Free ATS Resume Builder

This resume builder is free to use in full — every template, every ATS check and the PDF export, with no account, no watermark and no paid tier to unlock. It runs entirely as JavaScript in this browser: there is no server processing your resume, and nothing is uploaded anywhere.

How the Resume Builder Works

  1. 1. Start from scratch, or bring in an existing resume

    Import a PDF — its text is extracted and shown for review before anything is added — or a JSON file previously exported from this builder, which restores exactly.

  2. 2. Fill in your details, section by section

    Personal details, summary, skills, work history, projects, education, certifications and achievements each have their own editor.

  3. 3. Review the live ATS score

    The score updates as you type and is broken down into the categories listed below, each with the specific issues behind it.

  4. 4. Fix the highest-impact issues first

    A priority list surfaces the findings worth fixing before the smaller ones.

  5. 5. Export the finished resume

    As a PDF with real, selectable text — not a flattened image — or as a JSON file to back up or re-import later.

Build an ATS-Friendly Resume

Most of what an ATS gets wrong comes down to a handful of mechanical choices: section headings a parser recognizes rather than a stylized alternative, one consistent date format throughout, a standard font at a readable size, and margins and line spacing wide enough that extraction does not merge adjacent lines. Icons, emoji, tab characters and stray HTML in your text are also worth avoiding — parsers can drop or misread all four. The checker built into this page looks for exactly these things as you write.

For the full breakdown with examples, see the ATS resume format guide.

What the Builder Checks

Contact & Identity

Whether a recruiter or an ATS can find your name, phone, email and location.

Sections & Structure

Whether every section has a heading a parser recognizes, and nothing is empty.

ATS-Safe Formatting

Font, margins, line spacing, and risky characters like icons, emoji or stray HTML.

Content Quality

Weak verbs, passive voice, and bullets that describe a task instead of a result.

Keywords & Skills

Coverage of the skills and terms a listing for this kind of role is likely to search for.

Length & Density

Whether the document runs long or short for the amount of experience it describes.

Privacy and Browser-Based Processing

Your resume is stored only in this browser’s local storage, not on a server — there is nothing to log in to and nothing for anyone else to see. Importing a PDF or a JSON file is also parsed locally: the file is read by JavaScript running on your device, and none of it is sent anywhere. See the privacy page for the full detail on what this site does and does not collect.

Frequently Asked Questions

Is the ATS Resume Builder free?
Yes. Every template, every ATS check and the PDF export are free and unwatermarked, with no account and no paid tier to unlock.
Do I need an account?
No. There is no account system and no login. Your resume is saved automatically to this browser’s local storage as you work.
Is my resume uploaded anywhere?
No. The builder runs as JavaScript in your browser, and importing a PDF or a JSON file is parsed locally too — nothing is sent to a server at any point.
Can I export my resume?
Yes, two ways: as a PDF with real, selectable text rather than a flattened image, or as a JSON file you can use to back up your data or re-import it later.
Does the builder check ATS-related formatting?
Yes. It scores your resume across six categories — contact and identity, section structure, ATS-safe formatting, content quality, keyword coverage and length — and explains the reasoning behind each finding.
