Frequently asked questions

Everything worth knowing before you crop a video here.

help

Does cropping reduce video quality?

Cropping itself only changes which part of the frame is kept — it's a re-encode of just that region, at a higher-fidelity preset than a plain format conversion since you already have the file in this format and are only editing it, not converting it from scratch.

help

Why did my crop width or height change slightly?

Standard video codecs need even width and height for their color format — an odd number gets rounded down by 1 pixel automatically so the export never fails over something that small. The panel shows you the rounded size live, before you export.

help

Can I change the output format while cropping?

Yes — the optional Save As dropdown re-encodes into MP4, MOV, AVI, MKV, or WEBM in the same pass, instead of needing a second trip through a separate converter.

help

Can I lock the crop box to an exact size, like 1920×1080?

Yes — the Aspect Ratio dropdown includes exact pixel presets (not just ratios) for common social media and screen sizes. Picking one sets that exact size, centered on your current crop, and keeps it locked as you fine-tune the position.

help

What's the largest video I can crop?

Videos up to 1 GB are supported.
