Shrink PNG Files to JPG in Seconds — Reduce Size 80%

When to convert PNG to JPG

PNG's lossless DEFLATE compression is excellent for graphics but wasteful for photographs, where JPG's lossy DCT compression removes redundancy the eye barely notices. Converting PNG to JPG typically cuts file size by 50-80%, sometimes more on photo-heavy images, by discarding fine color and luminance detail photographic content doesn't need at full precision. The tradeoff is real: JPG compresses in blocks, so every save introduces some generation loss, and results can show visible blocking or color banding around sharp edges, text, or flat-color graphics — the exact content PNG handles best. JPG also has no alpha channel, so any transparency in your PNG is flattened to a solid black background before compression, a one-way change you can't undo later. Use the quality slider to control the tradeoff: 80-90% keeps photos visually indistinguishable from the PNG source while still shrinking the file substantially. JPG is supported everywhere — every browser, phone, email client, and social platform — making it the safest choice for sharing. Avoid this conversion for screenshots, logos, or line art with transparency; the artifacts and lost alpha channel will hurt more than the smaller size helps.
