About JPG to PNG Converter
The JPG to PNG Converter transforms your JPEG images into PNG format entirely inside your browser. Just drag and drop your files and download the results.
Why choose PNG?
JPEG compression is lossy: every time you edit and re-save a JPG, quality degrades slightly. PNG uses lossless compression, preserving every pixel exactly. This makes it the preferred format for graphics, logos, screenshots, and any image destined for further editing. PNG also supports an alpha channel for transparency, which JPEG cannot.
How it works
When you upload a JPG, the tool draws it onto an invisible HTML5 Canvas element and then exports the canvas as a PNG. The browser handles the encoding natively, ensuring accurate color reproduction. You see a side-by-side preview with the original and converted file sizes so you know exactly what to expect.
Batch conversion
Need to convert several images? Select multiple files at once or drag a batch into the drop zone. Each file is processed independently and shown with its own preview and download button, so you can grab them one by one or convert your entire set in moments.
Everything stays on your device. The tool works offline once the page is loaded, runs on any modern browser, and requires no account or installation.
Frequently Asked Questions
Why convert JPG to PNG?
PNG uses lossless compression, so converting preserves every pixel without further quality loss. PNG also supports transparency. If you need a clean image for a logo, graphic overlay, or any use case where artifacts are unacceptable, PNG is the better format.
Does the conversion happen on a server?
No. The entire conversion runs in your browser using the HTML5 Canvas API. Your images are never uploaded anywhere, which means faster processing and complete privacy.
Can I convert multiple images at once?
Yes. The batch mode lets you drag and drop or select several JPG files at once. Each image is converted independently and can be downloaded individually.
Will the file size increase?
Usually yes. PNG uses lossless compression while JPG is lossy, so the resulting PNG file is often larger. The tradeoff is zero quality loss and support for transparency if you add it later in an editor.
