How to use the online PDF editor
- 1Press Choose PDF. If it has fillable form fields, they are listed under Form fields in this PDF.
- 2Use Add text, Add date, Check mark, Cross, Whiteout or Signature to add an item to the page you are viewing; type its text in the Text box.
- 3Drag the item into place, or select it and use the arrow keys or the X and Y fields. Change Font, Size and Color as needed.
- 4Fill any form fields, decide whether to Flatten form fields, then press Download PDF.
Adding text and fields
Add text places a text box in the middle of the page and puts the cursor in the Text box, where Enter starts a new line. Choose Sans (Helvetica), Serif (Times) or Mono (Courier), a size in points and black, blue or red; your last choice is remembered for the next box. Add date inserts today's date in the format picked next to it, such as 2026-09-30 or 30 September 2026, as ordinary text you can change.
Check mark and Cross add marks for tick boxes on printed forms, and Signature opens the signature maker (draw, type or upload). For signing alone, sign a PDF has the same tools with signing first.
Filling existing PDF forms
If the PDF has interactive form fields (text fields, checkboxes, drop-down lists and radio buttons), they are read with their names and current values and shown as a form below the page. Fill them in there; the values are written into the real fields, so the PDF stays fillable unless you flatten it. Read-only fields are marked and can't be changed.
Forms made with Adobe LiveCycle (XFA) also contain a second, hidden form. It is removed on saving so that every viewer shows your values. PDFs without fields, such as scanned forms, are filled by placing text and check marks on the page instead.
Positioning and sizing
Drag any item with a mouse or finger. With the keyboard, Tab to an item, then use the arrow keys (1 point per press, 10 with Shift), plus and minus to resize, and Delete to remove it. The X, Y, Width and Height fields set exact positions in points from the top-left corner (72 points = 1 inch = 25.4 mm), which helps line text up with printed boxes.
Copy to pages or Copy to all pages repeats the selected item, for example a reference number in the same corner of every page. Added items lists everything with its page number.
What this editor can't change
PDFs store text as positioned characters in a font that is often only partly embedded, so changing existing words reliably needs the original document. This editor doesn't edit, delete or reflow existing text or images. You can cover something with Whiteout (a white box) and type over it, but the original text is still in the file underneath and can be found by search or copied, so whiteout is not a way to hide confidential information.
To change the wording of a document, edit the original Word or Google Docs file and convert it again with Word to PDF. To fix page order or orientation, use merge PDF or rotate PDF.
Saving and flattening
Everything you add is drawn into the page content when you press Download PDF, so it looks the same in every viewer and prints exactly as placed, and it can't be moved again in another program. Flatten form fields does the same for the form: the values become plain page content that can't be edited later. Leave it unticked if someone else still needs to fill in the form.
Your original file is not changed; the download is a new file ending in -edited.pdf.
