無料オンライン画像→SVGコンバーター | Fairmont AI

PNG・JPG・WebP・BMP・GIFをオンラインで無料SVGに変換。アップロード不要、ブラウザ上で動作。

An SVG (Scalable Vector Graphics) converter transforms raster images — photos and graphics made of pixels — into resolution-independent vector files. Unlike PNG or JPG files that blur when enlarged, SVG files are made of mathematical paths and shapes, so they look sharp at any size: on a business card, a billboard, or a 4K screen. Our free online SVG converter runs entirely inside your browser using advanced tracing algorithms. Your image is never uploaded to any server, and no account is needed.

How to Convert an Image to SVG (3 Easy Steps)

  1. Upload your image: Drag and drop your PNG, JPG, WebP, BMP, or GIF file into the upload area, or click to browse. The tool accepts images up to 10 MB.
  2. Choose your settings: Pick a Quality Preset (Detailed, Balanced, or Simple) and adjust the Colors slider. More colors produce a more faithful result; fewer colors yield a simpler, smaller SVG file.
  3. Convert and download: Click "Convert to SVG". The conversion happens instantly in your browser. Preview the result side by side with your original, then click "Download SVG" to save the file.

Frequently Asked Questions

Is this SVG converter really free?

Yes, completely. There are no credits, no subscriptions, and no watermarks. You can convert unlimited images at no cost.

Does my image get uploaded to your servers?

No. The entire conversion runs inside your browser using JavaScript. Your image never leaves your device, making this tool fully private.

What image formats does the converter support?

The tool supports PNG, JPG/JPEG, WebP, BMP, and GIF files up to 10 MB in size.

Will the SVG look exactly like my original image?

Vector tracing is an approximation — it works best on graphics with clear edges and limited colors, like logos, icons, and illustrations. Photographs with millions of subtle color gradients will be simplified and stylized rather than reproduced exactly. Adjust the Colors slider and Quality Preset to control the level of detail.

What is the maximum image size supported?

Files up to 10 MB are accepted. Very large images (over 1200×1200 pixels) are automatically scaled down before tracing to keep conversion fast and the output SVG manageable.

Can I use the SVG in Figma, Illustrator, or Inkscape?

Yes. The output is a standard SVG file that opens in all major design tools including Figma, Adobe Illustrator, Inkscape, Affinity Designer, and any browser.

Why does my SVG look different from the original?

SVG tracing converts continuous pixel data into discrete colored regions. Try increasing the Colors slider or switching to the "Detailed" preset to improve fidelity. For photos, a lower color count often produces a more visually appealing, stylized result.

Can I use the converted SVG commercially?

The converter itself imposes no restrictions. However, make sure you own the rights to the original image before converting and using it commercially.
