Frequently Asked Questions

Can GIF files contain audio?

No, the GIF format does not support audio. This tool converts your GIF to a video format (MP4 or WebM) that supports both animation and sound.

Which output format should I choose?

MP4 (H.264) works everywhere — all browsers, phones, and social media. WebM (VP9) produces smaller files with the same quality but may not work on older devices.

Is there a file size limit?

GIF files up to 100 MB and audio files up to 50 MB are supported. Since processing happens in your browser, larger files may take longer to encode.

How are my files processed?

Processing runs right in your browser: GIF frames and audio are assembled into video on your device through modern browser APIs (WebCodecs and Web Audio). Very old browsers fall back to a basic recording mode.

What audio formats are supported?

MP3, WAV, OGG, M4A, FLAC, and AAC. You can also record audio directly from your microphone.

Can I adjust the GIF speed to match my audio?

Yes. Use the sync modes to automatically match durations, or adjust GIF speed manually in the advanced settings (0.25x to 4x).
