PNG is lossless and may be larger. JPEG replaces transparency with white. Target size is best effort.

Output reference

Know the result size

Will the output always be smaller?

No. A source file may already be optimized, especially PNG. The result panel shows the actual encoded size and whether it is smaller or larger.

Is a target file size guaranteed?

No. For JPEG and WebP, the browser tries lower quality down to 5%. If that still cannot reach your target, the result panel says so. Resize the image or choose another format.

What happens to transparency?

WebP and PNG retain transparency. JPEG has no alpha channel, so transparent areas become white.

Is my image uploaded?

No. Validation, encoding and download happen in your browser. The source file is not sent to a processing server.
