Why is my PNG so much bigger than the equivalent JPG?

PNG is lossless — every pixel is stored exactly. JPG throws away information the eye barely notices to shrink the file dramatically. For photos, JPG can be 5–10× smaller with no visible loss.

What happens to transparency when I convert PNG to JPG?

JPG has no alpha channel. Transparent pixels in the source PNG are composited onto a white background during conversion. If you need transparency, convert to WebP instead.

Is converting PNG to JPG good for screenshots?

Photographic screenshots — yes, you'll save a lot of space. Screenshots full of UI text and sharp edges — not really; JPG creates ringing artifacts around text. Try lossy WebP for a better trade-off on UI captures.

Will quality 85 be enough for printing PNG content as JPG?

For typical web prints (4×6 photos, social media), yes. For fine-art prints or A3+ sizes, push to quality 95 to keep the largest possible signal margin.

Do you reduce the resolution when converting PNG to JPG?

No. The output JPG has the same pixel dimensions as the source PNG. The resize toggle in Output settings is opt-in if you want to downscale.

Is browser PNG to JPG conversion as good as Photoshop's?

For default JPG export at the same quality, the visual output is essentially identical. Modern browser canvas encoders use mozjpeg-equivalent tuning under the hood.

About PNG to JPG conversion

PNG (Portable Network Graphics) was introduced by W3C and Microsoft in 1996 as a free, patent-unencumbered replacement for GIF. Its core feature is lossless compression — what goes in comes out pixel-perfect — plus a real alpha channel for transparency. That makes PNG ideal for screenshots, UI assets, logos, and any image with sharp edges or text. The downside is file size: photographic PNGs are typically 4–10× larger than the equivalent JPG. JPG (formally JPEG) was finalized by the ISO Joint Photographic Experts Group in 1992 and is still the dominant photographic format on the web. Its discrete cosine transform compression discards information the human eye is unlikely to notice — color subtleties, fine high-frequency detail — to achieve dramatic file size reductions. JPG has no transparency support, so any alpha channel in the source PNG is composited onto white during conversion. Converting PNG to JPG is the right call when the source is photographic, file size matters, and you don't need transparency. It's the wrong call for icons, line art, or anything with crisp edges, where JPG ringing artifacts will start to show up.
