Common Resizing Mistakes
- Stretching Images: Unlocking the aspect ratio and inputting custom numbers causes stretched or squished assets.
- Scaling Up Low Res Files: Resizing a small 200px file to 2000px wide will result in pixelation and severe blur.
- Skipping Compression: Resizing reducing physical dimensions helps, but always run files through a compressor to optimize bytes.
Pro Tips for Online Resizing
- Keep Originals Safe: Always keep a copy of your high-res originals, as downscaling permanently deletes pixel data.
- Match Screen Targets: Find out standard display pixels of your CMS columns and resize assets to match exactly.
- Use PNG for Logos: If resizing logos with sharp text and transparent borders, use PNG to prevent halos.
