Convert Image

Choosing the right image format depends on what the image contains and where it will be used. PNG is a lossless format that preserves every pixel perfectly, making it ideal for screenshots, logos, icons, and any image with text or sharp edges. JPEG uses lossy compression that works best for photographs and complex images with smooth gradients — it produces much smaller files than PNG for photos but can introduce visible artifacts around hard edges. WebP is a modern format developed by Google that offers both lossy and lossless compression, typically producing files 25-35% smaller than equivalent JPEG or PNG files.

One important detail when converting to JPEG: the format does not support transparency. If your source image has transparent areas (common with PNG files), those areas are automatically filled with a white background during conversion. If you need to preserve transparency, convert to PNG or WebP instead. When converting from JPEG to PNG, the image will not gain any quality — it simply gets re-encoded losslessly at whatever quality the JPEG already had.

This tool processes everything locally in your browser using the Canvas API. Your images are never uploaded to any server, which means conversions are instant regardless of file size and your files remain completely private. This makes it safe to use with sensitive screenshots, personal photos, or proprietary design assets.
