Pro Tips for Best Results
- Match your image quality settings to the content type — 75–85% JPG quality is ideal for photographs, while PNG should be used at full quality for graphics
- Consider the viewing context when choosing dimensions — mobile screens show images at half the pixel density of desktop, so test at both sizes
- Remove metadata (EXIF data) from images before publishing — this reduces file size slightly and protects location data embedded in photos taken on smartphones
- Schedule image updates regularly — platform requirements change, and an image that meets specifications today may need updating after a platform redesign
- Use the Convert tool at imgresizr.com to change image formats without re-encoding multiple times — each re-encoding cycle reduces quality slightly
Common Mistakes to Avoid
- Not checking images on mobile: Images that look sharp on a desktop monitor often appear different on mobile screens. Always test on a smartphone before publishing, particularly for profile pictures and thumbnails.
- Overwriting the original file: Always save processed files with a new filename or to a new folder. If you make a mistake during processing, you need the original file to start again — and overwriting makes this impossible.
- Skipping alt text on web images: Missing alt text harms accessibility for users with visual impairments and reduces search engine visibility. Every image on a website should have a descriptive, keyword-relevant alt text attribute.
- Using one image across all platforms: Each platform has different aspect ratio requirements and display contexts. An image cropped for Instagram will look wrong on LinkedIn. Create platform-specific versions for professional results.
