PNG (Portable Network Graphics) is a lossless format that supports transparency, making it ideal for graphics, logos, and screenshots. JPG (JPEG) is a lossy format optimized for photographs — it achieves much smaller file sizes by discarding imperceptible visual detail. Both are universally supported, but they serve different purposes.
PNG files can be significantly larger than JPGs, especially for photographs. A 5MB PNG photo might compress down to 500KB as a JPG with no visible quality difference. If you're uploading photos to a website, sending images via email, or reducing storage usage, converting from PNG to JPG delivers substantial size savings. JPG is also the standard format expected by most print services and online platforms.
The converter draws your PNG image onto an HTML Canvas element and exports it as a JPG file at your chosen quality level. If the PNG has transparent areas, they're filled with a white background (since JPG doesn't support transparency). Everything runs in your browser — no upload, no server, no waiting.
Yes. Your images are processed entirely in your browser and never leave your device. No data is sent to any server. Convertful has zero access to your files — they exist only in your browser's memory during conversion.
JPG files are typically much smaller than PNG for photographs. Converting to JPG can reduce file size by 50-80%, ideal for web and email.
JPG uses lossy compression, so there may be a slight quality reduction. You can adjust the quality slider to balance size and quality.
JPG doesn't support transparency. Transparent areas will be filled with a white background.
