How to compress images for websites and email
Large images can slow page loading and make email attachments difficult to send. Compression can help, but the best settings depend on the image.
Step-by-step advice
For photographs, start with a moderate quality setting and compare the result at its intended display size. Resize overly large images before compressing if they will never be shown at full resolution. For screenshots, illustrations, and images containing text, check that edges remain sharp. Choose a format supported by the destination service.
What to watch for
Smaller files are not automatically better if important details become unreadable. Save your original before replacing an image.
