About the source format (JPG)
JPG (JPEG) dominates digital photography. DCT lossy compression yields small files at good visual quality — the web standard since the 90s. Compression type: Lossy — smaller files, but data is lost on each conversion. On Toolando.tech you can convert JPG files to many other formats and back — no software to install, directly in your browser. Files are processed securely and deleted after conversion.
