Will I lose transparency when converting to JPG?

Yes. JPG does not support transparency. Transparent areas will be filled with a solid background color (usually white). If you need transparency, keep the file as PNG or convert to WebP.

How much smaller will the JPG be?

It depends on the image content. Photographs typically shrink 50-90% compared to the PNG version. Simple graphics with large flat areas may see less dramatic reductions.

Can I convert JPG back to PNG?

You can change the container format back to PNG, but the quality lost during JPG compression cannot be recovered. Always keep your original PNG if you may need it later.

When to Convert PNG to JPG

PNG is the right choice for images with transparency, text overlays, or flat graphics like logos and icons. But when you have a photograph or a complex illustration with millions of colors, JPG is almost always a better fit. JPG uses lossy compression tuned for continuous-tone images, meaning it discards details the human eye struggles to see. The result is a file that can be a fraction of the PNG size while looking virtually identical on screen.

PNG vs JPG at a Glance

PNG: lossless, supports transparency, larger files, ideal for graphics and screenshots.
JPG: lossy, no transparency, much smaller files, ideal for photos and gradients.
WebP: a modern alternative that supports both lossy and lossless compression with transparency — consider it if browser support is acceptable for your audience.

Quality Settings Explained

JPG quality is typically expressed on a 1-100 scale. At 100 the file is nearly lossless but large. At 60 artifacts become visible in gradients and sharp edges. The sweet spot for most photos is 80-90, which produces small files with no perceptible quality loss. For web thumbnails and previews, even 70 can be acceptable.
