Image compression with format and quality controls
Image compression reduces file size while retaining enough quality for the destination. The right balance differs for photographs, screenshots, text-heavy graphics and assets that require transparency.
- When it is useful
- Compare original and output sizes and choose PNG, JPG or WebP. JPG and WebP include a quality control for preparing images for websites, email or documents.
- Privacy and scope
- The file is decoded and generated again in the browser rather than uploaded to a compression server. The resulting download stays under the user's device control.
- Result limitations
- JPG removes transparency and can introduce artifacts; PNG preserves sharp edges and transparency but may be larger for photos; WebP often balances both. Always inspect small text, gradients and edges.
