PNG to JPEG — Settings and quality

Worked example

PNG to JPEG has no settings to tune: the output is JPG at a fixed 92 percent quality, so your real choice is which file goes in.

That fixed 92 percent suits catalogue photos and print proofs but is generous for the web. A 1200 × 1200 px product photo saved as a 2 MB PNG usually lands in the low hundreds of KB, while a flat 40 KB logo can come out larger as JPEG than it was as PNG. The page shows a rough estimated output size before you press convert, so use it as a sanity check, not a promise.

If you need a smaller file, do not convert twice. Re-compressing a JPEG stacks a second round of loss on the first. Go back to the PNG master and use the Compress tool with JPG selected instead, where the quality slider runs from 20 to 95 and starts at 78. Around 80 to 85 is a comfortable range for marketplace listings.

The common mistake is shrinking a screenshot or logo this way and then wondering why the text looks smudged. Text and hard edges are the first things JPEG damages, so for those keep PNG, or accept the higher quality and larger size.

To decide quickly, convert two representative files, one photo and one graphic, and compare their sizes and edges at 100 percent before running the whole batch of up to 12.

PNG + alpha

JPEG + opaque background

Quality cannot be adjusted here; use the Compress tool on the original PNG if you need a smaller JPEG than the fixed 92 percent gives.
