Frequently Asked Questions

Can I convert large MP4 files?
Yes, you can convert files up to 100MB directly in your browser. For larger files, consider splitting them before conversion.
Is my video uploaded to the server?
No. All conversion happens locally in your browser using FFmpeg compiled to WebAssembly. Your privacy is fully protected.
Which formats are supported?
You can convert MP4 to GIF, WebM, or a sequence of PNG images. Each format has options for FPS and resolution.
Can I adjust frame rate or resolution?
Yes. You can select FPS (frames per second) and output width for your converted video or image sequence to optimize quality and file size.
How do I preview the conversion?
The tool provides a preview of the converted GIF or WebM video after conversion, so you can check before downloading.
Can I convert multiple videos at once?
Currently, only single video conversion at a time is supported. However, PNG sequences can be downloaded as a ZIP for batch frames.
Which browsers are supported?
Modern browsers like Chrome, Firefox, Edge, and Safari support the conversion tool. Make sure JavaScript is enabled and your browser is up-to-date.
Do I need to install anything?
No installation is required. The converter runs entirely in your browser using WebAssembly-based FFmpeg, making it fast and secure.
What about audio in the output?
GIF and PNG sequences do not include audio. WebM output preserves audio if present in the MP4 file.
Is the tool free to use?
Yes, this browser-based MP4 to WebM/GIF/PNG converter is completely free and does not require registration or downloads.
