- You do not need transparency
- Sharing via email or messaging apps
Convert to PNG When:

Frequently Asked Questions
Will I lose quality when converting formats?
It depends on the conversion. PNG to JPEG may lose some quality because JPEG uses lossy compression. PNG to PNG or WebP conversions preserve quality. Our default 90% quality setting minimizes visible differences. For lossless conversion, choose PNG as the output format.
What happens to transparency when converting to JPEG?
JPEG doesn't support transparency, so transparent areas will be filled with a solid color (usually white or black). If you need to preserve transparency, choose PNG or WebP as your output format.
Is WebP supported everywhere?
WebP is supported in all modern browsers (Chrome, Firefox, Safari, Edge) and has been for several years. However, some older systems, email clients, or image editing software may not support it. For maximum compatibility, JPEG and PNG are safer choices.
Can I convert animated GIFs?
This tool converts the first frame of an animated GIF to a static image. Animation is not preserved. For animated image conversion, you would need a specialized tool that handles animation frames.
Which format produces the smallest file size?
For photographs, JPEG and WebP produce the smallest files. WebP typically beats JPEG by 25-35% at equivalent quality. For graphics with solid colors and sharp edges, PNG can sometimes be smaller than JPEG. Test different formats to see which works best for your specific image.
Is my image uploaded anywhere?
No. All conversion happens in your browser using the HTML5 Canvas API. Your image never leaves your device and no data is sent to any server. The conversion is instant and completely private.
