Resume PDF or Word: Which Format Beats the ATS?

"Resume PDF or Word" is the question that fills every UK jobseeker forum, and the most common answer is wrong. People still repeat that Word sails through applicant tracking software more easily. That was true in 2015, not in 2026. Here is what an ATS (Applicant Tracking System) actually reads, and the format that gives you the best odds whether you apply through a corporate portal or via reed.co.uk.

The "Word is safer" myth is dead

For years the standard advice was to send a .doc because old ATS parsers choked on PDFs. Modern engines (Taleo, Workday, iCIMS) now pull text from a cleanly exported PDF without trouble. The real risk is no longer the extension: it is an "image" PDF from a scan or a flattened Canva export, which the machine cannot read. A PDF generated from a word processor is still a text document, so it parses perfectly.

What the ATS really reads in a file

An ATS does not "see" your layout: it extracts a stream of text, then sorts it into fields (experience, education, skills). Three things break that extraction, regardless of format:

• Multiple columns: the parser reads left to right and scrambles the blocks.
• Text inside an image or a floating text box: invisible to the parser.
• Nested tables and headers or footers holding key details.

A single-column PDF with selectable text beats a Word file stuffed with tables. Format matters less than structure.

When Word is still the right call

One case still justifies .docx: when the advert or the recruiter explicitly asks for it, often because a consultant wants to annotate or anonymise your CV before sending it to the client. The UK's National Careers Service accepts both, and government guidance on applying for jobs via gov.uk makes clear that an editable file circulates more easily through agencies. Simple rule: if they ask for Word, send Word.

Fonts, columns, photo: the real parsing killers

Format rejects no one, formatting does. Stick to a standard font (Arial, Calibri, Georgia) at 10 to 12 point: decorative fonts turn into garbage characters on extraction. In the UK, do not add a photo. British hiring norms discourage it to reduce bias risk, and most recruiters expect a text-only header. For length, two pages is the accepted standard, which matches the labour-market context tracked by the Office for National Statistics where competition for roles keeps recruiters skimming fast.

The rule that settles the debate

1. No instruction in the advert: send a PDF exported from a text editor (not a scan, not a flattened image).
2. Word requested: provide a clean .docx, single column, no tables.
3. Either way: test it by copy-pasting your CV into a plain-text editor. If the text comes out in order and complete, the ATS will read it too.

In short

PDF or Word is no longer the right question. A text-based PDF, single column, standard font: that is the winning trio. Save Word for adverts that demand it, and always check that your text copies out cleanly. Format never eliminates you. A chatty layout will.
