Image Resizing Guide for Web, Social, and Documents
Resizing changes image dimensions, while compression changes file size. For best performance, do both: resize oversized photos to the display size you actually need, then compress the final image.
Use smaller dimensions for thumbnails, medium dimensions for blog images, and larger dimensions only when users need to inspect detail. Uploading a 4000 pixel photo for a 600 pixel card wastes bandwidth and can slow down mobile visitors.
Best use cases
- Resize profile images and avatars
- Prepare blog feature images
- Create thumbnails for galleries
- Fit images into document upload limits
Pro tips
- Keep aspect ratio locked when possible
- Resize before compressing
- Use descriptive file names for SEO
- Avoid stretching small images upward
