JPG para PNG

Convert JPG and JPEG images to PNG in high quality and without losing details, 100% free and offline.

What it is

The JPG to PNG Converter is a free online tool that turns JPG files into PNG, without installing anything and without uploading your image anywhere.

Why people convert this way

PNG is lossless and opens everywhere, which is why editors, print shops and documentation tools ask for it. Converting a JPG to PNG stops any further quality loss from that point on, which matters if the file is about to be edited and saved repeatedly.

How to use it

  1. Add your file, by dragging it in or picking it from your device.
  2. Wait a moment for the conversion to finish.
  3. Download the PNG, ready to use.

You can convert several files one after another in the same session.

Your file never leaves your device

The conversion runs entirely inside your browser, using the image engine the browser already has. Nothing is uploaded to a server, nothing is stored, and nobody else ever sees the file.

That matters more than it sounds for photographs, which carry metadata: the camera model, the date, and often the exact GPS coordinates where the picture was taken. Sending a personal photo to a conversion site hands all of that to a stranger. Here there is nothing to hand over, because nothing is sent.

It also means no queue, no daily cap and no account. The only real limit is your own device.

What changes in the result

Be clear about what this does not do: it cannot recover what the JPG already threw away. Compression artefacts stay exactly where they are, they just stop getting worse. The file also gets considerably heavier, because nothing is being discarded any more.

Related: the image compressor to make a file lighter without changing format, and the image resizer to change its dimensions.

Frequently asked questions

Is my JPG file uploaded to a server?

No. The conversion happens entirely inside your browser, so the file never leaves your device. Nothing is uploaded, nothing is stored and nobody else can see it.

What changes when I convert JPG to PNG?

Be clear about what this does not do: it cannot recover what the JPG already threw away. Compression artefacts stay exactly where they are, they just stop getting worse. The file also gets considerably heavier, because nothing is being discarded any more.

Will converting to PNG improve my photo?

No, and this is the commonest misunderstanding. PNG stops any further loss from this point on, but it cannot recover what the JPG already discarded. Compression artefacts stay exactly where they are.

Why did the file get bigger?

Because nothing is being discarded any more. A JPG is small precisely because it throws detail away; a PNG keeps every pixel, so a heavier file is the expected result and the point of the conversion.
