Image Format Conversion Explained
Different image formats serve different purposes. JPEG is best for photographs with millions of colors. PNG supports transparency and lossless compression, ideal for logos and graphics. WebP is Google's modern format offering superior compression with both lossy and lossless modes.
Converting between formats lets you optimize images for specific use cases. A PNG screenshot can become a much smaller WebP file for your website. A JPEG photo can be converted to PNG when you need to overlay it on different backgrounds.
ToolPix converts images using the browser's built-in Canvas API, which means your files are processed locally with zero server uploads. The conversion is instant and handles files of any size.

Frequently Asked Questions
What is the difference between JPEG, PNG, and WebP?
JPEG uses lossy compression, best for photos. PNG uses lossless compression and supports transparency, ideal for graphics. WebP supports both lossy and lossless modes with 25-35% better compression than JPEG.
Which format is best for websites?
WebP is the best choice for web images — it offers the smallest file sizes with good quality. All modern browsers support WebP. Use PNG only when you need transparency that WebP doesn't suit.
Does converting between formats reduce quality?
Converting to a lossy format (JPEG, lossy WebP) reduces quality slightly. Converting to PNG is lossless. Avoid converting between lossy formats multiple times, as quality degrades with each conversion.
Can I convert images with transparent backgrounds?
Yes. When converting to PNG or WebP, transparency is preserved. Converting to JPEG replaces transparency with a white background since JPEG doesn't support transparency.
Are my files uploaded to any server?
No. The conversion happens entirely in your browser using the Canvas API. Your images never leave your device.
