How to Convert Autocad To PDF
AutoCAD drawings (.dwg and .dxf files) contain precise 2D and 3D designs used in architecture, engineering, and manufacturing. Converting them to PDF makes drawings viewable by anyone — clients, contractors, and regulatory reviewers — without AutoCAD software. The conversion must preserve line weights, layer visibility, text accuracy, and dimensional precision at scale.

Open the drawing in AutoCAD
Open your .dwg or .dxf file in AutoCAD. Switch to the layout tab (paper space) you want to export — model space exports the entire drawing, while layout tabs export formatted sheets with title blocks and viewports.
Configure plot settings
Use File → Plot (Ctrl+P). Select 'DWG to PDF.pc3' as the plotter. Choose a paper size matching your sheet (ARCH D, ISO A1, ANSI D). Set plot scale — 'Fit to Paper' for review copies, or exact scale (1:100, 1/4" = 1') for construction documents.
Set line weight and color handling
Choose a plot style table (.ctb or .stb): 'monochrome.ctb' converts all colors to black lines (preferred for construction documents), or 'acad.ctb' preserves layer colors. Enable 'Plot with lineweights' to render different line thicknesses.
Include or exclude layers
Freeze or turn off layers you don't want in the PDF before plotting. Common layers to hide: construction lines, reference images, internal notes. Each visible layer's content will appear in the PDF.
Export to PDF
Click 'OK' to generate the PDF. For multi-sheet drawings, use 'Publish' (File → Publish) to export all layout tabs as a single multi-page PDF or individual PDF files per sheet.
Pro Tips
- 💡 Use the 'DWG to PDF.pc3' driver for best results — it's optimized for AutoCAD drawings and produces smaller, sharper PDFs than generic PDF printers.
- 💡 For regulatory submittals, export at exact scale with a title block that includes the scale factor. Reviewers need to measure drawings accurately with a scale ruler on the printed PDF.
- 💡 Enable 'Include layer information' in the PDF export options to create PDF layers (OCGs) that mirror your AutoCAD layers — viewers can toggle layer visibility in the PDF.
- 💡 Export large format drawings (ARCH E, ISO A0) as PDF and let the recipient scale to fit their printer — PDF viewers handle this better than sending oversized paper format files.

How to Convert Scanned PDF to Text
Scanned PDFs are essentially images — you can't select or search the text. OCR (Optical Character Recognition) technology converts these image-based PDFs into searchable, editable text. SublimePDF's OCR tool handles this conversion right in your browser.
How to Convert PDF To Grayscale
Printing color PDFs on black-and-white printers often produces muddy, hard-to-read output because the printer's automatic color conversion isn't optimized for clarity. Pre-converting your PDF to grayscale ensures consistent, clean results on any mono printer and can dramatically reduce printing costs for large jobs. SublimePDF converts all colors—in text, images, and vector graphics—to properly weighted grayscale.
How to Convert Emails To PDF
Archiving emails as PDFs preserves the complete message—headers, body, formatting, and attachments—in a universal format that doesn't require any email client to view. Legal compliance, business record-keeping, and personal archiving all benefit from having emails in a searchable, printable, tamper-evident PDF format. SublimePDF converts email files from Outlook, Gmail, and other clients into clean, well-formatted PDFs.
