How-to
This page helps you convert PNG to WEBP for general web use. WEBP often reduces file size while keeping good quality, which can improve load speed and user experience.
When to use PNG vs WEBP: PNG is great for editing and lossless storage, but for delivery on the web, WEBP is usually more efficient. If your PNG has transparency, WEBP can keep it in modern browsers.
Recommended settings: start with Quality ~0.80 for a good balance. If you need maximum visual fidelity (logos or UI), try 0.85–0.90. If your goal is speed, try 0.70–0.75.
Resizing tip: many images are larger than needed. If your site displays images at 1200px width, exporting at 2400px is wasteful. Resize (max width) before exporting if you don’t need full resolution.
For general web use, the main goal is usually: Convert In Browser. After converting, test your page: make sure transparency looks correct and text/edges remain sharp.
Privacy note: this converter runs locally in your browser. Your image is not uploaded to a server. That’s useful when working with client assets or private files.
Common workflow: convert one representative image first, check quality, then apply the same settings to similar images. Consistency matters more than chasing the absolute smallest size for every single file.
If your WEBP looks blurry: increase quality slightly or avoid resizing too aggressively. Small icons and sharp edges can require higher quality than photos.
If your page speed doesn’t improve: check whether your site is actually serving WEBP to visitors and whether caching/CDN is configured correctly. Format conversion is one part of performance.
Naming tip: keep filenames stable when replacing images (if your CMS supports it) or update references cleanly. Broken image links can happen if filenames change without updating the site.
Transparency tip: if you see a halo, your original PNG may have semi-transparent edges designed for a specific background. Test the WEBP on the real background color you use.
Common mistakes
- Converting at very low quality for logos/icons (causes artifacts).
- Resizing too small and then upscaling on the site (looks blurry).
- Forgetting to update image references after replacing files.
- Not testing transparency on the real background color.
