How to use this PNG to WEBP Converter?

1. Choose one or more files or drop them into the input area.
2. Adjust the available settings, then click Convert. Processing stays in this browser; nothing is uploaded.
3. Download each result or download a ZIP for multiple files. Results disappear when you leave this page.

PNG to WebP: choose the right output

PNG keeps every pixel and supports transparency. WebP can keep transparency while offering either lossy compression for smaller downloads or lossless compression for graphics that need precise edges. Keep the original PNG if you may edit it later.

• Choose Lossy for photographs or web graphics when file size matters. The quality slider controls the size and detail tradeoff.
• Choose Lossless WebP for logos, icons, screenshots, and artwork with sharp edges. The quality slider does not apply in this mode.
• Leave width and height blank to keep the original dimensions. Resizing changes the pixels even when the WebP encoding is lossless.

PNG to WebP example

The same 512 × 512 transparent artwork is shown below. These are real outputs at the stated settings; your savings will depend on your image.

What happens to transparency and files?

Transparent areas stay transparent in both WebP modes. Conversion and ZIP creation happen in this browser; your selected files are not uploaded. You can download individual results or one ZIP when you convert multiple images. Each input is limited to 20 MB.
