Frequently Asked Questions
What is the difference between PNG and WebP?
PNG is a lossless format with wide support and transparency. WebP is a newer format that supports both lossless and lossy compression, and can often produce smaller files at similar quality, which is useful for the web.
Will converting PNG to WebP reduce image quality?
With lossless mode enabled, no quality is lost. With a lower quality setting, WebP uses lossy compression to reduce file size, which can slightly affect fine detail.
Does WebP support transparency?
Yes. WebP supports alpha transparency, and transparent areas in your PNG images are preserved in the converted WebP files.
Are my PNG images uploaded or stored?
Your images are uploaded to our server only to perform the conversion. The temporary files are automatically deleted after processing and are not kept.
Can I convert multiple PNG files at once?
Yes. You can upload and convert up to 20 PNG images at a time and download them together as a ZIP file.
Why is the WebP file sometimes not smaller?
Small or already-optimized PNG images, or lossless conversion of complex graphics, can occasionally produce a WebP file of a similar or larger size.
Which browsers support WebP?
WebP is supported by all current major browsers, including Chrome, Firefox, Edge, Safari, and Opera.
