PNG to JPG, explained
Turn a PNG photo or screenshot into a JPG for an upload form, email attachment or application that accepts JPEG files. By default this conversion keeps the pixel dimensions and fills transparent areas with white. Choose JPEG quality above Advanced Settings; expand the settings to resize or change the background. Keep the PNG original when transparency or exact graphic edges matter.
Choose your PNG files. A preview confirms that each image can be read.
Keep JPG selected and start with quality 90. Lower it if you need a smaller download.
Convert, inspect fine details, and download individual JPGs or the complete batch as a ZIP.
When changing PNG to JPG helps
A photograph saved as PNG can be inconvenient for a form that expects a JPEG or limits attachment size. JPG gives you a quality control to trade some image detail for compression. A logo, line drawing or screenshot full of small text may be better left as PNG; the best choice depends on the picture, not just its extension.
What happens to a transparent background?
JPEG cannot store an alpha channel. FormatPlease fills transparent and partially transparent pixels with your selected background before encoding (white by default). Set White, Black or a custom hex color in Advanced Settings. Preview the result on the background where you intend to use it. If the background must remain transparent, choose PNG or WEBP instead.
Choosing JPG quality for a photo
The initial quality is 90 out of 100. For a photo intended for a web page, you can try 80–90 and compare the download at its actual display size. Look closely at hair, foliage, gradients and text. These settings are starting points for inspection, not guaranteed visual-quality or file-size targets.
Why the new file is not always smaller
A PNG with a few flat colors may already compress efficiently. JPEG overhead and the chosen quality can make its replacement larger. The results list shows the output size so you can make a real comparison. Optional resize in Advanced Settings can reduce pixel dimensions, but neither resize nor quality guarantees a particular kilobyte limit.
Avoid repeated lossy conversions
Every fresh JPEG encode can introduce additional changes. If the first result is too small or visibly damaged, adjust quality and convert from the original PNG again. Do not use the downloaded JPEG as the source for repeated experiments when the original is available. Metadata is not copied to the output.
