Convert Image Format Online Free

Image format conversion sounds technical but it's actually about choosing the right tool for the job. JPG is great for photos but terrible for graphics with text. PNG preserves quality and supports transparency but creates huge file sizes for photos. GIF is only useful for simple graphics and animations. BMP is uncompressed and enormous. Each format has ideal use cases, and converting between them lets you optimize images for specific purposes. The most common conversions are PNG to JPG (for photos that don't need transparency - reduces file size dramatically) and JPG to PNG (for graphics or screenshots that need sharp text and edges). Less common but useful: converting old BMP files to modern formats, or creating GIFs from photos for simple web use. Our converter handles all these scenarios. It also handles batch conversion - upload 50 PNGs, convert them all to JPG at once, download as a ZIP. One thing that confuses people: converting to PNG doesn't magically improve quality. If you start with a low-quality JPG and convert to PNG, you get a low-quality PNG. Larger file size doesn't mean better quality - just different compression. The converter preserves whatever quality exists in the source image. For JPG output, you control the quality level. Higher quality means larger files but better preservation of detail. For web images, 70-80% quality is usually fine. For print work or high-quality needs, use 90%+.
