Guides

Complete workflows, start to finish.

Four guides that cover nearly every document you'll meet. For 30-second answers, see the mini tutorials or the FAQ.

Use the PDF power tools

Transform pages or document security without sending the file to a server.

1
Open Tools and choose the focused workflow: Merge, Split, Organize, Rotate, Page Numbers, Protect, or Unlock.
2
Choose PDF files and review page counts, thumbnails, encryption status, and operation settings.
3
For protected inputs, enter an authorized password in the password field shown for that file.
4
Set file order, page ranges, page selections, numbering, or permission options as required by the tool.
5
Generate the result. Processing runs in a browser worker and the output downloads only after validation succeeds.
6
Reopen important output to confirm page order and security before sharing or submitting it.

The bread-and-butter workflow: a dense official form with small boxes and strict layout.

1
Upload the PDF from the editor's start screen — the AI scan runs automatically when the document opens.
2
Review the detected fields. Fields that came with the form (even locked, completed ones) arrive pre-filled with their existing values.
3
Click any field to fill it. The fill bar keeps focus so you can Tab through the document top to bottom.
4
Toggle checkboxes with a single click; use the cross tool for boxes that expect an X instead of a checkmark.
5
Zoom in for tight rows and use the numeric position controls to nudge a field into exact alignment.
6
Export when done, then open the file once in a PDF viewer to confirm every value landed where it should.

Add a real drawn signature and produce a submission-ready file.

1
Select the signature tool and click where the signature belongs — a drawing pad opens.
2
Draw with a mouse, finger, or stylus. Redraw as many times as you like before accepting.
3
Resize the placed signature to fit the line; the stroke stays sharp at any size.
4
Add the date beside it with a text or number field using an export-safe font.
5
Export to download, or print directly. Exports are vector-based, so text remains selectable.

Both tools are text-aware: they follow the words underneath instead of guessing.

1
Pick the highlight tool and drag across the passage — one marker stroke snaps to each covered line, blending like a real highlighter.
2
Click a single line with the highlight tool to mark the whole visible line in one go.
3
Pick the erase tool and drag over unwanted text — the cover box hugs exactly what you covered.
4
Match the erase color to the page background with the swatches if the paper isn't pure white.
5
Adjust any placed highlight or erase box afterwards: move it, resize it, or delete it like any other element.
6
Remember: erasing covers content in the standard export. For truly sensitive data, redact at the source.

No detector is perfect. Here's the fast path from a noisy scan to a tidy form.

1
Run Rescan first — it merges newly found fields without duplicating the ones you already have.
2
Missing a field? Add it manually with the text, number, check, or signature tools; manual fields behave exactly like scanned ones.
3
Got a duplicate or misplaced box? Select it and delete or drag it — AI fields are never locked.
4
If the scan is mostly noise on an unusual document, use “Clear AI fields” and place fields manually — your own work is kept.
5
Scanned-image PDFs (photos of paper) have no machine-readable text; manual tools are the right approach there.
