Terms of use

StackPDF is a set of PDF tools on stackpdf.com and in the StackPDF apps for iPhone and Android. By using it, you agree to these terms.

Only open files you have the right to use. You are responsible for what you do with the tools and with the files they make.

• The free plan includes 1 PDF export a day with the tools that run in your browser. The count starts again the next day.
• You don’t need an account, and results never get a watermark.
• Cloud tools and storage in your cloud library are part of Premium.

Premium costs $5.99 a month or $39.99 a year, in US dollars. It gives full access to every tool, including Convert PDF to PDF/A, PDF to Word, PDF to Excel, PDF to PowerPoint, PDF to CSV, Word to PDF, Excel to PDF, PowerPoint to PDF, HTML to PDF and OCR PDF, within the fair-use limits below.

• On the web, you need an account to buy Premium. The same account works in the apps.
• Premium renews at the end of each month or year until you cancel.
• Cancel any time in Account, then Billing. Premium stays on until the end of the period you paid for, and you aren’t charged again.
• If you bought Premium in the iPhone or Android app, the App Store or Google Play handles billing, cancelling and refunds.
• Premium is for your own use. Don’t share, resell or script access to a paid account.

Premium is full access, not unlimited use. These limits stop any one account from running up costs, and most people never reach them. When you reach one, the tool says which limit and when it resets.

We may change these limits. This page always shows the current ones. Tools that run in your browser don’t count toward them.

Your files stay yours. We only handle a file to do the job you asked for, and the privacy policy explains how.

• Tools that run in your browser never send your file to us.
• Cloud tools delete your file and the result after the job, within a day at most.
• Your cloud library keeps files until you delete them. If Premium ends, it turns read-only and stays downloadable for 90 days, then the files are deleted.

Keep your own copy of anything important. StackPDF is not a backup service.

• Breaking the law, or processing files you have no right to use
• Uploading malware, or files built to harm our systems or other people
• Using HTML to PDF to reach private or internal systems
• Getting around the limits, the security checks or Premium
• Using the cloud library as public file hosting

We work to keep StackPDF available and correct, but the tools are provided as they are. Check important results before you rely on them.

We may change or retire a tool, and we may pause a cloud tool to protect the service. Tools that run in your browser keep working when cloud tools are paused.

You can delete your account at any time in Account, then Settings. This deletes your account and your cloud library. If you pay through the App Store or Google Play, cancel there first.

We may block an account that breaks these terms.

When these terms change, we update this page and the date at the top.
