Convert PNG to JPEG Online
PNG and JPEG serve different purposes: PNG is lossless and supports transparency, while JPEG uses lossy compression that dramatically reduces file sizes for photographs and complex images. Converting PNG to JPEG is a common step when optimising images for websites, email attachments, or apps where storage and bandwidth matter. This tool converts your PNG to JPEG directly in the browser, letting you control the compression quality so you can balance sharpness against file size. Transparency in the PNG is replaced with a white background during conversion, as JPEG does not support alpha channels. No files are uploaded — processing happens entirely on your device.
FAQ
- Why convert PNG to JPEG?
- JPEG files are typically 60–80% smaller than equivalent PNGs for photographs. Use JPEG when you do not need transparency and want to reduce file size for web delivery or sharing.
- What happens to transparency when converting PNG to JPEG?
- JPEG does not support transparency, so transparent areas in the PNG are filled with a solid background colour (white by default) during conversion.
- Will converting PNG to JPEG lose quality?
- JPEG uses lossy compression, so some quality is lost. At high quality settings (85–95%) the difference is barely noticeable, but at low settings artefacts become visible around edges and fine details.
