JPG
Convert JPG and JPEG images to PNG for lossless editing, screenshots, or tools that require PNG. The output preserves exactly what's in the JPG.
How to convert JPG to PNG
- Add your JPG or JPEG files.
- Click Convert.
- Download each PNG or get them all as a ZIP.
What converting does and doesn't do
PNG is lossless, so it preserves everything in the source — including any JPG compression artefacts that are already there. It does not recover detail the JPG lost.
You'd convert to PNG for further editing, to add transparency later in an editor, or for a platform that only accepts PNG. The trade-off is a larger file.
Everything happens in your browser using your device's own processing power. Your images are never uploaded to PrepImages, and nothing is stored after you close the tab.
Common uses
- Preparing an image for lossless round-trip editing
- Meeting a PNG-only requirement
- Getting a clean base to cut out a background
Frequently asked questions
Does converting JPG to PNG improve quality?
No. PNG is lossless, so it preserves exactly what is in the JPG — including any compression artefacts already there. It does not recover lost detail.
Why convert JPG to PNG then?
PNG is better for further editing, adding transparency, or tools and platforms that require PNG. The trade-off is a larger file.
Can I add transparency after converting?
The conversion itself keeps the solid background. You would remove the background in an image editor afterwards.
