Contact Us

CompareStack is operated by the CompareStack team at comparestack.in. We read every message about tools, documentation, privacy, or business inquiries. Use the channels below so we can route your request quickly.

Who you are contacting

Site: https://comparestack.in
Operator: CompareStack Editorial / support team
Primary email: support@comparestack.in

We typically respond within a few business days. Complex file-processing issues may take longer if we need a reproducible sample.

General support

Email support@comparestack.in with:

  • The tool name (for example, PDF Compare or JSON Formatter)
  • What you expected versus what happened
  • Browser and device (if it is a display issue)
  • Screenshots or a redacted sample when safe to share

Do not email production passwords, private keys, or regulated personal data. Redact secrets from logs and uploads before sharing.

Quick troubleshooting

  • Upload fails or times out: Check the file size limit on the tool page, try a smaller export, and confirm a stable connection.
  • Empty or garbled PDF diff: Confirm the PDF has selectable text; scanned pages may need OCR before comparison.
  • JSON marked invalid: Look for trailing commas, smart quotes, BOM characters, or truncated log lines.
  • Noisy text diffs: Normalize line endings (CRLF vs LF) and trim trailing spaces before comparing again.

Privacy and data questions

For cookies, advertising, uploaded files, or logs, read our Privacy Policy first. For requests not covered there, email support@comparestack.in with the subject line “Privacy.”

Advertising and sponsorship

CompareStack displays third-party ads, including Google AdSense, on select pages to keep core tools free. For direct sponsorship or advertising opportunities beyond programmatic ads, email support@comparestack.in with subject “Advertising,” your proposal, and target audience.

Content corrections

Our tool pages and blog articles are maintained by CompareStack Editorial. If you find inaccurate instructions, broken links, or outdated limits, tell us so we can update the guide for everyone. Include the page URL and a short description of the fix.

Feature ideas

We prioritize documentation and tool improvements based on real workflows. Describe the problem you are solving, the file types involved, and any constraints (offline policy, size limits, team size). We cannot promise every request, but we read them.
