Convert PNG to JPG to shrink screenshot file sizes for sharing, email, or upload.
PNG screenshots are huge - a single 4K screenshot can easily hit 8-10 MB because PNG stores every pixel losslessly. Converting to JPG typically cuts that to 1-2 MB with no visible quality difference for most screen content. It's the right move for emailing screenshots, posting to chat, or attaching to bug reports where the recipient just needs to see the image, not edit it.
JPG doesn't support transparency, so we flatten any transparent areas onto a white background before encoding. Sharp text and thin lines pick up a small amount of compression softening at the default quality setting (Q=92), but at typical viewing distances it's imperceptible. For pixel-perfect screenshots, keep the PNG.
PNG is a lossless image format with alpha-channel transparency. Larger than JPG for photos, but ideal for screenshots, logos, and graphics with sharp edges.
JPG (JPEG) is the dominant lossy image format on the web - small files, near-universal support, but no transparency. Best for photos and high-frequency detail.
