01What it does

Edit the document you opened, not a copy of it.

Most tools export a new PDF that merely resembles the old one. Here the fonts, spacing, links, bookmarks and form fields are all still in the file afterwards.

01Edit real text

Retype the page. Keep the file.

Click into any sentence and type. The change lands in the original file, in the original font, and everything around it stays exactly where it was.

  • Swap, move, resize or delete embedded images
  • Highlight, comment, shapes, links and attachments
  • Compare two revisions and see exactly what changed

02Redaction that removes the text

A black rectangle drawn over a name is not redaction. The text is still in the file and copies straight out. LumenPDF deletes the content and the layer beneath it, then sanitizes the file.

Hidden authorship and revision metadata stripped too

03Pages by dragging

Page work is the most common reason a PDF gets sent back. Here it is all direct manipulation.

No dialog asking for a page range

04Fill it, or build it

Complete the form somebody sent you, or add real fields to a flat document.

Sign with a certificate where identity matters

05Scans become text

A photographed contract is an image of words. OCR makes it text, then anything.

A fully editable .docx or .xlsx in one click

06Ask the document

It reads all 42 pages, not the one you are on, and the answer is the start of an edit.

Answers cite the passage they came from

02LumenAgent in LumenPDF

It does the whole job, and stops to ask.

It reads the file, pulls in documents from your library, finds every target, then waits for you before it removes anything. Declining takes a genuinely different route.

Understand
Read the structure, the pages and the text that matter
Locate
Find every target: occurrences, fields and page positions
Edit

On Lumen Ultra, re-read the document to prove nothing was missed

Permanently remove 23 items from the file?

Redaction deletes the text and the layer under it, then sanitizes the document. Everything up to here only read the file.

03The full toolkit

Everything LumenPDF does, and all of it free.

No page limits, no watermark on the way out, no upsell in the middle of a job.

Edit & markup

Change the real page.

  • Real text editing, fonts and layout preserved
  • Swap, move, resize or delete images
  • Highlight, comment, shapes, links, attachments
  • Compare two revisions

Pages

Direct manipulation, not dialog boxes.

  • Add, delete, reorder, rotate, extract by drag
  • Merge many into one, or split one into several
  • Crop and resize across a selection
  • Compress for email, still readable
  • Booklets and N-up print layouts

Forms & signatures

Fill one, or build one.

  • Type into fields, tick boxes, set dates
  • Create text, checkbox, date and initial fields
  • Draw, place, or sign with a certificate

Redact & protect

Removal, not concealment.

  • Secure redaction deletes the text and its layer
  • Strips hidden authorship and revisions
  • Passwords and recipient permissions
  • Watermarks, page numbers and headers

Read & convert

Make it text, then make it anything.

  • OCR for scans and photos
  • A fully editable .docx or .xlsx in one click
  • Clean text and structured tables out
  • An accessible copy: language, tags and image descriptions

The agent

Instructions instead of clicks.

  • Summarize 90 pages into dates and obligations
  • Extract every figure into a workbook
  • Answers cite the passage they came from
  • “Remove every email address”, as real redactions

04Works with the rest

The PDF is not on its own.

“Pull these terms into a spreadsheet” is one instruction, not an export and a re-import.

  1. Starts here

    A 42-page scan

    Flat images of words. OCR makes it text, and everything else follows from that.

  2. Hands off

    Figures to LumenSheets

    The payment table is built by the spreadsheet’s own agent, with its formulas and checks.

  3. Hands off

    A summary to LumenDocs

    The key dates and obligations, written up as a document you can send.

  4. Hands off

    A deck to LumenSlides

    The same facts as a short deck when the answer has to be presented.

05Questions

Common questions

Will editing change the original fonts and layout?

No. You edit the real text in place, so original fonts, sizes, spacing and layout are preserved.

Is the redaction actually secure?

Yes. The text and its underlying layer are permanently removed and the file is sanitized. It can’t be copied out or recovered.

Does the agent change my file without asking?

No. Reading runs freely, but anything that removes content, writes to disk or creates a document pauses and asks first.

Can I convert a PDF to Word or Excel?

Yes. Export any PDF to a fully editable .docx or .xlsx in one click.

Does it handle scanned PDFs?

Yes. Built-in OCR turns scans and photos into searchable, editable text, and on Plus and above it can escalate difficult pages to AI vision.
