Frequently Asked Questions
What happens to transparency when converting a PNG to JPG?
Because the JPEG specification does not support transparency, transparent areas are automatically filled with solid white (#FFFFFF) before export, preventing dark or distorted background artifacts.
Can I convert images to GIF or BMP with this tool?
No. This converter focuses specifically on the three dominant web standards: JPG, PNG, and WebP.
Is there any loss of image quality during conversion?
Converting to PNG is completely lossless. Converting to JPG or WebP applies an optimized 92% quality setting, which preserves sharp edges and colors while producing web-efficient file sizes.
Are my images uploaded to an external server?
No. The entire conversion process runs locally in your web browser using HTML5 Canvas. Your images never leave your computer or phone.
