Free ATS Resume Checker
Don't submit your resume blind. Use this step-by-step guide to check if your resume will pass Applicant Tracking Systems — and learn how AI tools can automate the process for every application.
What Is ATS Checking?
ATS checking is the process of verifying that your resume can be properly parsed, read, and scored by Applicant Tracking Systems before you submit it. Think of it as a pre-flight checklist for your job application.
There are two approaches: manual checking (free, takes 10-15 minutes) and AI-powered checking (automated, takes seconds). We'll cover both so you can choose what works for your situation.
DIY: Manual ATS Check (Free)
You can check your resume's ATS compatibility yourself in 4 steps. This won't give you a match score, but it will catch the most common problems that cause rejections.
Step 1: Formatting Check
Open your resume and check each item:
Layout & Structure
- Single-column layout (no multi-column designs, tables, or text boxes)
- Contact info is in the document body (not in header or footer)
- Standard section headers used: Summary, Experience, Education, Skills
- No images, graphics, charts, or icons anywhere in the document
- Standard bullet characters (round dots • or dashes –)
Typography
- Standard font used (Arial, Calibri, Georgia, Times New Roman, Helvetica)
- Body text is 10-12pt, headers are 12-14pt
- No fancy formatting (shadows, WordArt, colored text beyond basic black)
- Bold and italic used sparingly for emphasis (no underlines)
File Properties
- File is .docx or text-based .pdf (not scanned/image PDF)
- File name is professional (e.g., “Jane-Smith-Resume.docx”, not “resume-final-v3-REAL.docx”)
- File size is under 5MB
Step 2: Keyword Match Analysis
This is the most impactful check. Compare your resume content against the job description to find keyword gaps.
Extract Job Description Keywords
Copy the job description into a text editor. Highlight or list every hard skill, tool, certification, and industry term mentioned. Pay special attention to items in the “Required Qualifications” section.
Check Your Resume for Each Keyword
Use Ctrl+F (Cmd+F) to search your resume for each keyword. Mark whether each one is present, absent, or partially present (e.g., JD says “project management” and you have “managed projects”).
Calculate Your Match Rate
Divide the number of matching keywords by total keywords. Cover every required skill you can honestly claim, then the preferred ones. There is no published pass mark, so add a missing keyword only where it describes work you actually did.
Check for Both Forms
Ensure you include both acronyms and full names: “SEO” AND “Search Engine Optimization”, “PM” AND “Project Management”. ATS systems may search for either form.
Step 3: Parsing Test
This test simulates how an ATS reads your document.
The Plain Text Test
- 1. Open your resume in its original format (.docx or .pdf)
- 2. Select All (Ctrl+A) → Copy (Ctrl+C)
- 3. Open a plain text editor (Notepad on Windows, TextEdit on Mac in plain text mode)
- 4. Paste (Ctrl+V)
- 5. Review the result
What to Look For
- All text is present — nothing was lost in the copy-paste
- Sections are in order — Contact, then Summary, then Experience, etc.
- Bullet points are readable — not jumbled together in a single paragraph
- Red flag: Text from columns mixed together or in wrong order
- Red flag: Missing content (text in headers/footers doesn't appear)
- Red flag: Garbled characters or symbols instead of bullet points
If your resume passes the plain text test cleanly, it will parse correctly in most ATS systems. If text is jumbled, missing, or out of order, you have formatting issues that need fixing.
Step 4: Content Quality Check
Even with perfect formatting and keywords, weak content won't get you interviews. Check these elements:
Do your bullets include numbers?
Do bullets start with power verbs?
Is every bullet relevant to this role?
Remove bullets about skills or experiences that don't connect to the target job. Every line should earn its space.
Can you stand behind every claim?
Tailoring means emphasizing real skills, not inventing fake ones. If you can't discuss a bullet in an interview, remove it.
Common ATS Failures & Fixes
| Problem | Why It Fails | Fix |
|---|---|---|
| Two-column layout | ATS reads left-to-right, mixes columns together | Switch to single-column format |
| Contact info in header | Many ATS skip headers/footers entirely | Move contact info to document body |
| Creative section headers | "My Journey" isn't recognized as "Experience" | Use standard headers: Experience, Education, Skills |
| Scanned PDF | Image-based PDFs have no text for ATS to read | Re-export as text-based PDF or use .docx |
| Tables for layout | ATS may read cells out of order or skip them | Remove tables, use plain text with spacing |
| Missing keywords | Resume doesn't match job description terms | Add relevant keywords to bullets and skills section |
| Keyword stuffing | Modern ATS penalizes unnatural keyword density | Use keywords naturally within accomplishment statements |
| Wrong file format | .pages, .odt, or image files | Convert to .docx or text-based .pdf |
AI Tools vs. Manual Checking
Manual checking is effective for catching formatting issues and obvious keyword gaps. But it has limitations — you can't simulate exact ATS scoring, and it takes 10-15 minutes per application.
| Capability | Manual Check | AI-Powered Tools |
|---|---|---|
| Formatting verification | Yes (with plain text test) | Yes (automated) |
| Keyword matching | Basic (Ctrl+F) | Advanced (semantic matching, synonyms) |
| Match score | No (rough estimate) | Yes (percentage-based scoring) |
| Keyword suggestions | No | Yes (suggests missing keywords) |
| Content rewriting | No (manual work) | Yes (AI rewrites bullets with keywords) |
| Time per check | 10-15 minutes | Under 1 minute |
| Cost | Free | Free tier available / Paid for full features |
| Tailoring | You do it manually | Automated for each job description |
