Convert JPEG to PNG Online
Converting a JPEG to PNG is useful when you need a lossless copy of an image, want to add a transparent background, or need to apply further edits without accumulating JPEG compression artefacts. PNG uses lossless compression, so every pixel is preserved exactly as-is during the conversion. This tool converts JPEG files to PNG in your browser without uploading anything to a server. The resulting PNG will be larger than the original JPEG because PNG stores more information, but it is suitable for use in design workflows, icon creation, or anywhere transparency support is required. Multiple conversions can be done quickly without any software installation.
FAQ
- Does converting JPEG to PNG improve quality?
- No. Converting JPEG to PNG creates a lossless copy of the already-compressed JPEG. Original JPEG artefacts are preserved, not removed. For higher quality, start from the original uncompressed source.
- Why is the PNG file larger than the JPEG?
- PNG uses lossless compression which stores every pixel precisely, resulting in larger files than JPEG's lossy compression for photographs.
- Can I add transparency after converting?
- Converting to PNG gives you a format that supports transparency, but the tool does not automatically make any pixels transparent. Use an image editor to remove the background after converting.
