PROCESSING TRANSPARENCY
Trust center ↗Know what happens before you upload.
A temporary per-request workspace is cleaned when processing ends.
PNG can be much larger than JPG for photographic content. Converting to PNG does not automatically improve a low-quality source or restore missing detail.
Compare file size and transparency after conversion. If the PNG becomes very large for web use, WebP may be a better fit.

INFINITY INTELLIGENCE
A copilot that understands this tool.
Ask what a setting means, whether this is the right tool, how to recover from an error, or what to do with the result next. Infinity receives safe context from this page — not the file contents automatically.
PRACTICAL CONTEXT
What this tool is good at — and where to be careful.
When this tool makes sense
Converting an image to PNG when you need crisp edges, broad support, or preservation of transparency when the source provides it.
What the engine actually does
The image is opened, EXIF orientation is normalized, and the result is saved as PNG. Conversion changes the container and encoding but cannot invent transparency or detail absent from the source.
What it does not promise
PNG can be much larger than JPG for photographic content. Converting to PNG does not automatically improve a low-quality source or restore missing detail.
A 20-second quality check
Compare file size and transparency after conversion. If the PNG becomes very large for web use, WebP may be a better fit.
Frequently asked questions
Is PNG always better?
No. It is strong for graphics and transparency but can be large for photos.
Does conversion improve quality?
It does not create new detail; it changes the image format.
