Pro Tips for Image Resizing
- Resize Before Compressing: Always resize your image to the correct display dimensions FIRST, then run it through our Image Compressor. Compressing a 4000px image when you only need 500px is massive overkill.
- Never Scale Up: Increasing an image's dimensions (upscaling) will make it blurry and pixelated. If you need a larger image, look for a higher-resolution source.
- Use WebP for Web: After resizing, consider converting to WebP format — it offers 30% smaller file sizes than JPG at the same visual quality, which is ideal for websites.
