How to Convert a JPG to PNG

- The converter reads the file locally and redraws it onto a canvas — nothing is uploaded to a server.
- A PNG version renders automatically; check the JPG Size, PNG Size, and Dimensions stats to compare.
- Click "Download PNG" to save the converted file to your device.
Frequently Asked Questions
Why is my new PNG file larger than the original JPG?
PNG is a lossless format, so it stores every pixel exactly instead of throwing away detail the way JPEG's lossy compression does. For photos with lots of color detail, that usually means a noticeably bigger file than the source JPG.
Does converting to PNG lose any image quality?
No - going from JPG to PNG can't add quality back that the original JPEG compression already removed, but this converter draws the image onto a canvas and re-encodes it losslessly, so no further quality is lost in the conversion itself.
Will my photo's EXIF data (camera info, date, GPS) carry over to the PNG?
No. The conversion draws the image onto an HTML canvas and exports fresh pixel data, which strips EXIF metadata in the process - the PNG will contain only the image itself, no camera or location tags.
Is my JPG uploaded to a server during conversion?
No. The whole process - reading the file, drawing it to a canvas, and encoding the PNG - happens in your browser using JavaScript's FileReader and Canvas APIs. The image data never leaves your device.
Can I convert multiple JPGs at once?
Not currently - this tool handles one image at a time. Upload a new JPG to replace the current preview and start another conversion.
