Pro Tips
- Apply consistent sizing across all images in a series — uniformity signals professionalism and builds brand trust
- Save in the correct format — JPG for photos, PNG for graphics and transparency, WebP for optimal web performance
- Add alt text to all images on your website — this helps accessibility and search engine indexing
- Compress images before uploading to social platforms — platforms apply their own compression which compounds existing quality loss
- Create platform-specific versions rather than using one image everywhere — each platform has different display requirements
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.
