How to svg precision tuner: technical faq and troubleshooting guide
- Step 1Start conservative — Begin at 2 decimal places and view the output at your intended display sizes. If it looks identical, try 1. Only use 0 for simple geometric icons.
- Step 2Check for curve distortion — Zoom in on smooth curves and circular arcs in the preview. Over-rounding shows as slight angularity on curves. If visible at 2×, go back to 2 decimal places.
- Step 3Test at mobile size — Most SVG icons are viewed at 16–48px on mobile. Distortions invisible at 200px zoom are usually invisible at real display sizes too.
Frequently asked questions
What is the minimum safe precision for smooth curves?+
1 decimal place for icons displayed at 16–64px. For SVGs displayed at 200px+ (hero illustrations, large logos), use 2 decimal places to prevent subtle curve distortion.
Are arcs (A path command) affected by rounding?+
Yes. Arc rx, ry, x-axis-rotation, large-arc-flag, sweep-flag, x, y values are all rounded. Rounding arc start/end coordinates can cause slight arc length changes on complex curves.
Can I selectively preserve precision for specific elements?+
Not in the UI — it applies globally. For element-level control, use SVGO's convertPathData plugin with the convertToZ, collapseRepeated, and leadingZero options configured in code.
What is the file size limit for the Precision Tuner?+
Same as the minifier: 5 MB on Free, 50 MB on Pro. The tool processes only text content, so even large SVG illustration files are handled quickly.
