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.
Worked example: combine a cover, report and appendix
Suppose a cover PDF has 2 pages, a report has 7 and an appendix has 4. Choose Merge PDFs and arrange the files as cover → report → appendix, using drag controls or the up/down buttons on touch and keyboard devices. Check that the operation preview expects 13 pages before confirming. That page count is a check for this example, not a guarantee about every PDF.
If the recipient only needs pages 3–5 of the original report, switch to Split / extract, select only the original report and enter 3-5 in Page range. To create ONE three-page PDF, turn OFF the initially checked Create one PDF per page option. Leaving it checked instead creates THREE separate one-page PDFs. Check the preview and the downloaded result against the original report; merged-document page numbers are not interchangeable with original-file page numbers.
- Keep the source files and select only unencrypted PDFs that the browser can read.
- Verify merge order; for extraction check the source PDF, page range and Create one PDF per page setting against the deliverable you need.
- Wait for the operation preview to confirm inputs, planned pages, output count and required credits before choosing Confirm preview & start. Open the downloaded output and check its page count and first and last pages.
- Before sharing, confirm no unrelated appendix or confidential page was included.
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.
