JPG 到 MOBI 转换器 — 快速免费

JPEG Image (JPG) uses lossy DCT compression that permanently discards fine pixel detail to achieve small file sizes, ideal for photographs. Mobipocket Ebook (MOBI) stores reflowable text in the Mobipocket format originally designed for Amazon Kindle devices, now largely superseded by KFX. This conversion changes the file's encoding, compression method, and supported feature set. Metadata such as creation date is preserved where the target format supports it; features the target format cannot represent are dropped. The result is a standard MOBI file readable by any compatible application. 1converter handles JPG-to-MOBI conversion server-side: files are uploaded over HTTPS, processed on isolated cloud infrastructure, and the converted output is available for download for 24 hours before automatic deletion. No account is required for standard conversions.
