Why use Crop Video Aspect Ratio?
- Batch processing helps when the same operation has to be repeated across a folder or a set of client files.
- The operation is useful when the desired change is smaller than a full format conversion.
- The queue makes it practical to handle several files with one consistent setting.
- Use crop video aspect ratio when the source file is already in a suitable format but needs a focused operation rather than a full format change.
What changes?
Crop to 9:16 or other. Complex or encrypted files may need manual review after the operation completes.

The file is processed on the server because the conversion requires a server-side engine or a utility operation. The operation is selected by the tool and is not a generic pair conversion.
- Server processing accepts files up to 100 MB; very large batches may need to be split.
- Complex files may take longer and can hit processing time limits.
- Encrypted, damaged, or unusual VIDEO/* files may fail or need manual review.
Platform compatibility
The output format is supported by all current major browsers for common codecs. Desktop and mobile compatibility still depends on the specific application, so test critical files.
When not to convert
- Avoid repeated lossy conversions when quality matters; start from the highest-quality source available.
- If the file contains sensitive data, review the processing model before uploading it to a server.
- Do not convert when the original VIDEO/* must remain the only editable or archival copy.
