The converter downloads once (about 32 MB), then works offline. Your videos stay on your device.
Timing is the whole joke
The same clip lands completely differently at half speed versus 4x. Reaction GIFs get funnier sped up; process demos get clearer slowed down. QuietPix rescales the frame timing and regenerates the color palette on your device, so you can iterate on the timing until it hits, without ever waiting for an upload.
Frequently asked questions
How do I speed up or slow down a GIF?
Pick a speed (from quarter speed to 4x), drop the GIF, download. The timing of every frame is rescaled and a fresh color palette keeps the result sharp.
Does changing speed lose frames?
Speeding up compresses frame timing; at high multipliers some frames merge, which is what makes it look fast. Slowing down keeps every frame on screen longer.
Is my GIF uploaded?
No. The speed change runs in your browser via WebAssembly FFmpeg. Nothing touches a server.
What speeds are available?
0.25x and 0.5x for slow motion, 2x and 4x for fast forward. Need something else? Run the result through again to combine multipliers.
