Convert Numbers to Image

Three main reasons: (1) Anti-scraping – public phone numbers / emails / IDs displayed as images can’t be easily harvested by bots. (2) Visual designs – watermarks, badges, invoice serial numbers. (3) Cross-platform consistency – an image renders identically on every device, while live text depends on the viewer’s font availability.

Binary search on font size. The tool measures the text at your chosen font size; if it overflows, it tries half the size; if it fits, it tries 75%; and so on until it finds the largest size that fits the canvas width minus padding. Final size shows in the stats line. Always ≥ 12 px (minimum readable).

The canvas backing store is scaled by window.devicePixelRatio (capped at 3×). A 800×200 logical image renders into a 1600×400 buffer on a 2× display, then CSS shrinks the displayed size back. So text edges stay sharp instead of looking pixelated. Older tools that ignore DPR produce blurry text on the same Retina machines.

The color picker doesn’t expose an alpha channel – backgrounds are solid color. Workaround: pick a background color that matches your destination surface, then no extra editing needed. For true transparency, generate with white background and use an image editor to remove it.

Yes – the input field accepts any text. The tool name says “numbers” because that’s the common case, but it renders any string. Useful for short IDs that mix letters and digits (ORD-2024-A5B3).

Width 2000 px, height 1000 px (logical). With DPR=3, the actual backing-store is up to 6000×3000 px which is fine for any browser. Larger sizes would risk hitting browser canvas memory limits.

So you can use them independently. Bold alone is common for emphasis. Italic alone is rare but useful for “this number is a variable / reference”. Both together also works (bold italic). Both off is the default.

Almost never for text. PNG is lossless – the text edges stay perfectly sharp. JPEG introduces compression artifacts that show up as ringing/halos around letters, even at 95% quality. Pick JPEG only if file size matters more than visual quality AND the rest of the image is photographic.

No. All Canvas rendering, font measurement, and image encoding happens in your browser. Open DevTools → Network and confirm zero requests fire after the page loads. Safe for sensitive numbers like account IDs, internal codes, or proprietary serial numbers.

Yes. Total bundle is under 22 KB. Once loaded, disconnect and keep generating images. Useful for prepping printable codes or watermarks in air-gapped environments.
