Raster to SVG: which AI vectorizer to use and when

SVG is a great format until you ask it to do the wrong job.

It is excellent for logos, icons, line art, flat illustrations, badges, labels, simple maps, UI assets, and anything that should stay crisp when it moves from a tiny web button to a large print layout. It is much less magical with photos, painterly textures, glass reflections, soft shadows, and busy screenshots. Those details are built from pixels. SVG wants shapes.

That is the first decision to make before choosing a vectorizer: are you converting an existing raster image, or are you trying to create a new vector from scratch?

Those sound close. In practice, they are different workflows.

Two workflows people mix up

Raster-to-SVG conversion starts with an image file. You upload a PNG, JPG, or similar source, and the tool traces the visible forms into vector paths. This is what most designers mean when they say they need to vectorize a logo.

Prompt-to-SVG generation starts with text. You describe an icon, badge, mascot, label, or illustration, and the model generates a vector image directly. There is no original raster file to trace.

The first workflow is restoration or conversion. The second is creation.

I would not treat them as interchangeable. If you already have a clean logo in PNG form, converting it is faster and usually more faithful than describing it from memory. If you have only a vague idea for a sticker, prompt-based vector generation makes more sense than generating a raster image and tracing it afterward.

What vectorization can and cannot preserve

Vectorization turns pixel regions into geometric shapes: curves, lines, fills, and sometimes a lot of tiny paths. That is why simple graphics convert so well. A flat icon has clear edges and a small number of colors. A wordmark has hard contrast. A pen sketch has obvious strokes.

Good candidates include logos, scanned sketches, monochrome line drawings, app icons, product badges, simple diagrams, flat character art, and illustrations with a limited palette.

Bad candidates include portraits, product photos, architecture shots, glossy 3D renders, watercolor textures, dense UI screenshots, and anything where the important detail is a soft transition rather than an edge. A vectorizer can still return an SVG, but the result may be heavy, noisy, or visually wrong.

That is not a failure of one provider. It is the format doing what the format does. SVG is built for scalable geometry. A photograph is built from continuous tone. To represent every subtle tonal change as paths, the file either gets bloated or the image gets simplified.

The blunt rule: if the original probably began life in Illustrator, Figma, Sketch, or a logo design tool, try raster-to-SVG conversion first. If it came from a camera, 3D renderer, or heavily textured illustration workflow, expect cleanup work.

The raster-to-SVG options

For image conversion, the two practical choices here are Recraft Vectorize and Picsart Image Vectorizer.

Recraft Vectorize is the cheaper starting point. Recraft's current API pricing lists image vectorization at about one cent per request. Recraft's own vectorizer guidance focuses on turning PNG and JPG artwork into editable SVG output, with controls that help reduce colors and simplify complex images. In plain use, that makes it a strong first pass for logos, icons, flat artwork, and legacy brand assets that were exported to raster by mistake.

Picsart Image Vectorizer is also built for raster-to-SVG conversion. Picsart describes it as a tool that converts pixel information into vector graphics using curves and lines, and its public pricing page lists the vectorizer as a 12-credit image service. Depending on the credit package, that can land around a few cents per image. Through the model examples surfaced by Runware, the visible task cost is about four cents per request.

The real difference is not philosophical. Both tools trace raster input into SVG. Recraft is the obvious first test when cost matters or when you have a batch of similar assets. Picsart is worth trying when the first result misses edge separation, flat color regions, or shape boundaries that matter to the design.

For one-off work, the price gap is tiny. For a folder of several thousand product badges, it is not.

The prompt-to-SVG options

Prompt-based vector generation is a better fit when you are designing something new.

Recraft V4 Vector generates SVG artwork directly from a text prompt. Recraft says V4 was released in February 2026 and positions the vector version for editable, production-quality SVG graphics with scalable geometry and discrete color regions. The current API price is about eight cents per image.

Recraft V4 Pro Vector is the higher-detail tier. Recraft lists it at about thirty cents per image, with longer generation time and a stronger fit for high-fidelity production work. I would reach for it when the asset has to survive serious review: packaging marks, campaign illustrations, large-format print pieces, polished icon families, or brand work where small contour problems will be noticed.

That does not mean Pro should be the default. Most early exploration does not deserve the expensive tier. Start with Recraft V4 Vector, decide whether the composition is worth keeping, then move up only when the idea is already close.

This is where prompt-to-SVG has a real advantage over tracing. A generated vector can be born with simpler shapes, cleaner regions, and a clearer visual hierarchy. A traced SVG is always negotiating with the source image.
