Frequently Asked Questions

Is this video compressor free?

Yes. You can compress videos for free without signup, software installation, paid APIs, or watermarks.

Does compression change video quality?

Only when you choose a compression preset or custom setting. Convertr keeps the original resolution by default unless you select a resize option.

Can I choose a target file size?

Yes, custom mode can aim for an approximate target size when the requested size is technically feasible for the video duration. Exact output size is not guaranteed.

What is the maximum upload size?

The upload limit is 1 GB, matching the rest of Convertr. Full-resolution videos are supported when the file is within that limit.
