Is a PDF really riskier for applicant tracking systems?

This was a genuine concern years ago and is largely outdated. Current systems read PDFs routinely. The remaining risk is not the format but the content. A PDF that holds an image instead of text cannot be read, and that is true of any format.

Should I send both versions?

Only if the application allows more than one file and does not specify. Sending two files where one was asked for creates work for the recipient and occasionally confuses the system, which may index the wrong one.

How do I know my file has real text?

Open it and try to select a sentence with the cursor. If the text highlights, it is real text. If the selection covers the area but nothing highlights, the page is an image and nothing in it will be read.

PDF or Word: which format should you send?

This question gets a confident answer in both directions, usually with no evidence attached. The honest position is that format matters far less than construction. A well built PDF and a well built Word file both parse cleanly. A badly built one of either fails in the same way.

When PDF is the right choice

A PDF looks the same everywhere. Your spacing, your fonts, and your page breaks survive the trip. A Word file can reflow on a machine with different fonts installed, and occasionally arrives looking nothing like what you sent.

The condition is that the PDF must contain real text. A PDF exported from a word processor does. A PDF produced by scanning a printed page, or by exporting a design as a picture, does not. It is an image, and nothing inside it can be read.

You can test this in a second. Open the file and try to select a sentence with your cursor. If the text highlights, it is real. If nothing selects, no parser will ever read it.

When Word is the right choice

Some job postings ask for .docx explicitly, and some systems handle it more reliably. If a posting names a format, send that format. Ignoring an instruction on the application itself is a worse signal than any parsing risk.

Word files also have one small structural advantage. Headings, lists, and tables carry explicit markup, so a parser does not have to infer structure from visual position the way it does with PDF.

What actually breaks parsing, in either format

The failures are the same on both sides, which is the point. Tables scramble reading order. Text inside images disappears. Contact details in headers and footers can be skipped. Multiple columns interleave.

Change any of those and both formats improve. Change the extension alone and nothing does.

The old .doc format is a different matter. It is a closed binary format and cannot be read reliably. If that is what you have, open it in Word and use Save As to produce a .docx.
Never send a scanned or photographed resume. It carries no text at all.
Do not password protect the file. A protected document cannot be opened by the system that receives it.

A practical rule

If the posting names a format, use it. If it does not, send a PDF exported from your word processor and confirm you can select the text.

You can upload either format here. The analysis reads both and reports what came out, so you can see the result rather than trusting a rule of thumb.
