How JPG to PDB 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 PDB produces a document file that stores data in the PDB 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. This makes PDB the practical choice when the destination system requires it or when the original format is not supported by the target application. 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.
