Hiding sensitive information properly
For privacy, strength matters: a light blur on large text can still be readable. Use a strength of at least 15–20 px for text, or pixelate with large blocks. Remember the area is fixed — if the thing you’re hiding moves across the GIF, draw the box large enough to cover its whole path, or trim to the part where it stays put.
Because processing happens on your device, the unblurred original is never sent anywhere — important when the GIF contains screen recordings of emails, dashboards or documents made with the GIF Recorder.
Creative blur
Blurring the whole GIF lightly creates a dreamy background for text overlays — blur, then add text. To remove distractions at the edges instead, crop. For colour effects, see GIF Filters.
