There are online converters, just be aware that anything proprietary or unique will likely be stolen.

Inkscape is a decent vector graphic editor that is capable of converting raster to vector.

It all depends what you are trying to accomplish though. For 3D printing, I've often found that importing the jpeg into fushion360, and then tracing on a sketch plane, to give the best results for copying stuff like logos.

Yes   several AI-assisted and automated tools specialize in cleaning up messy photogrammetry (or scan) meshes into more regular, usable models. Photogrammetry outputs are typically noisy, high-poly triangle soup with floating debris, holes, non-manifold geometry, uneven density, and poor topology. No single model is perfect for every case (results still often need light manual polish for production work), but these stand out as particularly effective.
Strong Options for Cleanup + Retopology
Tripo AI / Tripo Studio (one of the most practical AI options right now)

Built-in retopology step (including Smart Low Poly / Smart Mesh) that takes a dense/messy input mesh and rebuilds it into cleaner triangle or quad topology with a controllable target polygon count.
Explicitly useful for photogrammetry and scan data: users feed in decimated or raw-ish scans and get a solid base mesh quickly.
Supports part-based processing, texture baking options, and export to common formats (OBJ, FBX, GLB, etc.).
Hybrid workflow recommended by practitioners: light pre-clean   Tripo retopo for the heavy lifting   final manual tweaks in Blender/Maya/ZBrush.
Good for organic forms, props, and turning scans into game/AR-ready assets.

Polyvia3D (excellent free/online one-click scan cleanup)

Browser-based tools specifically for photogrammetry and LiDAR scans (supports PLY, OBJ, STL, GLB).
Automated pipeline: remove floating debris/disconnected components, fill holes, fix degenerate/non-manifold geometry, optional Taubin smoothing for noise, and polygon reduction.
Fast (seconds to a minute), no install needed, and designed exactly for the common artifacts in RealityCapture, Metashape, Polycam, etc. outputs.
Great first-pass cleaner before more advanced retopology.

AutoRemesher (free, open-source, high-quality automatic quad remeshing)

Standalone tool (now MIT-licensed, v1.0) that converts dense/high-poly meshes (including photogrammetry) into clean quad-based topology.
Controls for target number of quads, adaptivity, sharp edges, and smooth normals. GUI + CLI.
Excellent for turning triangle soup into something more regular and usable for further editing, UVs, rigging, or games. Builds on solid libraries (Geogram, libigl, etc.).

Other notable tools

Blend Swap AI Mesh Cleanup: Upload scans or AI meshes   voxel remesh for watertight/manifold output + decimation to a target poly count. Simple and effective for print-ready or engine-ready results.
Instant Meshes (classic free open-source): Still widely used and recommended for photogrammetry cleanup/retopology. Fast isotropic remeshing with some user guidance (orientation fields) for better edge flow. Often paired with Blender.
Meshy / 3D AI Studio / Scenario: Offer remesh/retopo features (including Meshy Remesh) that work well on uploaded meshes. Useful if you're already in an AI-generation pipeline.
Subpixel: Specialized for turning noisy photogrammetry into CAD-friendlier geometry by detecting primitives (planes, cylinders, etc.) and logical part grouping   more reverse-engineering oriented than pure retopology.
Traditional strong options that remain highly effective: MeshLab, Blender (with addons like Quad Remesher, RetopoFlow, or Instant Meshes integration), Geomagic Wrap, or Artec Studio for more industrial/precision work.

Practical Recommended Pipeline

Initial cleanup   Polyvia3D, MeshLab, or Blender (remove floaters, fill major holes, basic repair).
Retopology / regularization   Tripo AI (Smart Low Poly/quad option) or AutoRemesher/Instant Meshes for a clean, lower-poly base with better topology.
Polish   Manual sculpt/retopo touch-ups + normal/detail baking from the original high-poly scan + UV/texture cleanup.
Export for your target use (print, game engine, CAD, etc.).

Limitations: Pure end-to-end "perfect usable model" AI is still maturing. Complex hard-surface objects, animation-ready edge flow, or precise CAD parametric results usually need human oversight. Texture artifacts from photogrammetry may also require separate inpainting or re-baking.
For most people working with photogrammetry right now, Tripo AI's retopology tools or a Polyvia3D + AutoRemesher/Instant Meshes combo give the best balance of automation, quality, and accessibility. If you share more details (organic vs hard-surface, target poly count, end use like printing/games/CAD, or preferred software), I can refine the recommendation further.

I found one a while ago but can't remember the name of it.
I have a site to change a jpeg to an svg file.
