Which effect should I use for sensitive information?

Use Redact. It places a fully opaque solid cover over the chosen pixels. Blur and pixelation are visual obfuscation effects and may leave recognizable information.

Can redaction areas be circular?

Regions can be rectangles or ellipses. Select an existing region to change its shape without redrawing it.

Can different areas use different effects?

Yes. Every region keeps its own effect and settings, so one image can combine blur, pixelation and opaque covers.

Does saving remove the hidden source pixels from the output?

The exported image is newly rendered with the chosen effects. For confidential content, an opaque Redact region replaces those visible pixels in the saved result.

Frequently asked questions

About Blur, Pixelate & Redact Image

Blur, Pixelate & Redact Image distinguishes privacy removal from cosmetic concealment. Blur softens detail, pixelation replaces it with enlarged color blocks, and Redact applies an opaque solid region for information that must not remain visible in the exported image.

Each rectangular or elliptical region remains independently adjustable until saving. This makes it practical to cover names, faces, account numbers or screen details with the treatment appropriate to each area. The editor preserves the source format and performs rendering locally.
