About the JPG to PNG Converter
The JPG to PNG Converter turns JPEG (JPG) images into Portable Network Graphics (PNG) files right inside your web browser. Convert to PNG when you need lossless quality for further editing, want to add transparency later, or an upload form requires PNG.
JPG (or JPEG) is the most widely used photo format in the world. It uses lossy compression to keep photographs small, which makes it perfect for cameras, websites and messaging, but it cannot store transparent areas and loses a little quality every time it is re-saved.
PNG is a lossless format that preserves every pixel exactly and supports full transparency. It is ideal for logos, icons, screenshots, illustrations and images with text, although photos saved as PNG are usually much larger than JPG.
PNG is lossless, so the converted file keeps every pixel of the decoded JPG image without adding any new compression artifacts. JPG images have no transparency, so the result looks exactly like the original. You can convert dozens of images at once, optionally limit the maximum width to shrink large photos, and download everything as a single ZIP file. Because the conversion runs locally on your device, your pictures are never uploaded to a server.
How to use the JPG to PNG Converter
- Drop your JPG files into the upload area, click to browse, or paste an image.
- Adjust the quality or maximum width if needed.
- Wait a moment while each image is converted to PNG on your device.
- Download files individually or click Download all (ZIP).
