Transparency is flattened
JPEG cannot store transparent pixels. Transparent areas use the background colour in your settings, which is white by default.

Convert PNG to JPEG
Use this when a PNG is a photograph or an image that does not need transparency. JPEG uses lossy compression, so compare the downloaded copy with your original before using it.

When should a PNG become a JPEG?
PNG is lossless and supports transparency, which suits logos, line art, and interface graphics. JPEG can be a more practical format for photographs, but converting is lossy and does not guarantee a smaller file for every image.
Frequently asked questions
Will the JPEG look different?
It can. JPEG is a lossy format, and the visible difference depends on the source image and quality setting. Keep the PNG until you have checked the downloaded JPEG.
What happens to transparent areas?
JPEG has no alpha channel. Transparent areas are filled with the background colour in your settings, which is white by default.
Are my PNG files uploaded?
No. The conversion runs in this browser on your device. MorphoThat does not receive the image for processing.
Quality 90 by default
The tool starts at quality 90. Appearance and file-size changes vary with the source image, so inspect the result rather than relying on a fixed saving.
