Convert PNG to WebP Online Free & Fast
Turn your PNG images into smaller WebP files in seconds. No installs, no software just upload, convert and download.
This tool converts PNG images to WebP, a modern format built for the web. Unlike converting to JPG, converting to WebP keeps any transparency your PNG has WebP supports the same alpha-channel transparency as PNG, just with more efficient compression. WebP can be encoded either losslessly, matching PNG's exact quality at a smaller file size, or with lossy compression for even smaller files at a quality trade-off similar to JPG. Upload your file and download a WebP in seconds; it's deleted automatically within an hour.

Frequently Asked Questions
Will converting PNG to WebP keep my transparency?
Yes. Unlike JPG, WebP supports the same alpha-channel transparency PNG does, so transparent areas stay transparent after conversion.
Will converting to WebP reduce my image quality?
It depends on the encoding used. WebP can be lossless, matching PNG's exact quality at a smaller file size, or lossy, trading some quality for even smaller files. Either way, WebP is generally more efficient than PNG at a comparable quality level.
How much smaller will the WebP file be than my PNG?
It varies by image, but WebP typically produces noticeably smaller files than PNG, especially for graphics with flat colors, gradients or transparency.
Does WebP work in all browsers?
Yes. All major modern browsers Chrome, Firefox, Safari and Edge support WebP.
Why would I keep the PNG instead of converting?
Mainly for compatibility with older software or platforms that don't yet support WebP, or if you specifically need a format that's universally recognized for editing and archiving.
Is there a limit on how many PNGs I can convert?
The free plan allows 10 conversions a day for files up to 10 MB. Paid plans remove the daily limit and raise the file-size cap.
Is it safe to upload my PNG files?
Yes. Conversion is automated, uploads are encrypted (HTTPS/TLS) and every file is permanently deleted within 60 minutes. Your images are never used to train AI models.
