Better Quality
Lossless compression preserves all image data. No quality degradation over multiple saves. Crisp edges and sharp text—ideal for screenshots and graphics.
Web Design
PNG is standard for web graphics, UI elements, and digital design. Better for images with text, sharp lines, or detailed graphics requiring precision.
Print Quality

Understanding JPG and PNG Formats
What is JPG/JPEG?
JPEG (Joint Photographic Experts Group) is lossy compression format—reduces file size by discarding some image data. Compression ratio ~10:1. Best for photographs, realistic images, web photos. File extensions: .jpg, .jpeg (same format). Supports 16.7 million colors. Does not support transparency—always solid background. Multiple saves degrade quality progressively.
JPG Advantages: Small file sizes for fast web loading, universal browser support, good for photos with gradients. JPG Disadvantages: Lossy compression reduces quality, no transparency support, artifacts appear with text or sharp edges, quality degrades with re-saving.
What is PNG?
PNG (Portable Network Graphics) uses lossless compression—preserves all image data, no quality loss. Two variants: PNG-8 (256 colors) and PNG-24 (16.7 million colors + alpha transparency). Supports full transparency with alpha channel—essential for logos, icons, overlays. File sizes larger than JPG but quality superior. No quality degradation over multiple saves.
PNG Advantages: Lossless quality, transparency support, crisp text and sharp edges, no artifacts, unlimited re-saves without quality loss. PNG Disadvantages: Larger file sizes than JPG, not ideal for photographs (file size too big), slower web loading for large images.
Common Use Cases
🎨 Graphic Design
Convert JPG logos to PNG for transparency. Create design elements that overlay seamlessly. PNG essential for Photoshop, Illustrator, design software. Maintain quality through editing iterations without compression artifacts degrading work.
🌐 Web Development
PNG for website logos, icons, UI elements requiring transparency. Buttons, badges, watermarks need transparent backgrounds. Better quality for text-heavy images. Screenshots, diagrams, infographics benefit from PNG's lossless compression maintaining clarity.
📱 App Development
Mobile apps require PNG icons and graphics with transparency. App store screenshots need PNG format. UI elements, splash screens, notification icons all use PNG. Better quality on high-resolution mobile displays without artifacts.
🖨️ Print Materials
PNG maintains quality for printing business cards, brochures, flyers. No compression artifacts in printed materials. Better color accuracy for professional printing. Logos, graphics, diagrams print cleaner and sharper in PNG format versus JPG.
