Frequently Asked Questions
Everything you need to know about compressing videos on ILoveFiles.
Which video formats can I compress with this tool?
This tool fully supports MP4, WebM, MOV, AVI, and MKV video formats.
Are my videos uploaded to a cloud server?
No! All video processing and compression happen 100% locally inside your web browser using FFmpeg WebAssembly technology. Your private videos never leave your device.
How does resolution scaling affect file size?
Downscaling resolution (e.g., from 1080p to 720p or 480p) reduces total pixel count significantly, yielding drastically smaller video file sizes.
How can I compress videos without losing visual quality?
You can adjust the target quality or bitrate settings before compressing. Keeping the original resolution while slightly lowering the video bitrate significantly reduces file size with imperceptible quality loss.
Does compressing a video reduce its resolution?
Not automatically. You can choose to maintain the original resolution (1080p, 4K, etc.) or downscale it to 720p or 480p if you need extreme file size reduction for email or messaging apps.
Can I batch compress multiple videos at once on iLoveFiles?
Yes! You can drag and drop multiple video files simultaneously, apply uniform compression settings, and process them all directly in your browser.
Why is client-side browser video compression safer?
Client-side processing guarantees complete privacy because your private videos are never sent over the internet or saved to remote cloud servers.
Which video format yields the smallest file size?
MP4 (H.264/AAC) and WebM (VP9/Opus) formats offer the best compression efficiency, maintaining high clarity at smaller file sizes compared to AVI or MOV.
Does this free video compressor work on mobile devices?
Yes, iLoveFiles Video Compressor is fully responsive and works seamlessly across Android smartphones, iPhones, iPads, PCs, and Macs using modern browsers like Chrome, Safari, or Firefox.
Is there any restriction on video size or usage limit?
