JPG to PNG conversion
Use this JPG to PNG converter when an app, website, or design workflow requires a PNG file. The conversion is local and lossless after decoding, but it cannot restore detail already removed by JPG compression or create real transparency automatically.
Why convert JPG to PNG?
Use the right format
PNG is a practical choice for editing workflows, screenshots, and apps that require PNG. Converting creates a new file and leaves your original JPG unchanged.
Know the tradeoff
JPG uses lossy compression; PNG uses lossless compression. JPEG compression artifacts remain in the PNG output.

JPG vs PNG
| Format | Best for | Compression | Transparency | Animation |
|---|---|---|---|---|
| JPG | photographs, email attachments, and broadly compatible web images | Lossy | No | No |
| PNG | graphics, screenshots, logos, and images that need transparency | Lossless | Yes | APNG in compatible software |
JPG, also called JPEG, uses lossy compression to make photographs and other detailed images smaller and widely compatible. PNG is a lossless image format that keeps sharp edges and transparent pixels, making it a strong choice for graphics, screenshots, logos, and interface assets.
