 - `fill` or `nofill`: fill empty space between icon and text, default: `fill`
 - `qrfirst` or `textfirst`: switch position of QR-Code and text block, default: `qrfirst`
 - `https` or `www`: should links in the hints be prefixed with `https://` or `www.`, default: `https`
-- `qreclevel=`: QR error correction level `L`, `M`, `Q`, or `H`, default: `Q`. Increase to `H` if you use `photoinqr=true` or expect minor print noise.
-- `photoinqr` or `nophotoinqr`: place photo in the center of the QR code (`photoinqr`) instead of next to the name, default: `nophotoinqr`. **Requires `qreclevel=H` for reliable scanning**, as the photo occludes part of the QR code (~15% by default).
-- `qrlogoscale=`: relative size of the photo overlay in QR code (when `photoinqr=true`), as fraction of QR code width, default: `0.15` (15%). Higher values may reduce scannability.
-- `qrlogoborder=`: white padding around the photo overlay (when `photoinqr=true`), as fraction of QR code width, default: `0.02` (2%). Increases contrast and readability for scanners.
+- `qreclevel=`: QR error correction level `L` (~7%), `M` (~15%), `Q` (~25%), or `H` (~30%), default: `Q`. Use `H` when `photoinqr=true`.

+- `qrlogoscale=`: photo size in QR code as percentage of QR width (0-100), default: `25` (25% width = 6.25% area). Recommended values: Level H: 25-30%, Level Q: 20%, Level M: 15%, Level L: 10%. Higher values may reduce scannability.
+- `qrlogoborder=`: transparent padding around photo in QR code as percentage of QR width (0-100), default: `2` (2%). Adds space between photo and QR modules.

+- Always use `qreclevel=H` (highest error correction ~30%) for reliable scanning
 - Test QR code scannability with multiple apps before printing
-- Start with `qrlogoscale=0.15` and `qrlogoborder=0.02`; if scanning fails, try `qrlogoscale=0.12` or `0.10`
-- The photo is placed on a white rounded rectangle background to preserve contrast
+- Default `qrlogoscale=25` (25% width = 6.25% area) is recommended for Level H
+- If scanning fails, reduce to `qrlogoscale=20` or `qrlogoscale=15`
+- PNG transparency is preserved - use images with transparent backgrounds for best results
