How to compress images for a faster website

Large images are one of the most common reasons web pages load slowly. Two things help most: serving the right size and using an efficient format.

Steps

1. Open the Image Compressor & Converter.
2. Drop all your images at once.
3. Choose WebP for the smallest files with broad browser support, or JPEG for photos where WebP isn't accepted.
4. Set a maximum width — for most blog content 1600 px is plenty.
5. Adjust quality (around 75–85 is a good starting point) and download everything as a zip.

Rules of thumb

• Photos: WebP or JPEG. PNG photos are usually far larger than they need to be.
• Logos, icons, screenshots with text: PNG or WebP (lossless). SVG is best for logos if you have it.
• Resize before compressing. A 4000 px photo shown at 800 px wastes bandwidth no matter how well it's compressed. The Image Resizer has presets for social sizes.

Privacy

All compression runs in your browser, so unreleased product shots or client images never leave your machine.
