How this calculator works
This tool reads your JPG image in the browser, redraws it on a canvas, and exports a PNG version without needing a server upload.
PNG can be useful when you want a widely supported image format without JPG-style compression artifacts in the exported file.
What the result means
A successful result means a PNG version of your image is ready to download. The result box shows the output dimensions and file size.
That gives you a quick way to compare whether PNG is practical for your workflow.
Important limitations
Converting JPG to PNG does not restore detail already lost to JPEG compression. It changes the container format, not the history of the source image.
PNG files can also become larger than JPG files, especially for photo-heavy images.
When to use this calculator
Use JPG to PNG when you need PNG output for compatibility, workflow consistency, or image handling that fits better with the rest of your project.

FAQs

Does converting JPG to PNG improve quality?
It does not restore lost detail. It mainly changes the output format.
Why can PNG files be larger than JPG files?
PNG often stores image data differently, and photo-style images can end up much larger than their JPG versions.
Can I use this on a phone?
Yes. The tool is built as a browser-based mobile-friendly workflow.
Is this a photo-editing tool?
No. It is a focused browser-based format conversion utility.
