Frequently asked questions
What quality should I start with?
Try 75–85 for photos and inspect the actual image at a larger size.
Is PNG transparency preserved?
WebP preserves alpha when the browser supports that output.
Is the image uploaded?
Conversion runs in the browser; the selected file is not sent to QR64Code servers.
