Does resizing make my video file smaller?

Not necessarily. Resizing changes the picture dimensions. The new file size also depends on the duration, content and export codec; this tool does not guarantee compression.

Which files can I use?

Support depends on the codecs inside a file and your browser, not just its MP4, MOV or WebM extension. Unsupported files are rejected with an explanation. Sources can be up to 10 minutes long, with a pixel count up to 3840 × 2160 and no edge over 4096 pixels. Audio must be mono or stereo.

What are the export limits?

Open up to 8 files including music, totaling no more than 200 MiB. The edited sequence can be up to 2 minutes long. Video exports use 30 frames per second and 1280 × 720, 720 × 1280 or 720 × 720 pixels. MP4 and WebM availability depends on your browser’s codec support. Exports are limited to 100 MiB. Larger tasks can reach your device’s memory limits.

How it works

Open your video and choose one of the three aspect ratios.
Choose fit or centered crop for each clip.
Preview the layout and download the resized video.

Landscape exports at 1280×720, portrait at 720×1280 and square at 720×720. Choose the shape that fits where the video will appear, then check text and faces near the edges. Smaller sources can be enlarged, but resizing cannot add missing detail.

Good to know

Three output presets are available. Custom pixel dimensions, 4K exports and automatic quality enhancement are not included.

Your original files stay unchanged. Download your result before closing or reloading the page; your project is not saved.
