Still have questions?
We got you!
How can I compress a video without losing quality?
Flixier uses cloud-powered compression algorithms that intelligently remove redundant data while preserving visual clarity. By using modern codecs like H.264 or HEVC, you can significantly reduce file size with results that remain "visually lossless" to the human eye.
What is the best video format for small file sizes?
For the best balance of quality and size, we recommend the MP4 format using the H.264 or H.265 (HEVC) codec. Flixier automatically converts older, bulkier formats like AVI or MOV into optimized MP4s during the compression process to ensure your files are lightweight and compatible with all devices.
How do I reduce video size for email or Discord?
Most email providers limit attachments to 25MB, while Discord has a 10MB limit for free users. Simply upload your video to Flixier, use our compression slider to target your specific file size, and download the optimized version ready for instant sharing.
Can I edit my video after compressing it?
Yes. Unlike simple utility tools, Flixier is a full AI video editor. After shrinking your file, you can move it directly to the timeline to trim unnecessary footage, add subtitles, or enhance the audio. You can complete your entire project in one tab without ever switching tools.
Does Flixier work on Mac, Windows, and Chromebook?
Because Flixier is browser-based and cloud-powered, it works on any operating system. You don’t need a high-end computer to compress large 4K videos; our servers handle the heavy lifting, allowing you to work smoothly on a laptop or even a mobile device.
Can I compress multiple videos at once?
Absolutely. You can upload multiple files to your library and compress them to fit your needs. Since your work is saved in the cloud, you can manage different versions and projects simultaneously without cluttering your local storage.
How do I remove background noise from a compressed video?
Smaller files often suffer from compressed audio artifacts. In Flixier, you can use our built-in AI Audio Enhancer to strip away background noise and improve speech clarity directly on the timeline, ensuring your lightweight video still sounds professional.
