TL;DR

Use iLovePDF or Smallpdf for everyday Excel/Word/JPG → PDF conversions, Adobe Acrobat for tricky formatting and OCR, PDF24 desktop for sensitive files.

When You Need an AI-Powered PDF Tool

PDFs are still the universal document format for contracts, invoices, reports, and CVs. The challenge is getting your file into PDF — or out of one — without losing formatting. Modern AI-powered PDF tools handle conversion, OCR, compression, and editing in your browser with no install. This tutorial walks through the most common conversions step by step.

Step 1: Convert Excel to PDF

Go to iLovePDF.com → Excel to PDF. Drag your .xlsx file into the upload box. Choose 'Fit to one page' if your sheet is wide, then click Convert. Download the PDF in 5–10 seconds. Smallpdf and PDF24 work the same way — pick whichever loads fastest in your region.

Step 2: Convert Word to PDF (Preserving Formatting)

For Word documents with complex formatting (tables, headers, footnotes), Smallpdf and Adobe Acrobat preserve layout best. Upload your .docx, click Convert, and download. If formatting breaks, try Adobe Acrobat's free online converter — it handles edge cases best.

Step 3: Convert JPG, PNG, or Scanned Photos to PDF

iLovePDF's JPG to PDF tool lets you upload multiple images and combine them into a single PDF — perfect for sending receipts or photo IDs. Drag images in the order you want them, choose page size (A4, Letter), and click Convert.

Step 4: Run OCR on a Scanned PDF

If your PDF is a scanned image (no selectable text), use Smallpdf's or Adobe's OCR feature. Upload the file, choose the language, and the AI extracts the text into a searchable, copyable PDF. CleverPDF offers similar functionality with no daily limits.

Step 5: Merge, Split & Compress

To merge: upload multiple PDFs in order, click Merge. To split: upload a PDF and pick the page ranges to extract. To compress: upload and choose 'recommended' compression — usually shrinks files 60–80% with no visible quality loss. PDF24 is fully free with no daily caps for these tools.

Privacy Tip: When to Use Desktop Instead of Online

Online converters are fine for everyday docs, but for sensitive contracts or legal files, use a desktop app like PDF24's free Windows tool or Adobe Acrobat. Files never leave your computer, eliminating any privacy risk.
