Frequently Asked Questions

Will the PNG be larger than the JPG?

Yes, typically. PNG uses lossless compression, so the file size is usually larger than the original JPG. The trade-off is that PNG preserves full image quality with no further compression artifacts.

Does converting JPG to PNG improve quality?

No. Converting from JPG to PNG does not recover quality lost during the original JPEG compression. It simply stores the existing pixels losslessly, preventing any additional quality degradation from future saves.

Is my image uploaded to a server?

No. All conversion happens in your browser using the HTML5 Canvas API. Your image is never sent to any server and stays completely private on your device.
