this device and limited to a manageable working resolution. Check the output-pixel readout before editing a very large screenshot.
02Edit and inspect
Select opaque black redaction and drag boxes over private information. Add red outlines or text to explain useful context. Select layers in the inspector to remove them; undo and redo let you correct recent markup.
03Export and verify
Download a safe PNG or flattened PDF and inspect the saved file before sharing. Only black boxes are redactions: an outline or a text annotation does not hide the original pixels. Cover every visible identifier, including repeated names or details in the background.
Why this one
Flattening is the security boundary
A black rectangle in an editable SVG can leave the original screenshot embedded underneath it. This editor offers only flattened PNG and PDF output. The export composites the markup into fresh pixels instead of distributing the source image plus removable overlay objects.
Opaque rather than blurred
Blur and pixelation can leave recognizable patterns or partial text. The redaction tool uses solid black pixels and slightly expands the covered rectangle to avoid leaving a thin visible edge. Review the selected region at useful zoom before export.
Annotations remain distinct
Red outlines and typed notes help explain a screenshot without claiming to conceal it. These use a separate tool mode and are counted separately from black redactions. Selection outlines are editor controls and do not appear in the downloaded file.
FAQ
The screenshot redaction editor writes black boxes into newly encoded PNG pixels or a flattened PDF image. The exported file does not retain a removable original-image layer underneath the boxes.
The screenshot redaction editor decodes the image and writes a new pixel-based export, so original EXIF metadata is not copied.
Red outlines in the screenshot redaction editor are annotations, not redactions. Use opaque black redaction boxes over sensitive details.
The screenshot redaction editor intentionally exports flattened PNG and PDF files. An editable SVG could retain private source pixels under removable boxes.
