Tools
Step 1 of 5
From Any Application
Most applications can export to PDF. In any program, go to File → Print → Select 'Print to PDF' or 'Save as PDF' as your printer. This works universally across platforms.
Step 2 of 5
From Word/Google Docs
In Microsoft Word: File → Save As → Choose PDF format. In Google Docs: File → Download → PDF Document. Both produce high-quality PDFs with formatting preserved.
Step 3 of 5
Merge Multiple PDFs
Use free tools like PDF Merge (online) or Adobe Acrobat. On Mac, use Preview: Open the first PDF, enable thumbnails, drag additional PDFs into the sidebar, and save.
Step 4 of 5
Add Signatures
Use Adobe Reader's Fill & Sign feature, or on Mac, use Preview's Annotate → Signature. Create your signature once with your trackpad or camera, then reuse it.
Step 5 of 5
Optimize File Size
Large PDFs can be reduced using online compressors or Adobe's Reduce File Size option. For print quality, keep at 300 DPI. For email/web, 150 DPI is usually sufficient.
Pro Tip
For scanned documents, use OCR (Optical Character Recognition) to make the text searchable.
