ComplyLoft PDF Accessibility Checker review
A no-sign-up web checker for structural PDF accessibility checks and summary results.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ComplyLoft PDF Accessibility Checker is a browser-based tool for checking PDF documents against PDF/UA and selected WCAG 2.1 Level AA requirements. It is aimed at users who need a free first pass on PDF structure without creating an account. Uploads can be up to 10 MB, and the tool returns a summary report after processing. It checks tagged document structure, defined reading order, table row, column and header markup, image and figure alternative text, form-field labels, and declared document language.
The checker’s strongest capability is focused automated validation. It uses the veraPDF validator for PDF/UA checks and adds a basic body-text colour-contrast heuristic for text over solid backgrounds. Results are mapped to WCAG 2.1 Level AA guidelines, which can help connect PDF-specific findings with a broader accessibility framework. Uploaded PDFs are deleted after processing, while the web-only delivery keeps the workflow limited to browser-based document checks.
Its scope is deliberately narrow. The free report summarizes results but does not identify individual failures or their locations, so users still need qualified human review to assess the document fully. There is no manual review workflow, remediation guidance, integration support, or CI/CD capability. Choose ComplyLoft PDF Accessibility Checker for a quick structural screening of individual PDFs at no cost; choose a remediation-focused product or a workflow with integrations when teams need detailed correction support, repeatable pipeline checks, or broader review coverage.
