About JPG to PNG Conversion

Why Convert to PNG?

PNG uses lossless compression meaning every pixel is preserved exactly. This makes it ideal for images that need to be edited multiple times or images with sharp edges like logos and text.

Transparency Support

Unlike JPG, PNG supports an alpha channel for transparency. When converting from JPG (which has no alpha), you can choose a background fill color or leave it white for full opacity.

File Size Trade-off

PNG files are generally 2–5× larger than equivalent JPG files. For web use, consider WebP which offers both lossless and lossy compression with smaller file sizes. Use PNG when quality is critical.

Batch Processing

This tool supports converting up to 50 images at once. All processing happens in your browser using the HTML5 Canvas API. The ZIP download bundles all converted PNGs into one file.
