WebP is a modern image format built by Google specifically to be smaller than JPG and PNG without a visible quality trade-off. It's been around for over a decade, and most major browsers now display it fine — but "most" isn't "all," which is why conversion tools still matter.

What Is WebP, and Why Does It Exist?

JPG and PNG were designed decades ago under very different constraints than today's web. WebP was built to replace both: it supports lossy compression like JPG (for photos) and lossless compression with transparency like PNG (for graphics and logos), usually producing smaller files than either at equivalent quality. That's why so many websites now serve WebP images by default — smaller files mean faster page loads.

When to Convert to WebP

  • Publishing to a website or blog where smaller file sizes directly improve load time and search ranking.
  • Sending images where storage or bandwidth matters — smaller files upload and download faster.
  • Replacing a PNG that doesn't actually need pixel-perfect lossless quality — WebP's lossy mode can shrink it substantially while keeping transparency.

When to Convert Away From WebP

The reverse conversion — WebP to JPG or PNG — comes up just as often, usually because:

  • An upload form or app only accepts JPG/PNG and rejects WebP outright.
  • You're sending the image to someone using older software that can't open WebP files.
  • A print or design tool expects a more universally supported format.

How to Convert

  1. Pick the direction you need: JPG to WebP, PNG to WebP, WebP to JPG, or WebP to PNG.
  2. Upload your image — nothing leaves your browser.
  3. For WebP output, adjust the quality slider if you want a smaller file at the cost of some quality.
  4. Download the converted file.
Tip: Converting a PNG with transparency to WebP keeps the transparent areas intact — WebP supports an alpha channel the same way PNG does.

Browser Compatibility Notes

Nearly every current browser can display WebP images without issue. Creating them is a different story — not every browser's image-encoding engine supports generating WebP output, particularly some older versions of Firefox and Safari. Fixoona's WebP converters check for this automatically when the page loads and will show a clear message if your specific browser can't produce a WebP file, rather than silently failing.

FAQ

Is WebP always better than JPG or PNG? For file size, usually yes — WebP typically produces smaller files at comparable visual quality. But compatibility is the trade-off: a handful of older browsers, some desktop image viewers, and certain upload forms still don't accept it.

Why can't I export WebP in some browsers? WebP encoding support varies by browser. Chrome and Edge support it reliably; some versions of Firefox and Safari have more limited support for creating (not just viewing) WebP files. Fixoona's converters detect this automatically and will tell you if your browser can't export WebP.

Does converting to WebP lose quality? WebP supports both lossy and lossless compression. Converting from a JPG (already lossy) to WebP at high quality settings preserves visual quality well, though re-compressing any image more than once causes some cumulative quality loss — this is true of any format.

Does WebP support transparency like PNG? Yes — WebP supports an alpha channel just like PNG, so converting a transparent PNG to WebP keeps the transparent areas intact.
