What is JPG to PNG Converter?
JPG to PNG Converter changes JPEG images into PNG files for editing, documents, and workflows that prefer lossless output. PNG preserves the decoded pixels without adding another lossy compression pass. The tool decodes the JPG in the browser and exports a PNG copy.
How does JPG to PNG Converter work?
This tool decodes the JPG source, draws it to a browser canvas, and encodes the canvas as PNG. PNG output keeps the decoded JPG pixels intact, but it cannot restore detail already lost during the original JPG compression.

- 2
JPG compression artifacts will remain in the PNG output since the decoded pixels are preserved.

For photographs where small file size matters, keeping the original JPG is often better.
Frequently Asked Questions
Will the quality change?
PNG uses lossless compression, so the decoded pixel data from the JPG is preserved exactly. No additional quality is lost, but JPG artifacts from the source remain.
Is my image uploaded to a server?
No. The JPG is decoded, converted, and exported in the browser.
What is the maximum file size?
The tool supports images up to 50MB. PNG output may be larger than the JPG source.
Does PNG support transparency?
Yes, PNG supports transparency, but JPG sources have no alpha channel, so the PNG output will be opaque.
Can I convert multiple images at once?
Yes. Upload multiple files and the tool converts all of them.
