Converting a JPG to PNG gives you a lossless copy of the image that won't degrade if you re-save or re-edit it. While the PNG output won't be smaller than the source JPG — and can't recover lost JPG compression artefacts — it's the right choice before further editing in tools that rely on lossless quality, or when you need transparent-layer support.

When to convert JPG to PNG

Before editing in a photo editor

Every time you re-save a JPG, it re-applies lossy compression and the image degrades slightly. Converting to PNG first lets you edit and re-save without any additional quality loss.

Adding transparency to a photo

JPG doesn't support transparent pixels. After converting to PNG you can use any image editor to erase the background and save the result with a proper alpha channel.

Lossless archiving

For images you want to preserve at maximum quality for the long term, PNG is the safer archival format — it stores pixel data exactly.

Frequently asked questions

Will converting JPG to PNG improve quality?

No — the conversion produces a lossless copy of what's already in the JPG, including any compression artefacts from previous saves. Quality can only be preserved, not improved.

Why is the PNG larger than the original JPG?

PNG uses lossless compression which stores full pixel data. For photographs this is less efficient than JPG's lossy compression, so the PNG file is usually larger.

Can I add transparency after converting?

Yes. Once you have a PNG file, any image editor (Photoshop, GIMP, Canva, etc.) can use the erase or masking tool to create a transparent background and save the result as a transparent PNG.
