How JPG to PPM Conversion Works
JPEG Image (JPG) uses lossy DCT compression that permanently discards fine pixel detail to achieve small file sizes, ideal for photographs. PPM file (PPM) stores data in the PPM format. This embeds the raster image inside a document container, fixing its dimensions on the page. 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 PPM file readable by any compatible application. 1converter handles JPG-to-PPM 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.

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。
为什么要将 JPG 转换为 PPM？
了解将 JPG 文件转换为 PPM 格式的优势
Removes JPEG’s lossy DCT artifacts by expanding pixels into raw RGB
Produces an uncompressed raster (PPM) that is ideal for image-processing pipelines
Keeps full-color RGB without JPEG chroma subsampling effects
Avoids re-compression cycles when running filters or computer-vision steps
Simplifies reading in tools that expect PPM’s straightforward header + pixel stream
