Frequently Asked Questions

Will compressing AVI reduce quality?
Our compressor uses smart bitrate allocation to minimise visible quality loss. For most files, the difference is imperceptible at normal viewing sizes.
Can I set a specific target file size?
Yes. You can enter a custom target size or select a platform preset and the compressor will aim for the best quality within that limit.
Is AVI compression free?
Yes, completely free. No account, no watermarks, no limits on how many files you compress.
What size does Email require?
Email enforces specific upload size limits. Our platform preset automatically applies the right settings so your file uploads without rejection.
Is it safe to upload my AVI file?
All uploads are encrypted with HTTPS and your files are deleted from our servers immediately after the compressed version is ready for download.
