Guides
Everything we’ve learned shipping animated WebP, written down. These guides cover the full path from a raw video clip to a small, sharp, looping file: how WebP actually compares to GIF and MP4, which FFmpeg flags move the needle, what settings to use for email, hero sections, and thumbnails, and where animated WebP renders once it leaves your machine.
Each one is hand-written and benchmarked against real files — the numbers you’ll see come from converting actual clips, not spec sheets. They’re aimed at developers, designers, and marketers who want to understand the trade-offs rather than guess at a quality slider. New to the format? Start with WebP vs GIF for the fundamentals, then jump to optimal settings when you’re ready to convert. Updated when the landscape shifts.
