How JPG to SVG 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 SVG produces a vector file that stores shapes, paths, and text as XML vector coordinates that scale to any resolution without quality loss. This traces the raster pixels into vector paths, making the result scalable without quality loss. Metadata such as creation date is preserved where the target format supports it; features the target format cannot represent are dropped. This makes SVG 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.
