What Does PDF Compression Mean?

PDF compression reduces the file size of a PDF while keeping the content readable and usable.

Compression helps when you need to:

• Upload PDFs to websites with size limits
• Send documents by email
• Store files efficiently
• Share PDFs faster online

PDFHQ uses smart, AI-assisted compression to balance file size and quality.

The Three Compression Levels Explained

PDFHQ offers three simple compression options, designed for different needs.

---

🔹 Recommended Compression (Balanced)

Best choice for most users

This option provides the best balance between file size and quality.

✅ Use this if:

• You’re not sure which option to choose
• The PDF contains text and images
• You need good readability
• You’re sharing or uploading documents

📌 This is the default and recommended option for beginners.

---

🔹 Less Compression (Best Quality)

Best for important or detailed documents

This option reduces file size slightly while preserving the highest possible quality.

✅ Use this if:

• The PDF contains diagrams, drawings, or small text
• You plan to print the document
• Quality matters more than file size
• The file is already small

📌 Ideal for manuals, contracts, and technical documents.

---

🔹 Extreme Compression (Smallest File Size)

Best when size matters more than quality

This option produces the smallest possible file, but image quality may be reduced.

✅ Use this if:

• You need the smallest file size possible
• The document is mostly text
• You’re uploading to strict size limits
• Minor quality loss is acceptable

⚠️ Not recommended for documents with fine details or images.
