Bitmap to Vector Online Tool · Free Raster Tracing
PolySVG Bitmap to Vector Converter turns pixel-based images (PNG, JPG, WEBP, BMP and more) into SVG vectors described by mathematical paths, so they stay sharp when enlarged. The in-house model handles color quantization, contour tracing and Bézier curve fitting, with the icon preset as the default for graphic assets and photo, logo and line art presets available as well. Free with no registration, and the result can be downloaded or refined in the editor.

功能亮点
Every bitmap format
PNG, JPG, WEBP, GIF, BMP and clipboard screenshots can all be uploaded, so a single entry point covers every vectorization job.
Five preset modes
Photo, icon, logo, line art and outline presets each optimize the parameters, and the default icon preset produces clean, crisp graphics.
Fine-grained control
Tune the color count, smoothing and detail strength freely, compare a few generations and trade off fidelity against file size.
Five preset modes
Choose photo, icon, logo, line art or outline by asset type for a better result.
A closed editing loop
Send the result to the editor to remove backgrounds, delete paths, touch up with the brush and recolor, then export SVG or PNG.

常见问题
What is the difference between a bitmap and a vector image?
A bitmap records an image as a grid of pixels and gets jaggy when enlarged; a vector image describes shapes with mathematical paths and stays sharp at any zoom. Vectorizing is the process of redrawing those pixel contours as paths.
Can a vectorized bitmap be scaled up infinitely?
Yes. The converted SVG consists of paths and curves, so it never blurs no matter how far you zoom — ideal for print, large displays and engraving.
Which of the five presets should I use?
Icons and graphics want the icon preset, marks want the logo preset, photos want the photo preset, handwriting and scans want line art, and extracting contours from a photo wants the outline preset. If you are unsure, start from the default and adjust based on the result.
Can the result be used for laser engraving directly?
Yes. SVG paths are widely accepted by engraving and vinyl-cutting software. Delete the leftover speck paths in the editor afterwards so the tool path stays clean.
Does this tool cost anything? Do I need to download software?
Completely free and ready to use in the browser — no registration and no software to install.
