Frequently asked questions

Does cropping lower the quality?

The picture is re-encoded at high quality, and cropping keeps the original pixels of the part you keep.

Can I crop a custom area?

Not yet. Pick a shape and a position; the largest possible area of that shape is kept.

Is there a file size limit?

Files up to 100 MB. Longer or larger videos may take up to a few minutes to process.
