Create a compatible PNG file from your JPG image. The conversion happens entirely on your device. The tool decodes the JPG and creates a real PNG file while preserving the original pixel dimensions. Review the preview before downloading; the source file stays unchanged and the complete conversion runs locally in your browser.
Benefits of this conversion
- Create a real PNG file for a different app or workflow.
- Use a direct conversion with no unnecessary quality setting.
- Preview the converted JPG image and keep the source untouched.
How it works
- Choose a valid JPG file.
- Review the decoded image and its output dimensions.
- Convert, preview and download the PNG file.
JPG compared with PNG
JPG is a widely compatible, lossy photo format without transparency.
PNG uses lossless compression and can preserve transparent pixels, often with a larger file.
Quality, compression and transparency
PNG uses lossless compression and has no quality slider. It can preserve transparent pixels decoded from JPG; converting does not invent transparency that the source lacks. The result may be larger than a lossy file, while pixel dimensions remain unchanged.

Private by design
Your files stay on your device. Processing starts only when you choose an image, and nothing is stored on our servers.
Frequently asked questions
Are my images uploaded?
No. Processing happens locally in your browser, so your image files never leave your device.
Will converting to PNG change image quality?
PNG uses lossless encoding, so the conversion does not add compression artefacts.
What does JPG to PNG conversion create?
It decodes the source and creates a new, genuine PNG file.
Can I convert several files at once?
No. This converter processes one source image at a time.
How are quality and file size handled?
PNG uses lossless compression and has no quality slider. It can preserve transparent pixels decoded from JPG; converting does not invent transparency that the source lacks. The result may be larger than a lossy file, while pixel dimensions remain unchanged.
What happens to transparency?
PNG can retain transparent pixels when the decoded source contains them; conversion does not create missing transparency.
