How to optimize images for SEO and faster pages
Learn how image format, file size, dimensions and alt text affect website quality.
Choose the right file format
Use formats that fit the image type. Photos usually work well as JPG or WebP, while graphics and screenshots often work better as PNG or SVG.
Resize before uploading
Uploading a 4000 pixel image for a 900 pixel content area wastes bandwidth. Resize images to the size they actually need on the page.
Write useful alt text
Alt text should describe the image for people who cannot see it. Avoid keyword stuffing and focus on what the image communicates.
Compress responsibly
Heavy compression can create blurry details and artifacts. Always preview the final image on desktop and mobile before publishing.
Use descriptive filenames
A filename like `jpg-vs-png-example.png` is more useful than `IMG_4839.png`. Keep filenames readable and relevant.
Frequently asked questions
Do image filenames matter?
They can help organization and provide context, but they are only one small part of SEO.
Should every image have alt text?
Important content images should. Decorative images can use empty alt text.
What is the best image size?
It depends on layout, but images should not be much larger than their displayed size.
Need to convert a file?
Use Convertior tools after choosing the right format. Keep your original file until you have checked the converted result.
