JPG to PNG: What the Conversion Does — and Does Not Do
Converting JPG to PNG creates a lossless PNG representation of the pixels that are currently in the JPG. It does not restore details that were already removed by earlier JPEG compression.
The result is useful when a workflow specifically requires PNG, but the new file can be larger because PNG stores the decoded image losslessly.
How JPG to PNG works
- Select one or more JPG images.
- The browser decodes each JPG and writes the visible pixels into a PNG.
- Download the PNG result.
FAQ
Frequently asked questions
Does JPG to PNG improve quality?+
No. The PNG can prevent additional lossy encoding, but it cannot restore information that the JPG already lost.
Why did my file become larger?+
PNG stores image data losslessly. Photographic content that was compact as JPEG can require substantially more space as PNG.
Will the new PNG have transparency?+
A normal JPG has no transparency information, so conversion alone cannot invent transparent areas.
Are dimensions preserved?+
Yes. The conversion changes the file format, not the width and height.
When should I keep the JPG instead?+
For ordinary photographs where small file size matters, keeping JPG or converting to WebP may be more practical than PNG.
