Trace a selected PDF page into closed DXF outlines. Choose a page from local thumbnails, crop, adjust threshold and cleanup, then inspect the processed mask and generated DXF. Raster tracing, not CAD reconstruction.
No file selected.
One unencrypted PDF up to 50 MiB / 2,000 pages. Only the selected page is rendered for tracing, at most 2048 px per side / 4 megapixels. No OCR or vector extraction. Page annotations/forms are excluded.

Thumbnail strip shows up to six pages around the selection. Page previews are rendered locally. Links, attachments and scripts are not opened.
The traced DXF outlines will appear here.
No DXF generated.
The preview reparses the actual DXF. Thick lines produce two boundaries, not a single centerline. Holes become separate closed polylines. Anti-aliasing, threshold, downsampling and simplification can change dimensions and topology.
Output: AC1015 ASCII DXF, closed LWPOLYLINE outlines on layer 0. PDF pages render on white before tracing. No OCR, centerline extraction, CAD layer/dimension recovery, original CAD scale recovery, background understanding, path repair or cutter compensation. Complex/noisy images may exceed bounded tracing limits. Use clean artwork, inspect holes/gaps/duplicate edges and verify scale in CAD/CAM before any fabrication. Keep the source PDF.
Your PDF is never uploaded to any server; PDF rendering, outline tracing, DXF creation and previews run locally in your browser. Actual page previews and clear scale/trace reports help you inspect the result before saving.
No. The selected PDF page is rasterized and its foreground boundaries are traced. This also works on vector PDFs, but it does not extract their vector paths. Thick lines produce multiple boundaries, text becomes traced outlines, and original layers, dimensions and drawing scale are not recovered.
The explicit scale is DXF units per displayed PDF page point, with 72 points per inch. The default 25.4/72 approximates nominal printed page size in millimetres. It is not a recovery of the original CAD drawing scale. Rotation and the displayed page box are applied; the crop lower-left is the output origin. The unit label alone does not rescale coordinates.
Only the selected page is rendered, with page rotation and its displayed box applied. Annotations/forms are excluded. Links, scripts and attachments are not opened. Password-protected PDFs are unsupported; use an unencrypted document.
One PDF up to 50 MiB and 2,000 pages; displayed page sides at most 16,384 points. Rasterization is capped at 2048 px per side and 4 megapixels. Shared tracing limits are 200,000 boundary edges, 100,000 output vertices and 10,000 outlines. Complex documents may require a simpler source or lower tracing resolution.
Inspect it in CAD/CAM first. Thresholding, downsampling and simplification can change dimensions, holes and topology. There is no centerline extraction, gap repair, duplicate-edge cleanup or cutter compensation. Keep the original PDF.
