PDF or DOCX? Which file format is really better for applications?

Both formats are parsed by current applicant tracking systems. What actually decides the matter is different: layout fidelity, further processing inside the company and the requirement stated in the job ad.

Few questions come up as often in application forums: PDF or Word? The short answer – PDF is the standard in Germany, DOCX is the exception with good reasons. The longer answer explains why, and where the format choice really goes wrong in practice.

One point upfront: the format is rarely the reason for a rejection. Modern systems extract text reliably from both file types. Problems almost always come from how the file was created – not from the extension.

What the difference means technically

A DOCX file is an editable text document. Content, styles and layout are stored separately, and the way it looks depends on the program and fonts installed on the recipient's machine.

A PDF is a fixed output: page breaks, fonts and spacing are embedded and look identical everywhere. A normally exported PDF still contains real, searchable text – something that is often confused. Only a scanned PDF or one exported as an image is empty from a system's point of view.

PDF: pros and cons

PDF is the expected format for application documents in Germany – almost always for email applications, and usually in application portals too.

Pros

The layout stays exactly as you created it – on every device.
The content cannot be changed by accident.
Several documents can be merged into one file.
It looks professional and matches German convention.

Cons

Incorrectly created PDFs (scan, screenshot, „save as image“) contain no readable text.
Very old portal software sometimes parses complex PDF structures poorly.
Recruiters cannot add notes inside the document.

DOCX: pros and cons

DOCX makes sense when it is explicitly requested – for example by staffing agencies that anonymise or extend your profile before forwarding it to their client.

Pros

Parsed without trouble by any system, provided it is single-column.
Recruitment agencies can adapt profiles directly.
Small file size, easy further processing.

Cons

The layout shifts if fonts or program versions differ.
Comments, tracked changes and metadata can be sent by accident.
The recipient can alter the content.

What ATS actually read

Common systems handle PDF and DOCX equally well. The real sources of error lie elsewhere: multi-column layouts, tables, text boxes, contact details in the header, text inside graphics. A two-column DOCX is far more problematic for a parser than a cleanly exported single-column PDF.

A simple test helps: open your file, select all text with Ctrl+A and paste it into an empty text editor. If everything appears in a sensible order, the system will cope too. If details are missing or lines are interleaved, the layout is the problem, not the format.

Typical mistakes when choosing a format

The most common mistake is „print the PDF and scan it“. The result is an image without text. Exports from graphics programs that convert fonts into outlines are similarly problematic.

Second classic: the ad asks for Word and you send a PDF – or the other way round. If a format is named explicitly, deliver it. Third mistake: several separate files named „Document1.pdf“ or „Scan_0007.pdf“. Use a scheme such as „CV_Lastname_Role.pdf“ instead.

And finally file size: many portals limit attachments to 2–5 MB. A PDF with a high-resolution photo and scanned references exceeds that quickly. Reduce image resolution rather than leaving pages out.

Recommendation for practice

As a default, send a PDF exported directly from Word, Google Docs or Pages – single-column, with a standard font and contact details in the body text. Always keep the editable original so you can adapt the CV per role quickly.

If the ad or an agency asks for Word, send DOCX – and check beforehand that no comments, tracked changes or foreign metadata remain. The same principle applies to cover letters and references: PDF, sensibly named and in a logical order.

The short version in eight rules

Default: PDF, exported directly from the original document.
DOCX only when it is explicitly requested.
Never scan or export as an image.
Text must be selectable inside the file.
Single-column layout, no tables or text boxes.
File name scheme: CV_Lastname_Role.
Respect the portal's size limit.
Keep the original file for future tailoring.

Conclusion

PDF is the right default, DOCX the sensible exception. If you create either one properly, the format costs you nothing. What matters is what the document says and how it is structured.

The fastest way to see whether your file is really readable and which terms from the job ad are still missing is to compare your CV against the ad.

Frequently asked questions

Is PDF or Word better for an ATS?

Modern systems read both. PDF is the standard in Germany; only send DOCX when the job ad or a recruitment agency asks for it.

Can an ATS read a PDF at all?

Yes, as long as it contains real text. Only scanned PDFs or PDFs exported as images are empty for a system. Check by selecting and copying the text inside the PDF.

Should I merge all documents into one PDF?

For email applications, one merged file with cover letter, CV and references is common. In portals, upload the documents separately in the fields provided.

How large may the file be?

Stay below 2–5 MB where possible. Many application portals reject larger attachments. Reduce the resolution of your photo and scanned references instead.
