Compress image
Shrink JPG, PNG and WebP files for faster pages — set a quality or a target size in KB.
Questions
- Are my images uploaded anywhere?
- No. Every image is processed inside your browser and never leaves your device, so it's safe for client work and unreleased designs.
- What format should I use for my website?
- WebP gives roughly 25–35% smaller files than JPG at the same quality and works in every modern browser. AVIF is smaller still but slower to encode.
- How big should website images be?
- Aim for under 200 KB for hero images and under 100 KB for content images. Setting a max width of 1920px (or 1200px for blog images) helps most.
