How JPEG to HEIC Conversion Works
JPEG is an image format: it uses lossy DCT compression that permanently discards fine pixel detail to achieve small file sizes, ideal for photographs. HEIC is an image format that applies H.265 (HEVC) intra-frame compression achieving roughly twice the efficiency of JPEG at equal visual quality, used natively by Apple devices. This conversion changes the file's encoding, compression method, and supported feature set. Colour profiles and orientation metadata are preserved in the output. Converting between these two formats is common when the source application does not support HEIC natively or when the target platform only accepts HEIC. 1converter processes this conversion server-side using open-source tools. Files are transferred over HTTPS, converted on secure cloud servers, and automatically deleted after 24 hours.

何时使用低/中质量:
- •网页上传和社交媒体分享
- •有大小限制的电子邮件附件
- •快速预览和缩略图
何时使用高/最高质量:
- •专业打印和出版
- •归档和长期存储
- •当质量比大小更重要时
图片提示:中等质量为照片提供最佳平衡。对于带文字的图形,使用高或最高质量以保持清晰度。
