How to edit PDF text without converting to Word

Open the PDF in the editor, click a line and correct it. Press “Check result”, then “Apply changes”, and open the downloaded file: the line's font and the form fields may change.

If a PDF has a wrong date, name, or amount, you don't need to turn the whole document into a Word file. Open the Edit PDF tool: it replaces existing text right on the page, and the old line is removed from the file rather than hidden under an overlay.

The editor carries a “Beta” badge, so this guide covers not only the steps but also what to check in the finished file: the line's font, neighboring text, form fields, and any digital signature.

Check whether your PDF can be edited directly

Try selecting a few words in any PDF viewer. If a line can be selected and copied, the page has a text layer and you can edit it. Keep the original file: you will need it to compare the result and to go back to the original wording.

If the page is a scan, the editor tells you so: “This page is a scan: it has no text to change.” The “Recognise text (OCR)” button adds an invisible layer for searching and copying, but it does not change the printed letters of the scan. A visible correction on a scan is made with new text placed on top of the page; see the article on editing a scan after OCR. To recognize a whole document, you can also use the separate OCR PDF tool.

How the editor splits text into pieces

The unit of editing is a line. Clicking text opens a panel where the “Replacement text” field already holds the entire line, not a single word. Table cells, columns, and fragments in a different style usually open as separate pieces.

If the correction spans several connected lines, press “Edit the whole paragraph” in that panel; the number of lines is shown in brackets. The button works only while you haven't typed anything; otherwise the editor asks you to apply or cancel your change first. Rewriting the whole paragraph is handy when the new text is longer than the old one and has to wrap into lines again.

Don't confuse replacement with the “Text” tool on the toolbar (tooltip “Add text”). That tool creates a new label on top of the page, while the old line underneath stays in the file: a search will find it and a recipient can copy it. To fix a mistake, use replacement.

Step by step: replace a line

1. Upload the PDF on the tool page and wait for the “PDF editor” to open. 2. Go to the right page and click the line with the mistake. 3. In the “Replacement text” field, correct only the wrong fragment. Anything you erase from the field disappears from the page. 4. Check the settings under the field. In the “If the text does not fit” list, a new edit starts with “Move neighboring text”; the other options are “Widen the box without moving neighbors”, “Shrink the text”, and “Change nothing and warn”. The “Preserve source font” and “Preserve original background” checkboxes are on; leave them on. 5. Press “Apply text”. “Cancel edit” closes the panel without changes, and “Delete text” removes the line from the page. 6. Press “Check result”. This is an exact preview: the server builds the page the same way as in the final file. Until the check is done, the “Apply changes” button stays unavailable, and after every new edit you need to check again. 7. The “Output file name” field defaults to the original name ending in “-edited.pdf”; type your own name if you like. Press “Apply changes” and download the PDF that appears below.

Example: correct an invoice amount

Suppose a draft invoice says “Total: $12,500” but the agreed amount is $12,800. Click the line: the field shows the whole line. Change the “5” to an “8” and make sure the comma, the colon, and the dollar sign are still in place.

Even when you change one digit, the whole line is redrawn. An embedded font often contains only the characters that already appear in the document. If it lacks even one character you need, such as the digit 8, the entire line is set in a fallback font. So look not just at the corrected digit but at whether the font of the whole line has changed: under the preview you will see a “Font substituted” note with the font names and the reason.

The editor does not recalculate related values the way a spreadsheet does. Check the line items, the tax, and any amount written in words, and fix each of them with a separate replacement.

If the font did change

A fallback font can be wider or narrower than the original, so the line may grow and touch its neighbors. Don't shrink the type until it becomes hard to read: shorten the wording instead, or undo the edit with the “Undo” button (Ctrl+Z, or ⌘Z on a Mac) and try another option. Why this happens and how to choose a replacement is covered in the article on font changes after editing a PDF.

Forms and signed documents

If the PDF has fillable fields, a “Keep form fields interactive” checkbox appears above the page. It is off by default: after “Apply changes” the fields are flattened into the page and the form can no longer be filled in. If other people still need to fill in the document, turn the checkbox on before exporting.

Apply an electronic signature to the corrected file. Any change to the content invalidates an existing digital signature, so a signed document has to be signed again after editing. For signing without a printer, see the article on signing a PDF without printing or scanning.

Check the downloaded file

The preview is exact, but what you send is the downloaded file, so open that file rather than the tab with the original.

• Zoom in on the corrected area, then look at the whole page.
• Search for the new text in your viewer: it should be found, and the old version should not.
• Check the neighboring lines. If the preview showed a “Neighboring text moved” note, make sure nothing overlaps table borders or captions under fields.
• If the document had a form, try typing a value into any field.

Common mistakes and how to spot them

• A search still finds the old text. The “Text” tool was used instead of replacement. Delete the label and replace the line itself.
• The message “The text box overlaps neighboring text”. The new line is longer than the old one. Pick another option in the “If the text does not fit” list or shorten the wording.
• The message “The text does not fit”. Enlarge the box with the “Width (%)” and “Height (%)” fields or choose “Shrink the text”.
• The end of the line is gone. It was accidentally erased from the “Replacement text” field; open the line again and retype it.
• The form can no longer be filled in. The “Keep form fields interactive” checkbox was off. Open the original file, repeat the edit, and turn the checkbox on before exporting.
