Convert JPG to PNG online
Use this JPG to PNG converter when an editor, application, or upload workflow specifically requires PNG. The conversion keeps the decoded image dimensions while creating a new PNG file.
PNG uses lossless compression, so photographic PNG files are often larger than their JPG originals. Converting a JPG to PNG does not improve detail that has already been removed by JPG compression.
If your needs change, you can convert PNG to JPG or compress the image.
When should you convert JPG to PNG?
Convert JPG to PNG when a workflow specifically requires PNG or when you need to continue editing without introducing another round of JPG encoding during export.
For ordinary website photographs, JPG or WebP will often produce smaller files. If PNG is required, use realistic display dimensions so unnecessarily large files do not increase page weight.

Frequently asked questions
Can I convert JPG to PNG online for free?
Yes. Toollix lets you convert supported JPG and JPEG images to PNG online without creating an account.
Does converting JPG to PNG improve quality?
No. PNG prevents additional lossy compression in the new file, but it cannot recreate image detail already removed from the JPG source.
Will my image dimensions change?
No. The converter keeps the source image dimensions.
Why is my PNG larger than the JPG?
PNG uses lossless compression while JPG is designed to reduce photographic file sizes through lossy compression. Photographs therefore often require more storage as PNG.
Does JPG to PNG make the background transparent?
No. Converting the file format alone does not remove a background or create transparent areas.
