Complete Guide to Free PDF Tools in 2025

Last updated: January 2025 | 10 min read

Looking for free PDF tools? You're in the right place. This comprehensive guide covers everything you need to know about converting, editing, merging, and managing PDF files without expensive software like Adobe Acrobat.

Why You Need Free PDF Tools

Adobe Acrobat costs $19.99/month, Smallpdf limits you to 2 files per day, and iLovePDF uploads your private documents to their servers. There's a better way: free, private, offline PDF tools that work entirely in your browser.

1. How to Convert Images to PDF (Free)

Converting JPG, PNG, or other images to PDF is one of the most common tasks. Here's how:

1. Select your images - Choose one or multiple image files (JPG, PNG, GIF, BMP, WEBP)
2. Click Convert to PDF - The conversion happens instantly in your browser
3. Download your PDF - Get your converted file immediately

Pro tip: You can convert multiple images at once and they'll be combined into a single PDF document.

2. Merge Multiple PDFs into One File

Need to combine several PDF documents? Here's the easiest way:

• Upload 2 or more PDF files
• Arrange them in your preferred order (drag & drop)
• Click "Merge PDFs"
• Download the combined PDF

Use cases: Combining invoices, merging contracts, creating document packages, assembling reports.

3. Split PDF Pages

Extract specific pages from a PDF document:

• Upload your PDF file
• Enter page range (e.g., "1-3, 5, 7-end")
• Click "Split PDF"
• Download the extracted pages

4. Compress PDF File Size

Reduce PDF file size by up to 90% while maintaining readability:

• Low compression: Best quality, larger file
• Medium compression: Balanced quality and size (recommended)
• High compression: Smallest file, lower quality

When to compress: Email attachments, website uploads, storage optimization.

5. Sign PDF Documents Electronically

Add your signature to PDFs without printing:

1. Upload your PDF
2. Draw your signature with mouse or touchscreen
3. Position and resize the signature
4. Apply to specific pages or all pages
5. Download the signed PDF

6. Edit PDF Files (Add Text & Images)

Modify PDF content directly:

• Add text annotations
• Insert images
• Highlight important sections
• Draw on PDFs
• Edit multiple pages separately

7. Add Watermarks to PDFs

Protect your documents with custom watermarks:

• Enter your watermark text
• Adjust size, opacity, and color
• Apply to all pages
• Download watermarked PDF

8. Scan Documents to PDF
