Why this tool is useful
Prepare a GIF for a fixed message, documentation or interface slot without exposing the animation to an external conversion service.

Private Animated GIF Resizer
Resize every composited frame of an animated GIF to exact bounded dimensions while preserving frame order and timing entirely in the browser.
Ready. Your working data stays in this browser.
Files and capture streams stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy.
How it works
The browser fully composites each bounded source frame, scales it to the requested canvas and re-encodes the animation with its original per-frame delays.
Practical example
Choose a 900 × 600 animation, request 450 × 300, verify the new dimensions and download a two-times-smaller canvas with the same timeline.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
