Frequently Asked Questions

Why is the converted PNG file larger than my original JPG?

JPG uses lossy frequency compression, whereas PNG is a lossless raster format. Converting to PNG prevents any future generation loss when editing, which requires more bytes.

Does converting JPG to PNG automatically remove the background?

No. Converting formats changes the container encoding to support an alpha channel, but existing solid background pixels remain opaque.
