How do I make images smaller for my website?

Lower the image quality slightly, cap its largest side at the size it is displayed and save it in a modern format such as WebP. Together these usually cut file size by 60-90% with no visible difference, which makes pages load noticeably faster. This compressor does all three in your browser.

How to compress images

Drop one or more images into the box (JPG, PNG, WebP or HEIC).
Choose Target size and a size in KB, or Quality and a percentage.
Optionally pick WebP and a largest side such as 1920 px.
Download the compressed images and replace the originals on your site.

Frequently Asked Questions

As a rule of thumb, keep large hero images under about 200 KB and content images under 100 KB, and never serve an image much wider than the space it fills - a 4000-pixel photo shown 800 pixels wide wastes most of its bytes.

No. Compression happens in your browser, so your photos never leave your device - useful for client work and private pictures.

WebP is usually 25-35% smaller at the same visual quality and works in every current browser, so it is the better choice for websites. Keep JPG when an older system you upload to does not accept WebP.
