How to Choose the Right PDF Tool
With so many options available, selecting the right tool depends on your specific needs:
Prioritize Privacy
Look for tools that process files client-side (in your browser) rather than uploading to remote servers. This ensures your sensitive documents never leave your device.
Check for Watermarks
Many "free" tools add watermarks to output files, making them unsuitable for professional use. Verify that tools provide clean output without branding.
Test Browser Compatibility
Ensure the tools work on your preferred browser (Chrome, Firefox, Safari, Edge) and operating system.
Verify File Size Limits
Some tools restrict file sizes on free tiers. If you regularly work with large PDFs (100MB+), confirm the tool can handle your files.
Pro Tips for Working with PDFs
1. Optimize Images Before Conversion
If you're converting images to PDF, compress and resize them first using an Image Compressor and Image Resizer. This creates smaller, more manageable PDFs.
2. Use Consistent Naming Conventions
When merging multiple PDFs, use clear, descriptive file names: "2026-Q1-Financial-Report.pdf" is better than "report-final-v2.pdf".
3. Compress After Merging
After combining multiple PDFs, run the merged file through a compressor to eliminate redundancy and reduce overall size.
4. Keep Originals
Always maintain uncompressed, unencrypted master copies of important documents. Compression is lossy, and forgotten passwords can lock you out permanently.
5. Test Compressed Files
After compression, open the PDF and verify text readability and image quality before deleting the original.
