In short
To change text in a PDF, open the file, tap the line or paragraph, type the new text and save. The old words are removed from the page and the new ones are written in the same place, size and colour, then every word is checked. Your file is never uploaded.
A PDF is made to look the same everywhere, not to be edited. Its text is a list of drawing instructions: put these letters, in this font, at this point. That is why a small mistake, a wrong date in an offer letter, an old phone number on a resume or a typo in a certificate request, usually means going back to the Word file. When that file is lost, most people end up covering the mistake with a white box and typing over it. The old text is still in the file underneath, and anyone who copies the page, searches it or runs it through an ATS will still find it.
This editor works on those drawing instructions directly. It reads every page twice: once with pdf.js, the engine inside Firefox, to see what each line says and where it is, and once with pdf-lib, to find the exact instructions in the page that draw it. When you change a line, those instructions are removed from the page, and your new text is written in their place with the same size, colour and weight. Arabic is written with an embedded Arabic font, with joined letters and right-to-left order, so it copies back as the same words.
After saving, the editor opens the new file the way any reader would and compares the words of every page with what they should be: the original words, minus the text you changed, plus your new text. If anything differs, it tells you which words, instead of reporting a silent success.
How to edit the text of a PDF
Step 1: Open the PDF
Drop a PDF of up to 50 MB and 30 pages. Each page appears with a frame around every line and paragraph that has real text.
Step 2: Tap the text to change
Type the new text, or delete it. Paragraphs wrap to their original width. Keep “shrink if it does not fit” on so a longer line keeps its place.
Step 3: Check the changes
Changed blocks turn green. You can change several lines on several pages, and undo any of them before saving.
Step 4: Save the edited PDF
The file is written, checked word by word, and downloaded. Every page you did not touch stays exactly as it was.
Zero-Server
Editing a PDF without uploading it
The file is read and written inside a Web Worker in this browser tab. The worker starts when you choose a PDF and closes a minute after its last task. No server receives the file, the text you type or the result. The Arabic font, when it is needed, is downloaded from careerpdf.com itself and is the same for every visitor.
Nothing is kept after you leave the page: there is no account, no history and no cookie. The privacy meter at the top of the page counts requests to other websites, and it stays at zero while you edit.
When people edit text in a PDF
- Correcting a date, an amount or a name in a letter or a certificate request you only have as a PDF.
- Updating the phone number, email or job title on an old resume without rebuilding it.
- Removing a line that should not be sent, such as an internal note or a private detail.
- Fixing a typo in a form or a cover letter just before uploading it to a job portal.
Frequently asked questions
Is the old text really removed?
Yes. The instructions that drew the old words are deleted from the page, so they cannot be selected, copied or found by search, and an ATS reads only your new text. Nothing is covered with a white box.
Why are some lines grey and locked?
A line is locked when changing it could damage the page. Examples are the invisible text layer of a scan, text drawn inside a reusable block, text written together with its neighbour, and fonts that do not say how wide their letters are. Tap a locked line to see the reason.
Will the new text use the same font?
It uses the same size, colour and weight, and the closest standard font: Helvetica for sans-serif text and Times for serif text. Arabic uses the embedded Vazirmatn or Markazi Text. A rare decorative font will look slightly different, so check names and headings.
Can I edit a scanned PDF?
No. A scan is a picture of a page, with no text to edit. Turn it into text with the OCR tool first, then rebuild the document, for example in the resume builder.
What if the new text is longer than the old one?
With shrinking on, the text is made smaller, down to 70% of its size, until it fits the original width. Paragraphs wrap to the same width. If it still does not fit, the editor warns you that it may overlap the next line.
Are forms, images and links kept?
Yes. Only the text operators you edited change. Images, drawings, links, form fields and the rest of the page stay as they were, and pages you did not touch are not changed.
Which browsers does it work in?
Current versions of Chrome, Edge, Firefox, Safari and Samsung Internet on desktop, Android and iPhone. JavaScript must be enabled, because the file is edited on your device.
