Does WebP support transparency?

Yes. WebP supports transparency like PNG, making it a great choice for logos and graphics.

Will my PNG files be uploaded?

No. Mason Image converts files entirely in your browser. Nothing is sent to a server.

WebP files are typically 25–35% smaller than PNG at similar visual quality, though results vary by image.

Free · Drag & drop · Done in seconds

Image conversion that finishes in your browser — no upload required.

Why Mason Image?

Add images anywhere on the page. Select multiple files and convert them all at once.

No upload queue or waiting. Convert images in seconds, right in your browser.

WebAssembly encoders (MozJPEG, libwebp) compress your images more efficiently than basic browser tools — without sending files anywhere.

No subscriptions, no watermarks, no limits on basic conversions.

Use Mason Image on desktop, tablet, or mobile — anywhere you have a modern browser.

Mason Image processes every file locally in your browser. We never upload, store, or access your images.
