How JPEG to WEBP Conversion Works
The JPEG Image format uses lossy DCT compression that permanently discards fine pixel detail to achieve small file sizes, ideal for photographs. Converting to WEBP produces an image file that supports both lossy and lossless encoding with transparency and animation, typically 25-35% smaller than equivalent JPEG or PNG files. This conversion changes the file's encoding, compression method, and supported feature set. The output is pixel-accurate: no further quality is lost beyond what the source already encoded. This makes WEBP the practical choice when the destination system requires it or when the target format offers better compatibility or compression. 1converter runs this conversion on the server: your file is uploaded encrypted over HTTPS, converted using trusted open-source libraries, and the output is held for 24 hours before automatic deletion.

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。
