How to convert PNG to JPG
Choose a valid PNG file, select the JPEG quality and background behavior offered by the workspace, convert it locally, inspect the result, and download the JPG. The selected PNG is not uploaded for conversion.
Choose JPG for the right kind of image
JPEG is a lossy format with broad compatibility and is often a good fit for photographs, screenshots with photographic content, and images that do not need transparency. PNG remains preferable for some lossless graphics, pixel art, or assets where exact sharp edges and transparent pixels matter.
If your main goal is smaller bytes rather than specifically JPEG output, compare PNG to WebP and Image Compressor as well. The best result depends on the image and the destination rather than the filename alone. See the image size, format, and quality guide for a decision sequence.
Transparency becomes a background
JPEG cannot store an alpha channel. Any transparent or semi-transparent PNG pixels must therefore be composited onto a background before export. Check the workspace background setting and inspect logos, icons, shadows, and antialiased edges carefully: a background that looks fine on white may show an unwanted halo on another design.
Keep PNG or use a transparent-capable output when the destination needs transparent pixels.
Quality is a trade-off, not a percentage guarantee
A JPEG quality setting controls encoder behavior. It does not mean that a 75% setting preserves exactly 75% of the original detail or produces a predictable file-size reduction. Fine text, sharp UI screenshots, noisy photographs, and smooth portraits respond differently.
Start with a moderate-high value, compare the rendered result at normal viewing size, and reduce quality only while artifacts remain acceptable. If the source is much larger in dimensions than needed, resize the image before pushing quality very low.
Troubleshooting a larger-than-expected JPG
A converted JPG can be larger than the PNG when the PNG is already highly optimized or contains simple graphics that PNG compresses efficiently. Compare the actual byte sizes instead of assuming JPEG must be smaller. A conversion can still be useful for compatibility even when it is not a size optimization.
Privacy and limits
Conversion runs in the current browser tab and does not send the PNG to a processing server. The page still uses normal website requests for its own HTML and assets; this privacy guide explains the distinction.
The workspace enforces file, format, and image-size boundaries to avoid silently processing unsupported inputs. Keep important originals before replacing production assets.
