How this estimate works
No source media is uploaded by these calculators. A selected file is used only for local metadata inspection.
- All calculations run locally in the browser.
- Bitrate and file size are estimates; variable bitrate and container overhead can change exports.
- Safe zones are conservative review aids, not platform guarantees.

Frequently asked questions
What is an aspect ratio?
It is the proportional relationship between a video frame width and height, such as 16:9 or 9:16.
Does this change my file?
No. It is a deterministic planning calculator. Use a browser tool or Studio to transform a file.
Need to edit the file, not just inspect it?
After the result, continue into a focused local tool or the full Studio when the job needs a timeline.
