Frequently asked questions
Answers about privacy, limits, and how this free free shorts / reels aspect cropper works.
Do you upload my video?
No. Cropping and export run entirely in your browser with Canvas and MediaRecorder.
Why WebM instead of MP4?
Browsers reliably record WebM via MediaRecorder without a server. MP4 remux needs heavier local tooling.
What are the limits?
Max 100 MB file size and 120 seconds of export to keep tabs responsive.
Is the Shorts cropper free?
Yes. Free with no signup or watermark.
Need zooms and captions too?
