Frequently asked questions
Which mode should I use for private text?
Use solid black cover. It replaces every pixel inside the selected rectangle with opaque black, without retaining the original pixels underneath. Blur and pixelation preserve patterns and are unsuitable when a name, account number or other sensitive detail must not be inferred.
Can blur or pixelation be reversed?
Even when the original pixels are absent from the exported file, a blurred or pixelated pattern can reveal information through context, comparison or reconstruction. Increasing strength is not a guarantee. Use opaque covers for confidential information, and include a margin so fragments of characters do not remain around the edges.
Does the downloaded image contain editable cover layers?
No. PNG and JPG exports contain the flattened result, with no separate rectangle layer to hide or remove. The original file on your device is not modified. Flattening does not protect details you missed, such as a reflection, another occurrence of a name or information visible elsewhere in the image.
What happens to EXIF metadata and the filename?
The export is generated from a new canvas, so the source file’s EXIF fields, embedded thumbnail and GPS tags are not copied. This does not remove information visibly printed in the picture. The download name is based on the original filename with a censored suffix; rename it if the original name contains private information.
Do all boxes use the same effect?
Yes. Changing mode applies the selected effect to every rectangle, and the strength slider affects every blur or pixelated region. Solid cover has no strength setting because it is fully opaque. Undo removes the most recent rectangle; Reset removes them all.
Should I save as PNG or JPG?
PNG keeps the exported pixels losslessly and is a useful choice for screenshots and text. JPG is usually smaller for photos but re-encodes the entire image with lossy compression. Both preserve the original image dimensions; both need to be inspected after download. No image is uploaded to process or export it.
About this tool
Start by deciding what the recipient actually needs to see. A screenshot may contain a name in the header, another in a message, an email address in a sidebar and a document title in the filename. Covering one occurrence does not hide the others. This tool provides manual rectangles rather than automatic detection, so finding every detail remains part of the job.
For confidential information, the default mode uses solid black fill. A rectangle drawn on the preview is mapped to the image’s original resolution and its covered pixels are replaced there. The thin selection outlines are editor guides and are not included in the download. Adding a margin around a detail helps prevent partial letters, shadows or nearby labels from revealing it.
Blur and pixelation are included for visual effects, such as softening a distracting background or giving a photo a mosaic treatment. They should not be treated as reliable redaction of secrets. If you switch away from solid cover, the tool changes every rectangle and displays a reminder beside the controls.
The original stays on your device and the download is a new, flattened image. Open that saved file before sending it: zoom in on rectangle edges, check areas you did not cover, and inspect its filename. When the image is extremely sensitive or the surrounding context identifies the subject, sharing a smaller crop or withholding the image may be more appropriate than adding more boxes.
