Frequently asked questions

Does resizing remove animation?

No. Every frame is resized proportionally and re-encoded. Width 0 keeps the original width; enlarging cannot restore missing detail.

Are my files uploaded?

No. Decoding and processing happen on your device.

What should I check before using the output?

Up to 30 seconds of video or 300 GIF frames. Large inputs may exceed browser memory. Video outputs are silent and MP4 does not preserve transparency; colors and timing can change during re-encoding.
