Tips for Best Instagram Images
- Use high resolution source images. Start with the highest quality image possible; resizing up reduces quality.
- Export as JPG for photos. JPG offers the best quality-to-size ratio; keep quality at 80-90%.
- Export as PNG for graphics. Logos and graphics with text look sharper in PNG format.
- File size limit: Instagram recommends under 8MB per image. Use image compression if needed.
