# 6 Concise Strategies for Email-Friendly PDFs
Emailing PDFs often frustrates—large files bounce, download slowly, or fail on mobile. Optimize them with these tactics for smooth delivery.

1. **Compress Efficiently**: Use free online tools to shrink PDFs under 25MB(e.g., Kyojoy Tech’s PDF Compressor) . Choose “standard” for text, “high” for images, and batch-compress when needed.

2. **Split/Extract Pages**: For large docs, split by page range or extract only relevant sections(search “free PDF splitter online”) or Kyojoy’s split tool. Name files clearly (e.g., “Report_Budget.pdf”).

3. **Convert to Lighter Formats**: Turn non-editable PDFs into JPG, PNG, or TXT to cut size—note this removes editability.

4. **Optimize Images & Bloat**: Compress images to 72-150 DPI (RGB format) and remove metadata, unused fonts, or old annotations.

5. **Mobile-Optimize**: Ensure ≥12pt text, resize wide elements, and test for mobile compatibility.

6. **Use Cloud Links for Large Files**: Share PDFs over 50MB via Google Drive, Dropbox, or WeTransfer (free up to 2GB, no recipient account required).

# # Pre-Send Checklist
✅ File size ≤25MB (or use a cloud link)
✅ Images compressed to 72-150 DPI
✅ Mobile-friendly and clear file name

These strategies work fast with free tools, no technical skills needed. Start with compression and adjust as required. Need tool tips? Just ask!
