PDF or Word? The Best CV File Format for ATS (and What Breaks It)
Which file format to send your CV in, why a text-based PDF is the safe default, when Word is the better answer, and the file mistakes — scans, images, unusual fonts, huge files — that make a CV unreadable.
It sounds like a trivial detail, and it is one of the most common reasons an application never arrives properly. The format itself is rarely the problem — how the file was produced is. A PDF exported from a word processor and a PDF made by photographing a printout are the same format and completely different documents to any system that has to read them.
The short answer
- Default: a text-based PDF. It keeps your layout identical everywhere and is readable by modern parsers.
- If the advert asks for .doc or .docx: send that. An explicit instruction always wins over general advice.
- If you are pasting into an online form: paste plain text and check the result instead of trusting the preview.
- Never: a scanned PDF, a photo, a screenshot, .pages, or a design file exported as an image.
How to tell whether your PDF is readable
Open it, select all the text, copy it, and paste it into a plain text editor. If nothing is pasted, your CV is an image and no system can read a word of it. If text appears but the order is scrambled, your layout is the problem, not the format.
If you cannot copy the text out of your CV, neither can the company you are applying to.
Problems that have nothing to do with PDF versus Word
- Text inside images: a header designed as a graphic takes your name and job title out of the readable text.
- Contact details in the page header or footer: frequently dropped during extraction.
- Exotic or icon fonts: characters come out as boxes, and ligatures break so efficient becomes ef cient.
- Heavy files: a 15 MB CV full of high-resolution graphics is sometimes rejected by upload limits before anyone sees it.
- Password protection or restricted permissions: a protected PDF can refuse text extraction entirely.
- A file name like cv_final_v7(2).pdf — not a technical failure, but it is the first thing a human sees.
Practical rules for the file itself
- Export to PDF from your word processor or CV builder — do not print and scan.
- Keep it under about 2 MB; compress images rather than the text.
- Use a common font: Calibri, Arial, Helvetica, Georgia, Lato, Open Sans, Noto.
- Name the file with your name and role: Ahmad-Sakka-Data-Analyst-CV.pdf.
- Check the copied-out text once after every export, especially after changing the template.
What about photos in the CV?
A photo is fine in Germany, France, Spain and most of the Gulf, and discouraged in the UK, Ireland, the US, Canada and Australia. Either way the photo must be an extra, never a container for text: keep your name, title and contact details as real text next to it.

Is PDF or Word better for a CV?
A text-based PDF is the safer default because the layout cannot shift. Send Word only when the job advert or the portal explicitly asks for it.
Can an ATS read a PDF?
Yes, modern systems read text-based PDFs reliably. What they cannot read is a scanned or image-based PDF with no text layer.
What size should a CV file be?
Under about 2 MB. Large files come from uncompressed images and can hit upload limits on application portals.
