Question 1

What image formats does QRQuick convert between?

Accepted Answer

QRQuick converts PNG, JPG, WebP, GIF, and BMP inputs to PNG, JPG, or WebP outputs. Conversion runs in your browser using the canvas API.

Question 2

Are my images uploaded to a server?

Accepted Answer

No. Conversion happens entirely in your browser. Images never leave your device. QRQuick has no access to them.

Question 3

How does the quality slider work?

Accepted Answer

For JPG and WebP outputs the slider sets the encoder quality from 40% to 100%. Lower values produce smaller files with more visible compression. PNG output is always lossless and ignores the slider.

Question 4

Why does my JPG output have a white background?

Accepted Answer

JPG does not support transparency. When converting a transparent PNG or WebP to JPG, QRQuick fills the transparent areas with white so the result is viewable. Pick WebP if you need to keep transparency.

Question 5

Is there a file size limit?

Accepted Answer

There is no QRQuick-imposed limit. Practical limits depend on your browser's memory — most modern browsers handle images up to 50–100 MB comfortably.
