About

PNG to JPG Transparent areas become white — great for screenshots and illustrations. Everything runs locally in your browser — your images never leave your device, protecting privacy and skipping upload waits. Drop many images at once to batch-process, then download all as a ZIP. The interface switches between 中文 and English.

FAQ

Are my images uploaded?+

Batch supported?+
Yes. Drop many images or a whole folder to process at once; results download as a ZIP.
What about transparency?+
Transparent pixels are filled white, since JPG has no alpha.
