Pictostl - AI-powered JPG to STL converter for turning 2D images into 3D printable models directly in your browser

Core Features

Pictostl runs entirely in your web browser, no local 3D modeling software installation required. It supports input of JPG, PNG, and WebP image formats, and exports final 3D assets as either STL for 3D printing (geometry only) or GLB to retain full color textures. Users can upload multiple photos of the same object taken from different angles, which gives the AI more visual data to reduce guesswork for hidden surfaces and produce more detailed and accurate 3D meshes. Three distinct quality tiers are available for generation:

1. Basic: Lightweight output with 15,849 vertices, 18,690 faces, 1024 × 1024 color texture, 0.93 MB STL file size, intended for quick drafts and fast previews.

2. Pro: Mid-tier output with 783,028 vertices, 1,497,882 faces, 2048 × 2048 color, metallic/roughness and normal maps, 74.89 MB STL file size, for most standard 3D printing use cases that need rich detail.

3. Ultra: Highest detail output with 1,010,881 vertices, 1,933,489 faces, 4096 × 4096 color, metallic/roughness and normal maps, 96.67 MB STL file size, for projects that require maximum surface detail. All generated models can be inspected in the interactive 3D preview window, where users can rotate, zoom, and switch between Original (textured), Solid (untextured geometry), and Wireframe (mesh face edges) views to check shape quality before download. Users can also set the maximum edge length in millimeters to define the exact physical size of the exported STL file, which eliminates unit scaling issues common with raw STL files in 3D slicers.

Standard Workflow

The full conversion process takes 3 simple steps:

1. Upload your clear, well-lit 2D photo. For best results, upload multiple photos of the same object from front, back, left, and right angles with consistent lighting and background.

2. Select your desired quality tier between Basic, Pro, or Ultra, and confirm the required credit cost before generation starts.

3. Inspect the generated 3D model in the interactive preview, set your target physical size in millimeters, then download your STL or GLB file.

Pricing and Usage Rules

After account verification, every user gets 2 free credits, which is enough to run one full Basic quality generation and STL download. Additional generations require purchase of extra credits. The AI generates 3D shapes by interpreting light, shadow, and visual cues from input photos. It makes educated guesses for surfaces that are not visible in any uploaded image, so the output is not a dimensionally accurate 3D scan. You should always inspect the final geometry and confirm dimensions in your slicer before starting a 3D print. STL files do not store color or texture data, all texture and color information will only be retained in exported GLB files.
