PNG and JPG are the two most common image formats, but they serve different purposes. JPG uses lossy compression — great for photos and gradients, but it discards some detail permanently. PNG is lossless — every pixel is stored exactly, making it ideal for graphics, logos, screenshots, and images that need a transparent background.
When to convert JPG to PNG: Convert to PNG when you need to edit the image further without degrading quality, when you need a transparent background, or when you are working with graphics that have sharp edges and text that JPEG compression would blur.
How it works:The tool draws your JPG onto an HTML Canvas element and exports it as a PNG using the browser's native encoder. The conversion is exact — no colour shifts, no blurring.
File size note: PNG files are larger than JPG files for photographic content. If you need a small file size, consider compressing the PNG afterward or converting to WebP instead.
