Tips for Best Quality
- Always start from the original high-resolution image — never upscale a previously shrunk image.
- Enable Maintain Aspect Ratio to avoid stretching or distortion.
- Use WebP for web use — same quality at a smaller file size.
- For print, ensure at least 300 DPI resolution.
- For web, 72-96 DPI is sufficient and greatly reduces file size.
