常见问题
Quick answers.
›Will I lose image quality during conversion?
JPG uses lossy compression, so some fine detail may be lost to reduce file size. You can adjust the quality slider to find the right balance between file size and visual fidelity.
›What happens to transparent backgrounds?
The JPG format does not support transparency. Any transparent areas in your original PNG will be replaced with a solid white background by default.
›Are my images private?
Yes. This tool uses the browser's Canvas API to process images locally on your device. Your files are never sent to our infrastructure or any third-party servers.
›Can I convert multiple PNGs at once?
Yes, you can select or drag and drop multiple files to convert them in a single batch. Each image will be processed individually and made available for download.
