Converting a photo to PNG will not make it smaller

There is a persistent belief that PNG is the higher-quality format and therefore the better choice. For a photograph it is the more expensive one. PNG stores every pixel losslessly, so converting a JPG simply preserves what the JPG already decoded to — no detail comes back, and the file grew six times here. The reasons to reach for PNG are real but specific: you need transparency, you are editing and re-saving repeatedly and want to stop the losses accumulating, or you are working with screenshots and flat graphics where lossless compression is genuinely efficient.

What this tool does

Convert JPG to PNG turns JPG (JPEG) photos into PNG files in your browser. PNG is lossless and supports transparency, so this is what you want when you need a clean copy without further compression artifacts, or a base you will later cut a background out of.

How it works

Upload a JPG, and the tool decodes it and re-encodes it as a PNG on your device. Preview the result and download the new file. Nothing is uploaded.

When to use Convert JPG to PNG

FAQ

Will this add transparency?

A JPG has no transparency to recover, but the resulting PNG can hold transparency once you edit it.

Does PNG lose quality?

No. PNG is lossless, so it will not add new compression artifacts.

Are my files uploaded anywhere?

No. The conversion runs in your browser and the image never leaves your device.
