How to reduce image size

Which settings should I use?

- Websites: WebP, quality 75–80, 1920 px.
- Print or archives: keep the original; compress only copies.
FAQ
Is compression lossless?
No. JPG and WebP are lossy: smaller files mean slightly less detail. At quality 75–85 the difference is rarely visible.
Why did my file get bigger?
An already well-compressed image can grow when re-saved at high quality. Lower the quality or the maximum size.
Are images uploaded?
No. Compression runs in your browser.
