About image format conversion
Different image formats have different trade-offs between file size, quality, compression and browser support. Pixuno's converter lets you switch between formats instantly using your browser's built-in Canvas API — no server, no account, no waiting.
JPEG is the standard for photographs. Lossy compression reduces file size at some quality cost. Best for photos and complex images.
PNG is lossless and supports transparency. Best for graphics, logos and screenshots where sharpness matters.
WebP combines the strengths of both: smaller files than JPEG with transparency like PNG. Ideal for the modern web.
AVIF is the next-generation format with exceptional compression and broad color support.
FAQ
Which formats can I convert between?
Pixuno supports JPEG, PNG, WebP, AVIF and BMP as output formats. You can open JPEG, PNG, WebP, AVIF, GIF, BMP and TIFF files. Note: converting a GIF removes animation (only the first frame is converted).
What quality setting should I use?
For web images, quality 80–85 typically produces excellent results with a much smaller file size than 100. For print or archiving, use 90–95. PNG is lossless so quality setting does not apply.
What is WebP and why should I use it?
WebP is a modern format developed by Google. It provides 25–35% smaller file sizes than JPEG at equivalent quality, with full transparency support. It is supported by all modern browsers.
What about AVIF?
AVIF is the newest format and can compress even better than WebP. However, browser support is still spreading — it works in Chrome 85+, Firefox 93+ and Safari 16+. If compatibility is important, use WebP instead.
