Convertio offers advanced OCR (optical character recognition) for CAD—something rare in free tools. The free plan allows up to 10 conversions per day (files under 10MB).
Why it beats Scan2CAD in one aspect: Convertio’s CAD conversion actually recognizes text and converts it to editable text entities (not just lines). Scan2CAD’s OCR is an add-on module that costs extra.
Pros: Recognizes dashed lines, hatches, and text.
Cons: Requires daily limits; no batch processing free.
Best for: Students and freelancers converting PDF drawings with notes and dimensions.

Best for: Users who need to edit the drawing immediately after conversion.
LibreCAD is a free, open-source 2D CAD application. It does not have powerful raster-to-vector conversion capabilities built-in, but it handles vector data natively.
While you typically still need to convert your image to a vector format (like SVG) using Inkscape first, LibreCAD is the destination where you fix the drawing. It is the best free environment to clean up the "messy" lines that free converters often create.

This is a legacy tool that still works well on Windows 10/11. The free version converts only the first page of a PDF and adds a small watermark. However, for single small drawings, it’s effective.

Best for: Mechanical engineers dealing with multi-sheet PDFs who don't mind a little extra work. Pros: No installation
