About this tool
JPG to PNG is for workflows that require PNG. It preserves dimensions and does not claim compression savings when the output grows — common when leaving lossy JPEG for lossless PNG.
Frequently asked questions
- Are my images uploaded?
- No. Conversion runs entirely in your browser using canvas APIs. Files are not uploaded.
- Why is my PNG larger?
- JPG uses lossy compression suited to photos. PNG is lossless and often larger for the same pixels. That is expected for format conversion, not a compression failure.
- Does this add transparency?
- No. JPG has no alpha channel, so the PNG is fully opaque at the same dimensions.
