Key Features & Capabilities

Our API is powered by an intelligent vectorization engine to deliver high-quality, editable vector graphics.

Simple User Interface

AI-Powered Vectorization

Utilize advanced algorithms that analyze your PNG, identify shapes and color boundaries, and intelligently trace them into clean vector paths.

Simple Data Format

Infinitely Scalable Output

The primary benefit of SVG. The output file can be scaled to any dimension—from a tiny icon to a giant billboard—with absolutely no loss of quality or pixelation.

Time

Color Palette Control

Our online converter allows you to extract data from images and convert it into Excel format in just three easy steps.

Secure Data

Transparency Preservation

The transparent background of your source PNG is fully preserved, resulting in an SVG with a transparent background suitable for overlaying on any design.

Universal Access

Optimized SVG Paths

The API generates smooth, optimized SVG code with a minimal number of anchor points, making the final files lightweight and easy to edit.

Freedom

Secure & Confidential

All images are processed over encrypted connections. We guarantee confidentiality with a strict data privacy policy and do not store your files.

Frequently Asked Questions

Find answers to common questions about our PNG to SVG API to understand the vectorization process and its best use cases.

This process is called "image tracing" or "vectorization." Instead of storing pixels (like a PNG), an SVG stores mathematical paths and shapes. Our API's algorithms analyze the pixels in your PNG to identify edges and color areas, then draw vector paths to recreate the image.

Images with clear lines, distinct shapes, and solid colors work best. This includes logos, icons, clipart, and simple illustrations. Complex, photorealistic images can be converted, but the result will be a stylized, artistic interpretation rather than a true photo.

For simple graphics like logos, the result will be extremely close and clean. For complex images, the SVG is a "vector interpretation." It's not a perfect pixel-for-pixel copy but a new, scalable version of your image built from shapes.

Yes. That's a major benefit of SVG. The output file is fully editable in any vector graphics software like Adobe Illustrator, Inkscape, Figma, or Sketch. You can change colors, adjust shapes, and modify paths.

These options help you control the final output. Reducing the `color_count` simplifies the image and can create a cleaner, more stylized look. The `detail_level` controls how closely the algorithm follows the original shapes, with 'high' creating more complex paths and 'low' creating simpler ones.

The main reason is scalability. SVGs are resolution-independent and look sharp on any screen, including high-DPI "Retina" displays. They also often have smaller file sizes for simple graphics and can be manipulated with code (CSS/JS).

Absolutely. We use end-to-end TLS encryption for all data transfers. Your image files are processed securely and are permanently deleted from our servers immediately after the conversion is complete.
