Dealing with PDF Files in Daily Work
PDF is the standard format for business agreements, financial statements, and resumes. However, editing them can be annoying:
- How to merge multiple scattered contracts into one file?
- How to save just a few pages from a 100-page report to send to a client?
The Risks of Online PDF Uploaders
Most free PDF sites require you to upload your files. PDF files often contain bank statements, tax records, signatures, and ID copies. Uploading them means losing control of your data, exposing you to privacy leaks.
Client-side PDF Processing
Modern browsers are fast enough to parse PDFs locally. We use the standard library pdf-lib to:
1. Load PDF bytes directly in your local browser tab memory.
2. Extract, copy, and merge PDF tree nodes.
3. Package and trigger the download instantly without server network transits.
