What it does

Decodes PNG pixels and re-encodes them as JPG in your browser.

Worked example

Select a .png file to download a .jpg result.

The example demonstrates the operation. For file-based tools, results depend on the selected file and options.

How the result is produced

Decodes PNG pixels and re-encodes them as JPG in your browser.

Important limits

JPEG has no transparency; transparent pixels are flattened onto white. JPG, PNG, WebP and browser-decodable AVIF inputs (named converters require their stated source format); 25 MB and 24 megapixels maximum. Output is a single still frame; animation, source colour profiles and metadata are not preserved.

Choosing the next step

Use Resize when the dimensions are the problem, Compress when the bytes are the problem, and Metadata Remover when the file contains information you do not want to distribute. Format conversion is a separate choice: JPG is usually compact for photos, PNG keeps transparency, and WebP can be a useful modern compromise.
