Convert to MP4

Make an MP4 when your browser supports H.264 export. Compress, resize, convert to MP4 where supported, and make animated GIFs without uploading.

What happens to audio during video conversion? Video exports keep audio when the selected output format supports it. GIF does not support audio, so GIF conversions are silent.

Frequently Asked Questions

Are my files uploaded to your servers?

No. SizeDrop is 100% on-device. All image and video transformations happen inside your web browser using HTML5 Canvas, WebAssembly, and native media decoders. Your files never touch any external server.

When will the Android app launch on Google Play?

The companion app is in active testing. Leave your email via the form above with topic "Android Early Access" to be added to the internal testing track.
