Frequently Asked Questions
Will converting JPG to PNG improve image quality?
No. Converting from JPG to PNG preserves the current quality but cannot recover detail already lost by JPG compression. It prevents further quality loss from re-saving.
Why is my PNG file larger than the JPG?
PNG uses lossless compression, which preserves all pixel data. This typically results in larger files than JPG, which discards some data to achieve smaller sizes.
Can I add transparency after converting to PNG?
The converted PNG will support transparency, but the image itself will not have transparent areas. You would need an image editor to remove backgrounds after conversion.
Is this converter free to use?
Yes, completely free with no limits. The conversion runs in your browser, so there are no server costs.
What is the maximum file size I can convert?
There is no strict limit since processing happens in your browser. However, very large images (50MP+) may be slow depending on your device.
How It Works
This converter uses your browser's built-in Canvas API to process files locally. Your JPG files are decoded and re-encoded as PNG entirely on your device. Nothing is uploaded to any server.
