Is my GIF uploaded anywhere?
No. Decoding, censoring, and re-encoding all happen locally in your browser. That matters more than usual here, since GIFs you censor often contain exactly the information you don't want on someone else's server.
Blur & Censor GIF Online
Draw a box over the part you want hidden, pick blur, pixelate, or a solid bar, and it's applied to every frame of the animation. Everything runs locally in your browser — the safest way to censor sensitive GIFs.
Frequently asked questions
Can a blurred or pixelated area be reversed?
Strong pixelation and downscale-based blur discard image data, so they can't be simply undone. For maximum certainty on highly sensitive content, use the solid bar — it replaces the pixels completely.
Does the censor box move with the subject?
No — the box stays in the same spot on every frame. That works great for fixed overlays like usernames, timestamps, or license plates in mostly static shots. If the subject moves a lot, draw a slightly larger box to cover its whole path.
Which censor style should I pick?
Pixelate is the classic mosaic look and reads clearly as "redacted". Blur is softer and less distracting. A solid bar is the most thorough since it fully replaces the area — the usual choice for names and IDs.
Will the GIF quality change?
The GIF is re-encoded after editing, so file size can shift slightly, but dimensions, timing, and loop settings are preserved. Areas outside your censor box keep their original look.
What if I need to censor a video instead?
GIF censor is for animated GIFs and has no audio. To redact an mp4 or similar video and keep the soundtrack, use the video censor tool.
