Vectorization.org converts images to black-and-white vector artwork. It can produce real SVG paths, but keeping the `.svg` extension does not mean keeping the original colors or every small feature. Use the service when a monochrome interpretation suits the image, then compare the saved result with the source before using it.

The service's [About page](https://www.vectorization.org/about.html) explicitly says color images are converted to black and white. Our actual RGB PNG test saved an SVG with three black paths and no embedded image. The source's navy and teal became black, while its gold rectangle was absent from the result.

## Decide what must survive without color

A monochrome trace uses one foreground color to describe the artwork. That can suit a silhouette or a drawing intended to appear in black. It cannot preserve a distinction that depends on a teal shape remaining teal and a gold shape remaining gold.

Before uploading, identify the largest silhouette, any interior opening and the smallest intentional mark you need. If color separates overlapping regions or carries meaning, write that requirement down too. A clean-looking black preview can still be unsuitable when an important source region disappears.

You need a permitted source image, a retained original, a web browser and a place to save the SVG. Keep the original available for comparison rather than judging only the returned preview. This guide follows the browser service at [vectorization.org](https://www.vectorization.org/), not a local tracing command.

**Method:** On November 8, 2026, we uploaded our original 384 × 256 **RGB color PNG** with an opaque white background. It contained a navy rectangular frame, a teal triangle, a gold rectangle and navy squares measuring 2 × 2 and 8 × 8 source pixels. We selected SVG output and saved the actual result. This was one color-control test, not a grayscale scan, a varied-image benchmark or a physical-output test.

## Upload your image and save the actual SVG

The current [homepage form](https://www.vectorization.org/) provides a file upload, a URL alternative, an output-format choice and **Start**. Our run used the local file upload and SVG. We did not observe or adjust a threshold slider in that form.

1. Use **Upload a file** to choose your permitted image.
2. Confirm that the selected filename is the one you intended. Keep the source unchanged for comparison.
3. Choose **SVG** as the output format.
4. Select **Start** and wait for the **Result** page.
5. Open the named `.svg` result link and save the actual file, rather than treating the displayed preview as your deliverable.
6. Compare the saved artwork with the original: check the silhouette, openings, intentional marks and regions previously distinguished by color.

Our Result page showed the named SVG link above and below the preview, with **Back to start** beneath it. We retained the linked 852-byte SVG. The screenshot below is the actual returned artwork, cropped to remove the browser chrome and advertisement.

*The actual monochrome result from our RGB control. The gold rectangle and 2 × 2 navy square are absent; the frame opening, triangle and larger square remain visible.*

If no result link appears, retain the source and check the service's current upload requirements before trying again. Do not substitute an advertisement or a screenshot for the missing SVG. If the result opens but an important region is missing, return to the original and decide whether a different source preparation or a color-preserving tracing route fits the job.

## Separate real geometry from preserved meaning

XML inspection of our saved file found **three `<path>` elements**, no `<image>` element and an inherited black fill of `#000000`. Those are real path shapes in this particular export. The [SVG paths specification](https://www.w3.org/TR/SVG2/paths.html) describes path geometry, including paths with multiple subpaths.

A subpath is a separate contour within a path. The frame in this output used an outer contour and an interior contour within the same path, retaining its visible opening. Three path elements therefore did not mean three solid, hole-free pieces, or one element for every original colored region.

| Source feature             | Observed saved result                | Check for your own image                 |
| -------------------------- | ------------------------------------ | ---------------------------------------- |
| Navy frame with an opening | Black frame with the opening visible | Does the important interior gap remain?  |
| Teal triangle              | Black triangular shape               | Is losing its color acceptable?          |
| Gold rectangle             | Absent                               | Has a meaningful region disappeared?     |
| 2 × 2 navy square          | Absent                               | Was it noise or an intentional detail?   |
| 8 × 8 navy square          | Present as black geometry            | Does the smallest required mark survive? |

These observations do not establish a universal size cutoff or explain the service's threshold algorithm. The two squares show what happened to those specific marks in this specific file. They do not prove that every detail below a certain size will disappear, or that every larger feature will survive.

For mixed or unexpected SVG content, our [SVG raster-image inspection guide](https://perfectvector.com/blog/svg-contains-raster-image) explains how to distinguish geometry from an embedded picture. For a broader visual check, use the [trace-quality checklist](https://perfectvector.com/blog/evaluate-vector-trace-quality) to compare the important features rather than relying on file size or path count.

## Check the saved document before the next task

Our SVG declared a width of `320.918109pt`, a height of `193.140091pt` and `viewBox="0 0 320.918109 193.140091"`. The source was 384 × 256 pixels. These are the observed export attributes; this single run does not establish a universal scaling or cropping rule for the service.

The viewBox specifies a coordinate region used to map the artwork into its viewport, as defined by the [SVG coordinate-system specification](https://www.w3.org/TR/SVG2/coords.html#ViewBoxAttribute). For a size-sensitive destination, check the imported document and intended dimensions there. Do not assume the source pixel numbers and exported point dimensions are interchangeable.

Before accepting your file, open a copy in the intended receiving app, confirm the artwork appears, and check selection and dimensions. We did not perform that native-app check, edit the geometry, import it into a cutter or make a physical sample. Our demonstrated endpoint is the actual browser result and saved monochrome SVG.

The saved document also contains metadata reading `Created by potrace 1.12`. That is a statement in this file's metadata, not independent verification of the current software installation behind the service. There is no need to infer a hidden setting or reproduce a local command to follow the browser steps above.

## Choose another route when color carries the design

PerfectVector is a useful next option when you want to inspect a candidate image-to-vector trace while checking separate color regions, contours and interior openings. Start with your original image on the [image-to-vector page](https://perfectvector.com/image-to-vector), then judge those requirements in its preview. We did not convert this control with PerfectVector or run a paired comparison.

PerfectVector's [product facts](https://perfectvector.com/product-facts.md) describe a free view-only preview, with editing and export after unlocking. If the monochrome result already suits your artwork, use that route and check its saved file. If the source requires exact construction or the trace misses essential details, manual drawing may be the more suitable next step.

For drawings where the main concern is the difference between filled outlines and a single drawn line, continue with the [line-art tracing guide](https://perfectvector.com/blog/line-art-to-svg). That is a separate decision from whether this service retains the colors and features of your source.

## FAQ

**Does Vectorization.org preserve color images?**
No. Its About page says images are converted to black and white. Our RGB control returned black paths, with some original regions absent.

**Can I adjust a threshold slider in the demonstrated form?**
No threshold slider was observed or adjusted in our browser run. The visible form provided source input, output format and Start. This guide does not supply a hidden threshold value.

**Was the downloaded SVG just an embedded PNG?**
No. Our actual saved file contained three path elements and no image element. That establishes geometry for this export, not acceptance in an untested editor or cutter.

**Does a small black detail always disappear?**
This test does not establish a general cutoff. The 2 × 2 source square was absent and the 8 × 8 square remained, but other images and details were not tested.
