Common Support Questions
Why did my PDF conversion or processing fail?
Processing issues are typically caused by corrupted source PDF streams, password-protected or restricted files, unsupported non-standard fonts, or insufficient device browser memory when handling extremely large documents. Try running smaller batches or verifying that the PDF is unencrypted.
Why is a PDF taking a long time to process?
Standard PDFZento tools execute inside your browser using WebAssembly. Processing speed depends directly on your device CPU performance, available system RAM, file complexity, and page count. Closing background browser tabs can free resources for large files.
Which web browsers are supported?
PDFZento is optimized for modern standards-compliant web browsers supporting WebAssembly and Web Workers, including Google Chrome, Mozilla Firefox, Apple Safari, Microsoft Edge, and Chromium-based mobile browsers.
Are my PDF files uploaded to your servers?
No. For our standard suite of local PDF utilities, documents and extracted content are processed locally in your browser memory and are not uploaded to PDFZento servers or third-party processing services.
What should I include when reporting a bug or issue?
Please include the specific tool URL, browser name and version, operating system, a description of what you were trying to do, any error messages displayed, and general document properties (such as approximate file size and page count). Do not send sensitive document contents.
Where can I review your Privacy Policy and Terms of Service?
You can read our comprehensive technical data handling practices in our Privacy Policy (https://pdfzento.com/privacy) and website rules in our Terms of Service (https://pdfzento.com/terms).
What should I do if I did not receive an account verification or password reset email?
Please check your spam or junk folder first. Verification codes are dispatched from [email protected] and expire after 10 minutes. If the code has expired, you can request a new one after a 60-second cooldown. If issues persist, contact [email protected].
