What the video converter does
KoalaPic converts video between MP4 and WebM, turns a video into an animated GIF, turns a GIF back into a video, and pulls a single frame out as a still image. It runs ffmpeg on our servers, accepts clips up to 100 MB and five minutes, and deletes both the upload and the result an hour later.
Limits and defaults
- Maximum upload 100 MB and 300 seconds; audio-only files are rejected because there is nothing to convert.
- GIF output is capped at 640 pixels wide and 30 seconds, which is where the format stops being practical to load.
- GIFs are built with a two-pass palette, which produces noticeably better colour than a single-pass conversion.
- Codecs are chosen for the output format automatically — H.264 for MP4, VP9 for WebM — and quality is set by CRF.
- Frame extraction takes a timestamp and writes a still image at the resolution you ask for.
How do I turn a video into a GIF?
Upload the clip, choose Video to GIF, and set the frame rate, width and the section you want. KoalaPic builds a colour palette from the footage first and then encodes against it, which avoids the banding a straight conversion produces. GIF output is limited to 640 pixels wide and 30 seconds.
Why is my GIF so much larger than the video it came from?
GIF stores every frame as a palette-indexed bitmap with no motion compression, so a clip that is a few megabytes as MP4 can be tens of megabytes as GIF. Reducing the frame rate and the width is far more effective than reducing the length. Converting a GIF to MP4 or WebM typically cuts the size by more than 90%.
What is the maximum video length I can convert?
Five minutes, and 100 MB, whichever you reach first. The limit exists because conversion runs synchronously on shared workers; longer footage is better trimmed to the section you actually need before uploading.
Can I extract a thumbnail from a video?
Yes. Choose Extract Thumbnail, give a timestamp, and KoalaPic writes that frame as an image in the format and size you specify. It is the same operation a video platform runs to build a poster frame.
