How to use the JPG to PNG Converter
Choose a JPG image up to 25 MB, wait a moment while your browser converts it, then download the PNG.
When PNG is the better format
PNG is lossless, so it is the right format when you plan to edit an image several times, add text or sharp graphics, or need a format that some design tools or upload forms require. Every save keeps exactly the same pixels, while saving a JPG again and again slowly adds compression artefacts.
What conversion cannot do
Converting to PNG does not bring back detail that JPG compression already removed, and it does not add transparency to the background. PNG files of photos are usually several times larger than the JPG, so keep the JPG for sharing photos and use PNG for editing and graphics.
Why the PNG file size is bigger
A PNG stores every pixel with lossless compression, while a JPG throws detail away to keep the file small. When you convert JPG images to PNG, the image quality stays the same as the JPG you started with, but the file size often grows by two to five times. That is expected and is the price of a format that will not lose any more detail on later saves.
Transparency
The PNG image format supports transparency, but converting does not remove a background on its own. The JPG had a solid background, so the PNG will too. To get a transparent background, open the PNG in an image editor and erase the background, then save it as PNG again.
Examples
- Worked example
Choose a JPG and download a lossless PNG at the same pixel size.
Limitations and assumptions
Conversion cannot restore detail already lost in JPG compression, and PNG files are usually larger.
Frequently asked questions
Is my image uploaded?
No. The conversion happens in your browser and the file stays on your device.
Why is the PNG bigger than the JPG?
PNG stores every pixel without lossy compression, so photos take more space. That is normal.
Will the background become transparent?
No. JPG has no transparency, so the converted PNG keeps the same solid background.
