Frequently Asked Questions

Is it really free to convert JPG to PNG?

Yes, absolutely! Our JPG to PNG converter is completely free with no limitations on file size, number of conversions, or features. No registration or payment required.

Will my images be uploaded to a server?

No! All image conversions happen locally in your browser using HTML5 Canvas technology. Your images never leave your device, ensuring complete privacy and security.

What's the difference between JPG and PNG?

JPG uses lossy compression, making it great for photos but it doesn't support transparency. PNG uses lossless compression and supports transparent backgrounds, making it ideal for logos, graphics, and images with text. You might also want to check our JSON formatting tools for data conversion needs.

Will converting JPG to PNG improve image quality?

Converting JPG to PNG won't restore quality lost from JPG compression, but it will prevent further quality loss. PNG's lossless format is better for images that need to be edited multiple times or require transparency.

Can I convert multiple JPG images at once?

Currently, the converter processes one image at a time for optimal quality and performance. However, you can quickly convert multiple images by using the "Reset" button after each conversion.

What file size limits are there?

The converter handles images up to 50MB and dimensions up to 16,384 pixels (the browser's maximum canvas size). This covers everything from tiny icons to large high-resolution photos. Processing happens instantly in your browser using optimized Canvas API with high-quality image smoothing.
