JPG to PNG Converter

Convert JPG images to PNG online for free. Batch conversion in your browser, no upload limits and no credits used.

Converting JPG to PNG does not improve the image. PNG is lossless, so it will store what the JPEG currently looks like perfectly — including every compression artifact the JPEG already has — in a considerably larger file. There are good reasons to do it, but "to get better quality" is not one of them.

Lossless does not mean restored

A lossless format promises that what goes in comes out unchanged. It cannot promise anything about what went in. The detail a JPEG encoder discarded is not recorded anywhere in the file, so no conversion can bring it back. What you get is a perfect copy of an imperfect image.

The real reasons to convert

The good reasons are all about what happens next, not about the current image. PNG gives you a working copy you can edit and re-save repeatedly without the generational loss that degrades a JPEG a little more every time it is saved.

  • You are about to edit repeatedly and want no further loss with each save.
  • You need to add transparency — PNG can hold an alpha channel the JPEG never could.
  • A tool, printer, or upload form only accepts PNG.

Expect the file to grow

A photograph as PNG is routinely five to ten times the size of the same photograph as JPEG, and the artifacts inherited from the JPEG make it worse — compression noise is high-frequency detail, which is precisely what lossless formats spend the most bytes recording. If size matters and you are not editing, keep the JPEG.

Frequently asked questions

Does converting JPG to PNG improve image quality?
No. PNG stores the image losslessly from this point forward, but the detail the JPEG discarded is not in the file and cannot be recovered. You get an exact copy of the current image, artifacts included.
Does converting to PNG add transparency?
No. It makes transparency possible — PNG has an alpha channel — but the converted image is fully opaque until you actually remove or erase something.
Why is the PNG so much bigger than the JPG?
PNG records every pixel exactly, and the compression noise inherited from the JPEG is fine high-frequency detail that is expensive to store losslessly. Five to ten times larger is normal.
When is converting JPG to PNG actually worth it?
When you are about to edit and re-save repeatedly, when you need to add transparency, or when something downstream only accepts PNG. For simple viewing or sharing, keep the JPEG.
