Convert
Turn a PNG into a much smaller JPEG. Because JPEG has no transparency, any transparent areas are filled with a background colour you choose - white by default.
This tool accepts PNG files. Everything is decoded by your own browser, so the formats available depend on what your browser can open - which for HEIC in particular varies between Safari and other browsers.
Because the image is rebuilt from raw pixels, EXIF metadata such as camera details, timestamps and GPS coordinates does not carry into the result. Orientation is applied to the pixels first, so photographs stay the right way up. Embedded colour profiles are also dropped and the output is saved as sRGB, which can shift colours slightly in wide-gamut photographs. Animated files are refused rather than being flattened to a single frame.
No. Your PNG is converted on your own device. That matters for screenshots in particular, which often contain information you would not want passing through someone else's server.
Yes, free and unlimited, with no account required and nothing added to the converted image.
JPEG has no alpha channel, so transparency has to become a solid colour. This tool paints the chosen background behind the image before encoding - white by default. Without that step transparent pixels would come out black.
For photographs saved as PNG the saving is dramatic, often 80-90%. For flat graphics, logos and screenshots the difference is smaller, and JPEG can even look worse because it blurs sharp edges. Those are better kept as PNG or converted to WebP.
Yes, JPEG is lossy. At quality 85 or above the difference is very hard to see on photographs. On text, screenshots and line art you may notice halos around sharp edges at any quality.
