Browser-local SVG Processing

The Fix Size utility processes SVG content in your browser. The raw SVG is not uploaded for processing; actual processing time depends on the file and your device. See the Privacy Policy for normal website requests and hosting logs.

About Fix Size

Missing viewBox definitions or mismatched width and height attributes cause SVGs to render incorrectly or scale poorly on responsive websites. This utility fixes viewport scaling issues by establishing correct coordinate spaces and repairing sizing nodes based on document bounds. It ensures your vector graphics scale crisply across all screen dimensions.

How It Works

01

Paste your SVG code.

02

The engine calculates coordinate dimensions and establishes a viewBox.

03

Copy or download the updated SVG.

Sizing repair notes

Fix Size targets SVGs whose width, height, or viewBox relationship causes cropping, unexpected scale, or layout alignment problems. Make a copy first because changing the viewport can reframe artwork even when path coordinates remain unchanged.

What this tool does

  • Inspects sizing attributes and establishes or repairs a coordinate space for supported SVG structures.
  • Helps create a viewBox when the source contains dimensions or geometry that can be used as a starting point.
  • Returns an SVG that can be tested with responsive CSS or explicit image dimensions.

Review before publishing

  • Inferring bounds cannot know whether shadows, filters, strokes, or off-canvas artwork are intentionally visible.
  • A repaired viewBox can change cropping or whitespace; compare the preview with the original.
  • For complex illustrations, manual inspection of the target browser and component wrapper is still required.

Before

<svg width='240' height='120'><path d='M10 10h220v100H10z'/></svg>

After (illustrative)

<svg width='240' height='120' viewBox='0 0 240 120'><path d='M10 10h220v100H10z'/></svg>

Frequently Asked Questions

Why does my SVG disappear when scaled in CSS?

If the vector doesn't have a defined viewBox attribute, browsers cannot calculate how to scale paths. Adding a proper viewBox fixes this scaling issue.

Does this tool scale the vector paths?

No, it repairs the document attributes so the viewport handles scaling dynamically, leaving the coordinates intact.

What if my SVG doesn't have width or height set?

The repair tool infers coordinate dimensions from existing paths or applies a standard fallback viewBox space.
