Drop your ZIP or HTML file here
or click to browse — supports .zip, .html, .htm
Drop a .zip archive of your HTML template or a single .html file into the upload zone. Or switch to "Paste HTML" and paste your source directly.
Select which checks to run — SEO, Accessibility, Code Quality, and Performance are all enabled by default. Click "Run Audit" to start.
Browse the issues list filtered by severity or category. Each issue includes a description and fix suggestion. Export the full report as JSON for integration into CI pipelines.
Each file receives a score from 0–100 based on the number and severity of issues found. Errors weigh more than warnings. The overall score is the average across all audited files.
The HTML Template Auditor scans HTML files for common issues across four categories — SEO, Accessibility, Code Quality, and Performance — entirely in the browser. It is designed for ThemeForest sellers, front-end developers, and anyone who needs a quick quality gate before publishing an HTML template.
No. All processing happens entirely in your browser using the File API and JavaScript. Your HTML and ZIP files never leave your machine — there is no upload, no server-side processing, and no storage of your code anywhere.
All .html and .htm files found at any depth within the ZIP are included in the audit. Files inside subfolders are detected and listed. The results tab lets you switch between individual files or view all issues combined.
The tool processes ZIP files entirely in the browser using the JSZip library. There is no enforced file size limit in the tool itself — practical limits depend on your browser and available RAM. ZIPs up to 50MB work reliably in modern browsers. Very large ZIPs with hundreds of files may take a few seconds to parse.
Each issue carries a point penalty: errors deduct 10 points, warnings deduct 3 points, and info-level findings deduct 1 point. The score starts at 100 and is floored at 0. Scores across multiple files are averaged to produce the overall score. Disabled audit categories are excluded from scoring.
Yes. The auditor covers many of the quality criteria that ThemeForest reviewers check — missing meta descriptions, images without alt text, inline styles, console.log statements left in production JS, missing viewport meta tags, and broken relative links. Fixing all errors and most warnings significantly improves approval chances.
The exported JSON includes the overall score, per-file scores, and the full issue list with: file path, rule ID, category, severity, description, and fix suggestion. This format is suitable for integration into automated CI pipelines or for sharing audit results with a team.
Before publishing or submitting an HTML template, running a quick audit catches the issues that are easiest to miss — a missing <meta name="description">, an image without an alt attribute, a console.log() left in the JavaScript. Small issues like these affect SEO, accessibility scores, and marketplace reviews alike.
SEO issues in a template affect every site that uses it — if the title tag is missing or the meta description is absent, every site built from that template ships without them. Accessibility failures are similar: one missing label on a form can block screen reader users across hundreds of deployments. Catching these at the template level is far more efficient than fixing them across individual sites.
