Convert a JPEG Photo Into a PNG

This converter turns your JPEG into a PNG. Choose an image and the new file is written in your browser — the picture is never uploaded and no account is needed.

What You Get

  • A lossless PNG image written from your JPEG.
  • The pixel dimensions of the result, so you can check it before downloading.
  • A clean file that opens in any editor that handles PNG.

How to Convert

  1. Drop your JPEG onto the upload area or choose it from your device.
  2. Start the conversion.
  3. Download your new PNG.

What Changes and What Stays the Same

PNG and JPEG store pixels in very different ways, and knowing the difference helps you pick the right one.

Lossless Container, Same Pixels

PNG is a lossless format: every pixel of your JPEG is copied exactly, with no further compression artefacts added. What you get is a faithful, byte-for-byte copy of the picture you started with, wrapped in a different container. Because PNG does not throw anything away, the new file is usually noticeably larger than the JPEG it came from.

What Cannot Be Recovered

Converting to PNG does not restore detail that the original JPEG already lost. JPEG compression is permanent: once a photo has been saved as JPEG, the fine detail and smooth gradients it discarded are gone, and a PNG of that file simply stores the compressed result without loss. Use this conversion when you need a PNG for an editor, a printer or a workflow that requires the format, not to improve quality.

Why the Conversion Happens in Your Browser

The image is decoded on a canvas and re-encoded by this page. Nothing is sent to a server, and the result exists only in your browser's memory until you download it. Everything runs locally, so the tool keeps working offline once it has loaded.

About Your File

The converter accepts JPEG files up to 50 MB. Transparent areas are not an issue here, since JPEG has no transparency and the picture is fully opaque, but be aware that the resulting PNG will be larger than the source.

Frequently Asked Questions

Why is the PNG bigger than the JPEG?

PNG stores every pixel without discarding data, while JPEG is designed to shrink files by removing detail the eye barely notices. A larger file is the expected result of moving from a lossy to a lossless format.

Can I go back to a smaller file?

Yes — use the "PNG to JPEG" converter to re-encode the image as JPEG, but remember that each JPEG round trip removes a little more detail.

Where is my image stored?

Nowhere. The file is processed only in your browser's memory and is never uploaded or kept anywhere.
