Frequently Asked Questions
Everything you need to know about this tool, how it works, and privacy.
Is the CodeASystem Resume Builder really free with no paywall?
Yes. CodeASystem Resume Builder is completely free with no hidden charges, trial periods, subscription fees, or paywalls. You can create, edit, style, and export your resume as an ATS-compliant PDF or JSON file without creating an account or providing payment details.
How does this resume builder keep my personal data private?
Your resume data never leaves your device. All information, edits, and PDF rendering take place entirely client-side in your web browser using local storage. We do not collect, transmit, or store your contact information, employment history, or personal details on any external server.
Are resumes created here compatible with Applicant Tracking Systems (ATS)?
Yes. The builder generates structured, semantic single-column layouts with standard section headings (Experience, Education, Skills, Projects). When exported to PDF, text remains fully selectable and machine-readable, ensuring high parsing accuracy across major ATS platforms like Greenhouse, Lever, and Workday.
Can I import and export my resume as JSON?
Yes. You can export your entire resume configuration as a standardized JSON file at any time. This allows you to maintain local backups, version control your resume in Git, transfer data between devices, or supply structured input to AI assistants. You can import any saved JSON file back into the editor with one click.
How do I export to a clean A4 PDF?
Click the "Export PDF" button in the editor toolbar. The builder applies precise A4 print CSS dimensions (210mm x 297mm) with balanced margins, typography scaling, and embedded fonts. Your browser generates a pixel-perfect, vector-sharp PDF ready for immediate job application submissions.
