Why Convert JPG to PNG?
PNG is a lossless format that preserves all image data without quality loss. Unlike JPG, PNG supports transparency and produces crisp, detailed images ideal for graphics, logos, and web design. Convert to PNG when you need transparency support, lossless quality for editing, or archival storage. Note: PNG files are typically larger than JPG, but offer better quality and flexibility.

Frequently Asked Questions
Will my PNG be larger than the original JPG?
Likely yes. PNG uses lossless compression while JPG uses lossy compression, which typically results in smaller file sizes. However, PNG provides better quality and supports transparency. Choose PNG when quality and flexibility are more important than file size.
Can I convert multiple files at once?
Yes. Upload multiple JPG files and they will all be converted with the same settings. Single files download directly, multiple files are automatically packaged into a ZIP archive.
What's the file size limit?
Each JPG can be up to 50 MB. Total conversion size depends on your browser's available memory, but typically you can convert files totaling several hundred MB.
Are my images uploaded to a server?
No. All conversion happens locally in your browser using the Canvas API. Your images never leave your device, ensuring complete privacy and security.
Can I convert JPG to PNG on mobile?
Yes. This tool works on desktop, tablet, and mobile browsers. Just tap to select files and convert.
What about JPG vs PNG quality?
PNG conversion preserves the image quality of the original JPG. Since JPG is already lossy, converting to PNG won't restore lost detail, but it prevents further quality loss if you need to edit the image.
