Full capability guide
Predictable format conversion
Conversion pages enforce their advertised formats and explain every change made to the output.
Format-aware controls
Quality appears only for lossy JPEG and WebP output; PNG uses lossless encoding.
Transparency and sizing
Choose the JPEG background color, limit maximum width and prevent smaller images from being enlarged.
Naming and duplicates
Build names with {name}, {format} and {index}; duplicate outputs can be numbered or reported as individual errors.
Per-file evidence
Review format, dimensions, metadata policy and visual comparison, then retry or reprocess one file with current controls.

How to convert JPG to PNG
- Add one or more JPG images.
- PNG is already selected as the output.
- Convert and download the new file or ZIP batch.
What changes after conversion?
PNG stores the decoded pixels without additional lossy compression. It does not recreate detail removed when the original JPG was made, so the PNG may be larger without looking sharper.
JPG to PNG FAQ
Will the PNG have better quality?
It prevents another JPEG quality loss during this conversion, but it cannot restore missing source detail.
Does a JPG become transparent?
No. Conversion does not invent transparency that was not present in the source.
Why is the PNG larger?
PNG uses lossless compression, which is often less compact for photographs.
