Technical Considerations for High-Quality Visuals
Ensure your images have a high enough resolution to maintain clarity when displayed on various screen sizes. A common resolution for web images is 72 DPI.
Choose the appropriate image format based on the image content and desired quality. JPEG is suitable for photographs, while PNG is ideal for images with transparency or solid colors. WebP is a newer format that offers better compression than both JPEG and PNG.
Image Size and Compression
Optimize image size and compression to reduce file size without compromising quality. Tools like TinyPNG and Squoosh can help you achieve this.
Ensure your images are responsive and adapt to different screen sizes and resolutions. Use responsive image techniques like srcset and sizes attributes to deliver the optimal image for each device.
Write descriptive alt text for all images to improve accessibility for visually impaired users and to help search engines understand the content of your images.
