About JPG en PNG

Utilisez cet outil directement dans votre navigateur avec des options claires et un traitement privé lorsque disponible. Use it when you need the result without the overhead of opening a larger application. For anything important, compare the output with your source and keep the original until you are satisfied with the result.

Editorial note

Use PNG for compatibility or transparency—not as a magic quality upgrade

Convertiring a JPEG to PNG is useful when another application expects PNG, when you need to continue editing in a lossless format, or when a workflow specifically requires a .png file. The conversion preserves the pixels that exist in the JPEG; it cannot recover detail already discarded by JPEG compression.

Compare file size after conversion. Photographs often become much larger as PNG files, so converting simply because “PNG is higher quality” can create a heavier file without adding visible information.

A realistic example

A design tool that only accepts PNG can use a converted product photo, but keep the original JPEG too so you are not forced to use the larger PNG everywhere.

When this tool is not the right fit

If your real goal is a smaller photographic file, compression or WebP may make more sense than JPG-to-PNG conversion.

Example

Example: convert a JPG photo to PNG when you need a lossless PNG file for editing, graphics work, or a workflow that requires PNG input.
