FAQ
What happens to a transparent PNG background?
JPG has no alpha channel, so transparent areas are filled with white. If the artwork was designed for a non-white background — an icon meant for a dark page, say — you will see obvious white blocks. Convert to WebP instead in that case.
How much smaller will the JPG be?
It depends on the content. Photographic PNGs typically shrink by 70% or more, because JPG handles continuous tone far more efficiently. Flat icons, screenshots, and line art were already well suited to PNG, so the saving is smaller — and JPG can introduce noise around sharp edges.
Does converting lose quality?
Yes. JPG is lossy, so the image is re-encoded. Above quality 90 the difference is usually invisible; below 60, noise appears around sharp edges and text. Your original file is never modified.
When to convert PNG to JPG
The usual reason is size. Design apps, screenshot tools, and phones often export PNG, and a photographic PNG can easily run to several megabytes. When you need to meet a form's size limit, send a file by email, or speed up a web page, converting to JPG often cuts the size by 70% or more with almost no visible change for photos.
Watch the content type, though. If the PNG is an icon, a flat screenshot, or line art, JPG is a poor fit — it struggles with sharp edges, adds noise around text, and may not save much. Keep those as PNG, or convert them to WebP instead.
Transparency becomes white
This is the one thing to watch when converting PNG to JPG. JPG has no alpha channel, so anything transparent is filled with solid white. An icon meant to sit on a dark background will come out with an ugly white box around it. When that matters, convert PNG to WebP instead: it shrinks the file just as well while keeping transparency intact. Only when the image is already opaque — a photo or a white-background graphic — is JPG a safe choice.
