Choose video quality and file format
What each quality option in Lynx means, how file sizes are shown, and which video or audio format to choose, from MP4 to MP3, M4A, FLAC or WAV.
Quality
The card lists up to six of the best qualities the site offers, up to 4K (2160p) and 8K (4320p) when available, each with the size of the file. A small 60 next to a quality means 60 frames per second.
You get the quality you pick. If a video has 4K and you choose 4K, Lynx won’t give you 1080p instead.
Lynx Basic downloads 10 whole videos a day from web pages, up to 1080p; the sound of a whole video counts as one. Pro has no daily limit and every quality the site offers, up to 8K (all on during your 2-week trial).
Format
For video, MP4 is the default and plays everywhere. Lynx picks the H.264 version at the quality you chose, which QuickTime, Final Cut, Premiere and phones all open. Above 1080p, some sites offer only AV1. Lynx then saves the best MP4 available. If your editor imports it as sound only, here’s the fix. Clips are saved as H.264 by default.
For Audio only, choose:
| Format | Good for |
|---|---|
| MP3 | Any player, any device |
| M4A | Apple devices, slightly smaller for the same quality |
| FLAC | Lossless, smaller than WAV |
| WAV | Lossless, for editing |
File sizes
The sizes on the card match the file you get, give or take a little.
