A few useful answers
How do I convert PNG to WebP?
Choose your PNG files, adjust the quality and click Convert to WebP. Your images are processed on your device.
Will WebP files always be smaller?
No. Size depends on the original image and quality setting. Lower quality usually reduces file size but may soften fine detail. Compare the downloaded result before replacing an original.
Does PNG to WebP preserve transparency?
Yes. Transparent and partially transparent areas stay transparent. Colour detail is compressed according to your quality setting.
Is 100% quality lossless?
No. This tool uses lossy WebP encoding at every quality setting. It keeps the original pixel dimensions, but does not restore lost detail or preserve original metadata and colour profiles.
Can I batch convert images?
Yes. Convert up to 20 images, 15 MB each, 100 MB total and 150 megapixels per batch. Each image is limited to 25 megapixels. Animated PNG files are rejected.
Do my files leave my device?
No file bytes are sent to a server. Processing and downloads happen in your browser. Optional Google Analytics measures page visits and tool usage only after you accept analytics. It does not receive your files or filenames. See the privacy and limits page for details.
