Convert PNG to JPG Online Free

PNG (Portable Network Graphics) uses lossless compression: every pixel is stored exactly as it was in the original. This guarantees perfect quality but produces large files — especially for photographs. A 12-megapixel photo saved as PNG is typically 15-30MB.

JPG (Joint Photographic Experts Group) uses lossy compression that discards visual data the human eye is least likely to notice. At 80-90% quality, a 12-megapixel photo is typically 2-5MB — 80-90% smaller than the PNG equivalent — with differences that are invisible at normal viewing distances.

For screenshots, logos, and graphics with sharp edges and solid colors, PNG compresses better and looks better. For photographs and real-world scenes, JPG is vastly more efficient.

Convert PNG to JPG when: you have a photograph saved as PNG (common when downloading images from some websites), the PNG file is too large to email or upload to a form, you want to reduce storage space for a large library of images, or you are preparing images for a website where file size directly affects page speed.

Keep PNG when: the image has transparent areas (JPG replaces transparency with white), the image contains text or sharp graphics that look worse with JPG compression, or you are archiving an original and want to preserve every pixel.

JPG does not support an alpha channel, which is how PNG stores transparency information. When you convert a transparent PNG to JPG, every transparent or semi-transparent pixel must be assigned a solid color. Our tool replaces transparent areas with white, which works for most use cases (documents, forms, white-background images).

If your PNG has transparency and you need to keep it, use WebP instead of JPG. WebP supports full transparency at significantly smaller file sizes than PNG. Use our PNG to WebP converter to get the best of both worlds.
