About formats

PNG

PNG (Portable Network Graphics) is a lossless raster image format that supports alpha-channel transparency. PNG is the standard choice for web graphics, logos, and UI elements where sharp edges and transparency matter, and it produces no loss in quality across saves.

Frequently Asked Questions

Is converting PNG to WEBP free?
Yes. This PNG → WEBP converter runs entirely in your browser and is completely free — no account, no credits, no watermark.
Which devices and platforms can I use to convert PNG to WEBP?
Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.
Are my PNG files uploaded to a server?
No. Files never leave your device. The entire PNG → WEBP conversion runs locally in your browser, so your data stays private.
Can I convert multiple PNG files at once?
Yes — batch conversion is supported. Add as many PNG files as you like and convert them to WEBP in one pass, then download the results together.
What is the maximum file size?
There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.
Will converting PNG to WEBP reduce the quality?
Because both formats use lossy compression, the WEBP output will not bring back any quality that has already been lost in your PNG file. Avoid repeated re-encoding to keep the best quality.
Will transparency be preserved when converting PNG to WEBP?
Yes. Both PNG and WEBP support alpha-channel transparency, so transparent areas of your file are kept unchanged in the WEBP output.
Will the converted WEBP file be smaller than the PNG?
Usually yes. Converting from a lossless or uncompressed format to a lossy one dramatically reduces file size. Typical savings range from 50% to 90%, depending on the quality setting you choose.
