// ABOUT PNG
PNG uses lossless compression with full alpha-channel transparency support. It preserves every pixel exactly, making it the standard choice for screenshots, logos, web graphics, and any image where precision matters. PNG files tend to be larger than lossy alternatives but guarantee no quality degradation.
// ABOUT JPEG
JPEG uses lossy compression optimised for photographic content. It discards visual information the human eye is unlikely to notice, achieving compression ratios of 10:1 or higher with minimal perceptible quality loss. JPEG does not support transparency — any alpha channel is flattened against a white background.
// WHY CONVERT
Converting PNG to JPEG is useful when you need your image in a format suited for photographs, web images, email attachments, social media uploads, and any scenario where small file size matters more than pixel-perfect accuracy. Because JPEG uses lossy compression, some fine detail may be lost in the conversion — but for photographic content the difference is usually imperceptible. Image Toolz runs the entire conversion directly in your browser. Nothing is uploaded to any server — your files remain completely private on your device. The tool handles images up to 200 MB and most conversions complete in under a second.
// FAQ
What is PNG?
PNG (Portable Network Graphics) is a lossless raster image format that supports full transparency via an alpha channel. It is the dominant format for screenshots, web graphics, and images that require pixel-perfect accuracy.
What is JPEG?
JPEG (Joint Photographic Experts Group) is a lossy image format optimised for photographic content. It achieves high compression ratios by discarding fine detail the human eye is unlikely to notice, making it the standard for photos on the web.
Will converting PNG to JPEG lose quality?
Yes, JPEG is lossy. The degree of quality loss depends on the compression level. For photographic content the loss is usually imperceptible at quality 80–90%, but sharp edges, text, and flat-colour graphics will show visible artifacts. Transparency is not preserved — transparent pixels become white.
Is it safe to convert my files here?
Yes. All conversion runs entirely in your browser. Your images are never uploaded to any server and nothing leaves your device.
