À propos de la vectorisation
La vectorisation recrée des chemins SVG à partir des pixels de l'image. Elle ne garantit pas une reproduction parfaite de l'original. Les photos, détails de cheveux, gradients complexes et images très détaillées ne conviennent généralement pas à une conversion SVG propre.

What is Image Vectorization?
Image vectorization is the process of converting raster images (made of pixels) into vector graphics (made of mathematical paths). Unlike raster images that become blurry when scaled, vector graphics can be resized to any dimension without losing quality. This makes SVG files ideal for logos, icons, and graphics that need to appear at multiple sizes.
PNG/JPG vs SVG
PNG and JPG are raster formats that store images as a grid of colored pixels. They have fixed dimensions and become pixelated when enlarged. SVG (Scalable Vector Graphics) stores images as mathematical descriptions of shapes, lines, and colors. SVG files are resolution-independent, can be edited with code, and typically have smaller file sizes for simple graphics.
True Vectorization vs Bitmap Embedding
True vectorization analyzes the image pixels and generates actual SVG path elements (<path>, <polygon>, <circle>) that recreate the visual appearance. Some tools simply embed the original image as a Base64-encoded bitmap inside an SVG wrapper - this is NOT vectorization. Our tool generates real vector paths, ensuring your SVG is truly scalable and editable.
Which Images Work Best?
The best candidates for vectorization are images with clear edges, solid colors, and simple shapes: logos, icons, signatures, stamps, line art, QR codes, paper cut patterns, simple cartoons, and web icons. Images with many colors, gradients, or fine details (like photographs) will produce complex SVGs with many paths and large file sizes.
Why Don't Photos Convert Well?
Photographs contain millions of subtle color variations, gradients, and fine details. Converting these to vector paths would require thousands or millions of path nodes, resulting in huge SVG files that are slow to render. Photos also lack the clear edges and solid color regions that vectorization algorithms rely on. For photos, consider using our Image Compressor or Image Format Converter instead.
How to Improve Logo Vectorization
For best results: 1) Start with a high-resolution source image (at least 512×512 pixels). 2) Use images with clear, sharp edges and solid colors. 3) Remove complex backgrounds before vectorizing. 4) Choose B&W mode for monochrome logos, Color mode for multi-color designs. 5) Adjust the threshold and smoothing parameters to balance detail and file size. 6) Use the Fine quality preset for production-ready results.
B&W Mode vs Color Mode
B&W (Black & White) mode converts the image to a binary silhouette, perfect for signatures, stamps, monochrome logos, and line art. It produces clean, simple SVGs with one path. Color mode preserves multiple colors by quantizing the image into a limited palette (2-32 colors) and creating separate paths for each color region. Use Color mode for flat logos, simple illustrations, and multi-color icons.
How to Reduce SVG File Size
To create smaller SVG files: 1) Use fewer colors in Color mode (4-8 instead of 16-32). 2) Increase path simplification to reduce node count. 3) Use the Fast quality preset for web previews. 4) Remove unnecessary details with higher despeckle values. 5) Use B&W mode when color isn't needed. 6) Enable SVG compression in the download settings. Note: smaller files may lose some visual detail.
Can SVG Scale Infinitely?
Yes! SVG files are resolution-independent because they describe shapes mathematically rather than storing pixel data. You can scale an SVG from favicon size (16×16) to billboard size (10×10 meters) without any loss of quality. This is why SVG is the preferred format for logos, icons, and graphics that need to appear at multiple sizes across different devices and media.
Will My Image Be Uploaded?
No. All processing happens entirely in your browser using JavaScript and Web Workers. Your image never leaves your device - it is not uploaded to any server, not stored anywhere, and not sent to any third party. When you close or refresh the page, all image data is cleared from memory. We cannot see, access, or store your images.
Frequently Asked Questions
What is an SVG file?
SVG (Scalable Vector Graphics) is an XML-based vector image format. Unlike PNG or JPG which store pixels, SVG stores mathematical descriptions of shapes, making it infinitely scalable without quality loss.
Can I convert any image to SVG?
While any image can be processed, results vary greatly. Simple graphics with clear edges (logos, icons, signatures) convert well. Complex photos with gradients and fine details produce large, complex SVGs that may not be practical.
Is the output a real vector file?
Yes. Our tool generates actual SVG path elements (<path>, <polygon>, etc.) by tracing the image contours. The output does not contain embedded bitmaps or Base64-encoded images.
What's the difference between B&W and Color mode?
B&W mode creates a single-color silhouette, ideal for signatures and monochrome logos. Color mode preserves multiple colors by creating separate path layers for each color region.
Why is my SVG file so large?
Complex images with many colors and details require more path nodes. Try using fewer colors, increasing path simplification, or switching to B&W mode for simpler results.
Is my image uploaded to a server?
No. All processing happens in your browser. Your image never leaves your device and is not stored or transmitted anywhere.
