JPG to PNG Converter

Convert JPG files to PNG in your browser, without uploading or signing up.

How to use

1. Save JPEG photos as PNG for compatibility with tools that require lossless PNG containers.
2. Select your files. Adjust image quality or the background color when supported. Press Convert, then download each result or the entire ZIP.

About these formats

JPG stores photos with adjustable lossy compression, and does not support transparency. PNG preserves pixel detail and alpha transparency using lossless compression. Conversion cannot restore image detail already removed by JPEG compression.

Browser limitations

The selected browser must decode JPG and encode PNG. Large images may exceed available device memory.

Frequently asked questions

Are files uploaded?

No. Image decoding and re-encoding run locally in your browser.

Can I convert multiple images?

Yes. Add multiple files and download all finished results in one ZIP.

Will the quality change?

PNG export stores the decoded pixels losslessly, but does not restore details lost earlier.
