If you are applying for jobs online, you have probably wondered how well your resume performs before submitting it.
That is exactly what ATS resume scanner tools are designed to do. They analyze your resume against a job description and estimate how likely it is to pass applicant tracking systems.
This guide compares the best ATS resume scanner tools in 2026 and explains how to choose the right one.

An ATS resume scanner is a tool that evaluates your resume by comparing it to a job description.
It typically provides:
- ATS match score
