What a local PDF utility can do
FileNest currently supports merging multiple PDFs in a chosen order, splitting or extracting page ranges, and creating a PDF from ordered JPG or PNG images. These operations run in the browser.
They are page-structure jobs, not a replacement for a full PDF editor, OCR system or Office converter.
Why encrypted, damaged or extremely large PDFs are different
Encrypted files require permission and decryption handling, damaged files may not parse reliably, and very large PDFs can exceed browser memory. FileNest explicitly does not support encrypted PDFs and retains a failure boundary when a file cannot be handled safely in the browser.
PDF page operations and OCR are different tasks
Splitting a PDF does not turn text inside scanned pages into editable text. FileNest's separate OCR tool currently accepts clear JPG, PNG and WebP images rather than reading PDF files directly. OCR output should still be reviewed by a person.
Confirm page order before merging
Covers, body sections, appendices and attachments are easy to misorder when filenames sort unexpectedly. A reliable workflow confirms drag order and page ranges first, generates a new PDF and keeps the originals as a fallback.
- Confirm file order first.
- Recheck page ranges before extraction.
- Open the generated PDF and spot-check the first and last pages.
- Do not overwrite the source files.
