Frequently asked questions
Pixelation more reliably obscures fine detail like text or faces at typical strengths; a light blur can sometimes be partially reversed with sharpening tools, so pixelation is the safer choice for genuinely sensitive content.
Run the tool again on the output to apply blur to a second region — each pass targets one area at a time.
No — once applied and downloaded, the blur or pixelation is baked into the image pixels permanently, with no way to recover the original detail from the output file.
Because processing happens in your browser, obscuring a sensitive photo detail never means uploading the un-obscured original to do it.
