Frequently Asked Questions
- Will the PNG be lossless?
- Yes. PNG is lossless. However, if the source JPG had compression artifacts, those will be preserved.
- Can I add transparency to the output PNG?
- The converter does not add transparency — that would require removing a specific background color. The output is a full-color PNG.
- Will the PNG be larger than the JPG?
- Yes. PNG files are typically larger than JPG because they're lossless. This is expected.
- Is metadata preserved?
- EXIF metadata is preserved where possible during conversion.
- Can I batch convert JPGs?
- Yes, batch conversion is available on Pro and Business plans.
