Pro Tips
- Always work from the highest-resolution original — downsampling preserves quality, but upsampling cannot recover lost detail
- Use descriptive filenames for all images — search engines use filenames as ranking signals for image search
- Compress images to the smallest acceptable file size — smaller files load faster and improve SEO
- Test your images on both mobile and desktop before publishing — the same image can look different across screen sizes
- Keep original files in a separate folder — never overwrite originals with processed versions
Common Mistakes to Avoid
- Uploading images that are too small: Stretching a small image to fit a larger dimension reduces quality. Always start with an image at least as large as the target dimensions.
- Using the wrong file format: Using JPG for logos and graphics causes visible compression artefacts around edges. Use PNG for graphics, JPG for photography.
- Ignoring aspect ratio: Forcing an image into incorrect dimensions stretches or squashes it. Always maintain the correct aspect ratio for the platform.
- Over-compressing: Reducing quality too aggressively creates blocky artefacts. Aim for 75–85% JPG quality as a safe balance between file size and visual quality.
