Which format should you use?
PNG keeps transparency and sharp edges, making it the right choice for logos, icons, and graphics with text. JPG produces smaller files for photos but doesn't support transparency and loses a small amount of detail. WebP is a newer format that generally gives the smallest file size at similar quality and supports transparency, making it a strong default for websites when browser support isn't a concern.
How this converter works
Your image is loaded into an in-browser canvas and re-exported in the format you select, entirely on your device. Converting to JPG will fill any transparent areas with white, since JPG doesn't support transparency.
Frequently asked questions
Why would I convert a PNG to JPG?
JPG files are typically much smaller than PNG for photographic images, which speeds up page loading and reduces storage or email attachment size. The trade-off is losing transparency support.
Why would I convert to WebP?
WebP often produces the smallest file size of the three formats at a similar visual quality, and unlike JPG it still supports transparency. The main reason not to use it is if you need compatibility with very old software that doesn't recognize the format.
What happens to transparent areas when converting to JPG?
Since JPG doesn't support transparency, any transparent areas are automatically filled with a white background during conversion so the image still displays correctly.
Does converting formats reduce image quality?
Converting to PNG is lossless and won't reduce quality. Converting to JPG or WebP applies compression, which can very slightly reduce quality depending on the encoding settings, though at default settings the difference is usually negligible.
