Resume format PDF: export and quality checks
A4 | One column | 10.5-12 pt body text | Under 1 MB
Text-based, not an image: Open the PDF and try selecting a line of text. If you can't, the ATS can't read it either. Export from a builder or word processor; never scan or photograph a printout.
Single column with standard headings: Summary, Skills, Experience, Projects, Education, Certifications. Multi-column designs can be read in the wrong order.
Embedded fonts and real links: Use common fonts and make email, LinkedIn and portfolio links clickable.
Size and length: Keep the file under about 1 MB. One page for freshers, two pages for experienced candidates.
File name: Firstname_Lastname_Resume.pdf, or include the role, for example Priya_Nair_Operations_Resume.pdf.
Final check: Open it on your phone and in a browser to confirm nothing shifted or got cut off.
