Frequently Asked Questions
Crop or letterbox — which should I use?
Crop fills the whole 9:16 frame but cuts the sides, which works when the subject is centered. Letterbox keeps the entire picture and adds bars.
Can I change the bar color?
Yes. Pick any color for the bars before exporting.
Is my video uploaded?
No. Your file never leaves your device — processing runs locally in the browser using WebCodecs.
Is it free?
Yes. It is free with no account and no watermark.
