Why convert PNG to MP4?
Turn PNG images — slides, graphics or screenshots — into a video file.
How it works
Set how long each image shows (3 seconds by default) and the background colour, then download an MP4. The conversion runs with ffmpeg compiled to WebAssembly, on your device.
Quality notes
MP4 has no transparency: transparent areas take the background colour you choose.
Common use cases
Turning slides into a video; posting graphics where only video is allowed.
