What aspect ratios are supported?

Common presets include 16:9, 9:16, 1:1, 4:5, and 16:9 at 1280×720 for X. You can also set any custom width and height within the tool’s allowed range to create other ratios (e.g. 4:3).

Will resizing reduce video quality?

Scaling down always involves recompression; we encode with standard H.264 in-browser for a predictable result. Cropping in crop-to-fill doesn’t add blur — it removes edges after scaling. Scaling up can’t add real detail; avoid heavy upscales when possible.

What’s the best aspect ratio for Instagram?

It depends on placement: 9:16 for Reels/Stories, 1:1 for a classic feed grid, 4:5 for more vertical feed real estate, and 16:9 when you need widescreen. Match the placement you’re posting to.

Can I resize a video without cropping?

Yes. If the target aspect matches your source, the frame can scale without losing edges. If ratios differ, use fit-with-letterbox to avoid cropping (black bars may appear) instead of crop-to-fill.

What’s the maximum resolution I can export?

The tool supports large dimensions in principle, but practical limits are your device RAM, clip length, and browser stability. Very high resolutions and long 4K files take more time; close other heavy tabs and prefer desktop Chrome/Edge for difficult jobs.

What formats are supported?

You can import most formats the browser and our reader can demux (commonly MP4, MOV, WebM, MKV). Output is MP4 (H.264) for wide compatibility on phones, editors, and platforms.
