Convert JPG to PNG Online
Converting JPG to PNG takes one upload and one click. QuickPixel decodes your image on a canvas inside your browser and re-encodes it as PNG, so the result downloads instantly with no server round-trip.
Converting to PNG adds support for a transparent background and keeps every pixel lossless, at the cost of a larger file than the original JPG.
You can also batch-convert several files at once and download them individually or together as a ZIP, or jump to the Compress tab afterward to shrink the result even further.
FAQ
Frequently asked questions
Is this tool free?
Yes, completely free with no limits and no registration required.
Are my images uploaded to a server?
No. Processing happens entirely in your browser using JavaScript — your files never leave your device.
Will converting JPG to PNG change the image quality?
Converting between formats re-encodes the pixel data, so a quality slider is available when the output is JPG or WebP; PNG output is always lossless.
Does this work on my phone?
Yes, it works in any modern mobile browser on iOS and Android, no app required.
Can I process multiple images at once?
Yes. Upload several files and download them individually or together as a ZIP.
