WebP keeps transparency like PNG but is often much smaller, which makes it ideal for website graphics and logos.

Common questions
How this tool behaves
Is the conversion lossless?
WebP is a lossy format. Use the quality slider: around 0.85 to 0.9 is visually identical for photos, and lower values make smaller files.
Can I resize at the same time?
Yes. Set a maximum width and the image is scaled down proportionally during conversion. Leave it at 0 to keep the original size.
What about transparency?
Transparency in the source is preserved in the output.
Does my browser support this format?
Yes. Every current desktop and mobile browser can read and write these formats.
Does the file leave my device?
No. The image is decoded and re-encoded by your browser. ImgNimble does not receive the source file on this page, and refreshing clears both the input and the generated result.
