Notes
Base64 encoding increases file size by about 1.37x, not recommended for large files; Data URL format can be used directly in CSS background-image, HTML img src, etc.; HEIC/HEIF images are not supported for browser preview but Base64 encoding still works; some browsers have Data URL length limits, large images are recommended to use Pure Base64 format
