Frequently Asked Questions
Is the quality maintained after conversion?
Yes, PNG is a lossless format. While it won't magically improve a low-quality JPG, it will perfectly preserve the image data without introducing new artifacts.
Why is the PNG file size larger?
JPG uses compression that discards some data to save space. PNG preserves every pixel perfectly. When converting a compressed JPG to PNG, the file size often increases because you are saving "noisy" compressed data in a high-fidelity format.
Does it work on mobile phones?
Absolutely! Our tool works on any modern browser, including Chrome, Safari, and Firefox on Android and iOS devices.
