Fix a typo in a PDF someone sent you, in under a minute

The 60-second fix

1. Drop the PDF on the box above. It opens in the editor with the Select tool picked.
2. Find the typo. Ctrl+F opens a search bar that highlights every match, which is quicker than scrolling a 48-page report.
3. Double-click the line. A box opens over it with the text of that line.
4. Correct the word. Enter applies it; Escape backs out unchanged.
5. Click Save. You get name-edited.pdf as a new file; the original is untouched.

On a phone: tap the line, then tap Edit in the bar that appears, or tap the line twice.

We tried it on a test letter printed to PDF from Chrome in Arial: “Please recieve the attached report.” became “Please receive the attached report.” The line stayed in the file’s own Arial, at exactly the same width (184.0 points before and after), in the same place. Searching the saved file found “receive” and not “recieve”.

Why the font sometimes shifts

A PDF usually carries its fonts inside the file, but only the letters the author used. Swapping “ie” for “ei” needs no new letters, so the edit stays in the original font. Changing “30” to “14” in a line that never had a 1 or a 4 does need them, and a font cannot draw letters it does not carry.

When that happens the editor sets the line in the closest standard font, Helvetica, Times or Courier, or in a bundled Liberation font for letters such as Č, ł or Cyrillic. The status line at the bottom names the font and the missing letter before you save. Helvetica, Times and Courier have the same letter widths as Arial, Times New Roman and Courier New, so in those fonts the line keeps its length. In a font like Verdana it does not: our test line came out about 13 % narrower. Why the font changes when you edit a PDF has the full story and how to get the closest match.

When the line opens only partly

Some files store a line as several pieces, and a few store every letter as its own piece. Chrome’s print to PDF does this with some fonts: in our test invoice, “Bill to: Jane Cooper, Vienna” came out as 3 pieces, and a Times New Roman line came out letter by letter. Double-click then opens only the piece you clicked.

What to do:

• A correction of the same length works fine in a piece: fix the word inside it and the rest of the line stays aligned.
• A longer correction runs into the next piece, because pieces do not push each other along. In our test, replacing “Jane Cooper” with a longer name overlapped “, Vienna”. Edit the next piece too (shorten it or delete it with the Delete key), or drag it right with the Select tool.
• A line stored letter by letter is slow to fix piece by piece, and find and replace cannot change it either: it reports how many matches it could not change. Here a white rectangle and a new line of text is the practical fix, done honestly: the white-out guide shows how, and what stays in the file underneath.

When the typo is on a scanned page

A scan is a photo of a page. A click selects the whole picture, not a word, because there are no words in the file. Run OCR PDF to add a text layer first. That layer is invisible text placed over the picture: it makes the page searchable, but the letters you see are still the photo. To change what a reader sees on a scan, cover the word with a white rectangle and type over it, and know that the original stays in the picture.

Checking your work

1. Press Ctrl+F and search for the old spelling. 0 matches means it is gone from every page.
2. If it appears more than once, press Ctrl+H, type the correction in the Replace with box and choose Replace all. Turn on Whole words only so “teh” does not hit inside a longer word. The find and replace guide has the details.
3. Glance at each changed line. A correction in a substituted font is named on the status line; check it reads well next to its neighbours.
4. Save, open the new file in your usual viewer and search once more.

When not to fix it yourself

A typo in your own draft, your own invoice or a report before it goes out: fix it. A typo in something someone else issued is different. A signed contract, a certificate, a payslip, a bank letter or anything official should be corrected by the issuer and sent again, because a quietly altered copy can cause more trouble than the typo. If the file carries a digital signature, the editor adds your change after the signed part and tells you so, and any signature check will show the document was changed after signing. We explain the tool here, not the law; when in doubt, ask the sender.

The honest limits

• The edit applies to one line, or one piece of a line. Text does not reflow, so a much longer correction runs past the right margin rather than wrapping.
• Text inside grouped graphics (a logo, a chart, a decorated heading) cannot be retyped.
• A font that lacks your letters gets a near match, not the original. Getting the exact font back means asking the author for the source file.
