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.
