Frequently asked
- Is PNG to WebP lossless?
- Fileroom encodes WebP with a quality setting, so it's lossy — but at high quality, screenshots and graphics look the same while taking far less space.
- Should I use WebP or JPEG for screenshots?
- WebP. It handles text and flat colors better than JPEG, which tends to blur sharp edges.
