Convert Video to 1:1

Prepare a 1:1 MP4 with the real aspect-ratio converter already set to this frame. Choose whether to crop the source or retain it with padding; the export is re-encoded, not a lossless container change.

Frame the source for 1:1

A square frame can balance a wide and a tall source, but either source may require cropping or borders. Compare both modes using a short test clip before preparing a square animation or feed asset.

Choose crop or padding deliberately

Upload an H.264 MP4, choose crop or pad and decide whether to keep supported AAC audio. Export and play the new MP4 before using it. Output dimensions follow the selected aspect ratio and bounded source geometry; this page does not promise a fixed 1080-pixel export.

Keep clips within local processing limits

Use a clip up to 50 MiB, 30 seconds, 30 fps and 720p-equivalent resolution, with no source edge above 1280px. The video engine loads on demand and processing stays local. Unsupported codecs produce errors; mute can bypass unsupported audio. Re-encoding may reduce quality and takes time on mobile devices.

Common questions

Does padding keep the complete frame?

Yes, pad mode fits the source inside the selected frame and fills unused space. Crop mode removes overflow from the center.

Can this turn a horizontal clip into a vertical one without losing any pixels?

Choose padding to retain the visible frame. The output is still re-encoded and is not a lossless copy.
