PDF is the preferred resume format for most job applications in 2026, but not all PDFs are created equal. A PDF that looks perfect on screen can be completely unreadable by an ATS if it was created the wrong way. The ATS does not see your resume the way you do - it reads raw text, and if that text was converted incorrectly or embedded as an image, the system will fail to parse it and your application may be discarded automatically. This guide explains exactly how to create a PDF that both humans and machines can read.
Try It FreeThe first is selectable text - text that the PDF stores as actual characters, which means you can click into the document, highlight a word, and copy it. The second is an image of text - the PDF stores a visual picture of the page, and what looks like text is actually a photograph of letters. An ATS parser can read the first type and cannot read the second. Test your PDF before submitting by opening it and trying to select and copy a sentence. If you can highlight individual words, the text is machine-readable. If your cursor cannot grab the text, you likely have an image-based PDF that will fail ATS parsing. This simple test takes 10 seconds and can save your application.
These applications store text as actual characters and produce text-based PDFs when you export them. Resume builders that emphasize visual design - Canva, Novoresume, Enhancv, and similar tools - frequently export image-based PDFs or PDFs with embedded graphics that cause parsing errors. If you prefer a visually designed resume for networking or direct email submissions, maintain two versions: one designed version for personal use and one clean text-based version for ATS applications. Use the text-based version for any online application that goes through a company portal or ATS.
The most common problem areas are: document headers and footers (the zones outside the main page body), text boxes placed anywhere in the document, tables used for layout rather than data display, and decorative elements like horizontal lines created with drawing tools rather than with a standard paragraph border. Before exporting your resume to PDF, place all your content - including your name, contact information, and section headings - inside the main document body. Delete any text boxes and retype their contents directly into the document. Remove any tables used for layout and replace them with tab stops or simple line breaks. These steps take 10-15 minutes but ensure the ATS reads everything you wrote.
In Google Docs, go to File > Download > PDF Document (.pdf). This is the most common way to accidentally create an image-based PDF. If someone asks you to 'just send a PDF of your resume,' always create it through the Word or Google Docs export function.
Then copy and paste the selection into a plain text file or a blank document. Read through what you get. The pasted text should contain all your information in a logical reading order: name, contact info, summary, work history, education, skills. If sections appear scrambled, out of order, or partially missing, the ATS will parse your resume incorrectly. Common problems to look for in the pasted text: contact information missing because it was in a document header; skills section appearing in the middle of a work experience entry because of a two-column layout; company names and dates appearing on separate lines from the job title because of a table-based layout. Each of these indicates a structural issue you need to fix before submitting.
A well-formatted text-based resume should be well under 1MB. If your PDF is larger than 2MB, you likely have embedded images or other non-text content adding to the file size. Remove any logos, photos, icons, or decorative graphics. Name your file professionally: FirstnameLastname-Resume.pdf or FirstnameLastname-JobTitle-Resume.pdf. File names like Resume_Final_v3_ACTUAL_FINAL.pdf or just resume.pdf look careless to human reviewers and can cause sorting problems in applicant tracking systems. A clean file name takes seconds to set and makes a small but meaningful impression.
Check your resume against any job description in under 60 seconds.
Add to Chrome for FreePDF is generally preferred for most applications because it preserves your formatting exactly as intended and cannot be accidentally altered. However, some job postings explicitly request a Word document (.docx) - in those cases, submit what was requested. A few older ATS systems parse Word documents more reliably than PDFs. When the posting does not specify a format, default to a text-based PDF created from Word or Google Docs.
Visually designed templates with icons, colored sidebars, and graphics are high-risk for ATS parsing. The icons are images that the ATS cannot read. Colored sidebars are often built with text boxes or tables that confuse parsers. If you want to use a designed template, test it by copying all the text from the exported PDF and checking that everything parses correctly. If the text is scrambled or incomplete, use a simpler format for ATS submissions.
Standard fonts like Arial, Calibri, Times New Roman, Georgia, and Helvetica are recognized reliably by all ATS parsers. Unusual or decorative fonts can sometimes cause character recognition issues in older ATS systems. Stick to a standard font in 10-12pt for body text. Avoid symbol fonts, script fonts, or any font that encodes characters differently from standard Unicode. These can cause the ATS to output garbled text where your carefully chosen words should be.
