Vector SVG export
Lines come out as real vector paths — scale infinitely, restyle, and color them in Illustrator, CAD, or any vector tool.

SVG is vector and contains the line paths only — scale, recolor, and edit it freely in Illustrator or CAD. PNG is exported on a white background.
Structure-first lines
Tuned to favor main building edges, openings, and outlines while suppressing texture, reflections, and foliage noise.
Local & private
Your photos never leave your device. All tracing happens locally in your browser.
Automatic & fast
Drop a photo and get a clean line drawing instantly — no manual tracing. Adjust a few sliders and export.
Who uses ArchitectLine?
Built for architecture, design, and real-estate professionals who need line art as an editable asset — not a finished filter.
Architects

Real Estate
Create stylized line illustrations of listings for brochures, flyers, and property graphics.
Illustrators & CAD Users
Import the SVG as a clean starting layer for vector illustration, drafting, and detailing.
Urban & Landscape Planners

Students & Educators
Produce line references and study sheets from photographs for analysis and drawing practice.
Frequently Asked Questions
Can I export the line drawing as a vector SVG?
Yes. SVG export is the core of ArchitectLine. The detected lines are traced into real vector paths, so you can scale them without quality loss and edit them in Illustrator, Inkscape, or CAD software. The SVG contains the line paths only. A PNG export (on a white background) is also available.
How does it avoid turning texture and noise into lines?
ArchitectLine favors strong, connected structural edges — building outlines, corners, and openings — and discards short, weak fragments from wall texture, reflections, and foliage. Use the Edge sensitivity and Noise reduction sliders to tune how much detail is kept.
Does it add any color?
No. ArchitectLine outputs black lines on white only. It is designed to produce a clean line asset you color and finish yourself in post.
Is my photo uploaded to a server?
No. All processing happens entirely in your browser. Your files never leave your device and are never sent to any server.
Is ArchitectLine free?
Yes, completely free. No account required, no usage limits, no watermarks.
Which file formats are supported?
You can import JPEG, PNG, and WebP photos, and export SVG (vector) or PNG.
How to Use ArchitectLine
From Photo to Line Drawing in 3 Steps
- Upload a building photo — Drop a JPEG, PNG, or WebP. Straight-on shots of facades and buildings with clear edges trace best.
- Tune the lines — Use Edge sensitivity to control how many lines appear, Noise reduction to drop texture and clutter, Smoothing to clean up the paths, and Line weight for stroke thickness.
- Export — Download a vector SVG to edit in Illustrator or CAD, or a PNG to drop straight into a layout.
Getting Clean Structural Lines
Photographs of buildings carry a lot of visual noise — wall texture, reflections, shadows, and plants. A naive edge filter turns all of it into lines. ArchitectLine prioritizes long, connected structural edges and discards short fragments, so the result reads as a building rather than a tangle.
If important edges are missing, raise Edge sensitivity. If the drawing is too busy, raise Noise reduction and Smoothing. Because the output is vector, you can always thin, thicken, or delete individual paths afterward in your editor.
Why Your Photos Never Leave Your Device
ArchitectLine runs entirely in your browser using the Canvas API. Your photo is never uploaded, never stored, and never used to train any model. The moment you close the tab, the image is gone.
That makes it safe for client projects, unbuilt designs, and any image you would not want sitting on a third-party server. Privacy is the default here, not a paid feature.
