Step-by-Step Walkthrough
Open AyFetch PDF Tools
Navigate to the AyFetch PDF Tools page. Choose either 'Merge PDFs' to combine files or 'Split PDF' to extract pages.

Process and Download
Click 'Merge PDFs' or 'Split PDF'. The tool processes your files instantly in your browser. Click 'Download' to save the resulting PDF.
Why Process PDFs in the Browser?
Many online PDF tools require you to upload sensitive documents to remote servers, creating privacy risks for confidential business reports, legal documents, and personal files.
AyFetch PDF Tools processes everything entirely within your browser memory. Your files are never transmitted over the internet.
Common Use Cases for PDF Merging and Splitting
Merging PDFs is useful when you need to combine a cover letter and resume, assemble reports, consolidate bank statements, or package documentation.
Splitting PDFs is ideal when you want to extract a single contract page, separate a scanned document, or share only a specific chapter.
Common Questions & Troubleshooting
Is there a maximum file size for merging PDFs?
Since processing happens in your browser, the limit depends on your device RAM. Most modern computers can handle merges totalling 200MB+ without issues.
Are my PDF files private when using AyFetch PDF Tools?
Absolutely. AyFetch PDF Tools is 100% client-side. Your files are processed entirely in your browser and are never uploaded to any server.
Can I merge password-protected PDFs?
You will need to remove the password protection from encrypted PDFs before merging. AyFetch currently supports only unencrypted PDF files.
