Frequently Asked Questions
How do I convert PNG to WebP?
Drop your PNG files into the converter above, adjust the options if you like, and click “Convert Now”. Your WebP files are ready to download in seconds.
Why convert to WebP?
WebP files are typically 25–35% smaller than JPG at the same visual quality, which makes web pages load faster and improves Core Web Vitals scores.
Can I convert multiple images at once?
Yes. Add as many files as you like; they're processed one after another and can be downloaded together as a ZIP.
Are my images uploaded to a server?
No. Every operation runs locally in your browser using the HTML5 Canvas engine. Your files never leave your device, so they stay completely private.
Is there a file size limit?
You can process images up to 50 MB each. Very large images (above roughly 16,000 pixels on a side) may exceed what some browsers — particularly on mobile — can handle in memory.
Is this tool free to use?
Yes — it's completely free with no sign-up, no watermarks added to your output and no daily limits.
