Supports JPG, PNG, WebP, GIF, SVG • Up to 50 images • No size limit
Use JPG for photographs, PNG for graphics/screenshots with transparency, WebP for everything on modern websites.
Converting PNG to JPG can reduce file size by 80%+ but you’ll lose transparency.
WebP is supported by 97%+ of browsers and is the recommended format for web use in 2026.
PNG is lossless — converting JPG to PNG won’t improve quality, it will just increase file size.
Choosing the right image format is crucial for balancing file size, quality, and feature support. Each format has strengths that make it ideal for specific use cases.
JPEG has been the standard format for photographs since the 1990s. It uses lossy compression, meaning it permanently removes some image data to reduce file size. At quality levels above 80%, the visual loss is virtually undetectable. JPEG is universally supported and produces the smallest file sizes for photographic content. Its main limitation is the lack of transparency support.
PNG uses lossless compression, preserving every pixel exactly. This makes it perfect for screenshots, logos, icons, diagrams, and any image with text or sharp edges. PNG supports full transparency (alpha channel), allowing images to be placed on any background. The trade-off is larger file sizes compared to JPEG for photographic content.
Developed by Google, WebP combines the benefits of both JPEG and PNG. It supports both lossy and lossless compression, transparency, and animation. WebP files are typically 25-35% smaller than JPEG at equivalent quality, making it the recommended format for web use. As of 2026, WebP is supported by all major browsers including Chrome, Firefox, Safari, and Edge.
Converting from a lossy format (JPEG) to a lossless format (PNG) will not improve quality — the quality was already lost during the original JPEG compression. The file will actually be larger in PNG format with no visual benefit. Converting from PNG to JPEG will reduce file size significantly but will permanently remove transparency and may introduce compression artifacts on sharp edges and text.
