Frequently asked questions
Does blur censor sensitive info?
Warning: blur can be partially reversed by specialized algorithms (deblur, super-resolution). For strong censoring, use solid black rectangles (not this tool).
Blur only part of image?
This version applies to entire image. For specific area, crop first, blur, then composite back (future version).
Why does file size grow with blur?
PNG is lossless and blur creates smooth gradients that compress poorly. To reduce, export as JPG.
Maximum blur radius?
50px in this version. Beyond that, performance degrades.
Output format?
PNG only.
