Visual content accounts for more than half of the data downloaded on an average webpage. Proper optimization ensures fast rendering on mobile devices while helping search engines understand your visual assets.
Why next-gen formats matter (WebP and AVIF)
Legacy formats such as JPEG and PNG produce unnecessarily large file sizes. Modern formats like WebP offer superior lossless and lossy compression, reducing file weights by 25% to 35% without visible quality loss.
Converting hero banners, product images, and article illustrations to WebP improves Core Web Vitals—specifically Largest Contentful Paint (LCP).
Writing descriptive Alt text for search and accessibility
Alternative text (the alt attribute) serves two crucial functions: it enables screen readers to describe images to visually impaired visitors, and it provides search engines with context regarding image content.
- Be descriptive and specific: Describe the subject, action, and context clearly.
- Avoid keyword stuffing: Never cram irrelevant keywords into alt attributes.
- Mark decorative images: Use an empty
alt=""for decorative borders or abstract backgrounds so assistive technology skips them.
Stripping sensitive EXIF metadata before publishing
Photos taken with mobile phones and digital cameras frequently embed sensitive metadata, including exact GPS coordinates, camera serial numbers, and capture timestamps. Using a privacy-focused local tool like GeckoShareSafe allows you to remove this metadata before publishing, protecting user privacy.
