These frequently asked questions explain how PDFNova processes files, what the tools can and cannot do, how privacy and security work, and what to check when a conversion fails. Answers are general guidance for using the website and are not professional advice. Keep an original copy of every file, use documents you own or are authorized to handle, and review downloaded results before sharing or relying on them.
Do My Files Leave My Device?
Many PDFNova tools process files locally with JavaScript in the browser, so the selected document is not intentionally uploaded to the website’s server. Some advanced operations may offer optional server processing and will clearly require an upload. Browser extensions, device security software, and managed networks can operate independently, so sensitive documents should still be handled only on trusted devices.
Does PDFNova Require an Account?
Ordinary document-tool use does not require a PDFNova account. The website may offer comments, newsletters, or other optional features depending on the administrator’s configuration, and those features can request contact information. Tool access should not require a visitor to provide a password or profile merely to process a local file. Review the Privacy Policy before using optional submission features.
Does PDFNova Use a Paid Conversion API?
The integrated theme is designed without a required paid third-party document-conversion API. Browser-capable tools use JavaScript libraries, and advanced operations can use optional software installed on the website’s own server. Static libraries may be downloaded from content-delivery networks, which receive normal request information, but the selected document is not intentionally sent to those networks by the tool.
Why Did My Conversion Fail?
A failure can result from file corruption, encryption, unsupported content, an outdated browser, limited device memory, a very large file, a conflicting extension, or missing server software. Refresh the page, update the browser, test a smaller copy, and review the displayed error. Keep the source file unchanged. If the issue continues, contact support with the tool name, browser, file type, size, and exact error text.
Can Every PDF Be Converted Perfectly?
No converter can guarantee perfect reproduction of every PDF. Scanned pages, uncommon fonts, complex tables, forms, annotations, layers, scripts, and proprietary objects can change during conversion. Open the result and compare it with the source. Verify important names, dates, numbers, page order, links, and images. Use specialist software when exact legal, archival, print, or accessibility preservation is required.
How Large Can My File Be?
The displayed tool limit controls the maximum file size accepted by that workflow. Browser processing also depends on available memory, and a device can struggle with a file below the stated limit when it contains many high-resolution pages. Close unused tabs and applications, use a desktop computer for large work, and divide a document into smaller sections when practical. Server tools may enforce separate hosting limits.
Can I Use PDFNova on a Phone?
The theme is responsive and many tools work on modern phones and tablets. Large conversions may be slower because mobile devices have less memory and can suspend a busy browser tab. Keep the screen active during processing, close unused applications, and use a desktop browser for complex or very large files. Always open the downloaded result because mobile file viewers can display documents differently.
Which Browsers Work Best?
Current versions of Chrome, Edge, Firefox, and Safari provide the broadest support. Older browsers may lack file, encryption, canvas, archive, or download capabilities required by advanced tools. Browser extensions that block scripts or downloads can interfere. Update the browser, allow JavaScript for the site, and try a private window when troubleshooting. A tool may still depend on device resources and source-file structure.
Why Does an Office Conversion Need Server Software?
High-quality Word, Excel, or PowerPoint conversion often depends on a full office rendering engine. The theme can use LibreOffice installed on the hosting server for supported operations. If the program is unavailable or the hosting plan blocks command-line software, the tool will report an error. The hosting provider or administrator must install and maintain the required program; browser code cannot silently add it.
What Are QPDF and Ghostscript Used For?
QPDF can support standard PDF encryption, decryption, password changes, and permission settings when installed on the server. Ghostscript can support certain PDF processing and archival workflows. Availability and results depend on server configuration and software version. These programs are optional; browser-only tools remain available without them. Server processing can temporarily upload a file, so review the Privacy Policy first.
Can PDFNova Remove Any Password?
No. The unlock workflow is intended for a file you own or are authorized to manage and requires the correct known password. PDFNova does not provide password cracking or permission to bypass access controls. If the password is lost, contact the document owner or use an authorized recovery process. Repeated guessing can waste time and may violate policies or law.
Is a Visible Signature a Digital Signature?
A visible signature image can show a name or mark on a page, but it is not automatically a certificate-based digital signature. Cryptographic signatures can provide identity and tamper-evidence features that an image alone does not provide. Confirm the receiving organization’s requirements before signing. Do not use a copied signature image to misrepresent another person’s consent or identity.
How Should I Create a Strong Password?
Use a long, unique password or passphrase that is not reused on another service. Store it in a reputable password manager and send it to the recipient through a separate channel from the protected file. Keep an original unencrypted backup in a secure location. PDFNova cannot recover a forgotten password for a strongly encrypted file or container.
Does Compression Reduce Quality?
Compression can reduce file size by changing image resolution, image encoding, metadata, or internal object structure. Text may remain sharp while scanned pages and photographs lose detail. Select settings based on the document’s purpose and compare the output at normal and enlarged zoom. Keep a high-quality original for printing, archiving, or later editing. The smallest file is not always the best result.
Can I Process Confidential Documents?
Browser-local processing can reduce file transfer, but a public website may still be unsuitable for regulated or highly confidential records. Device security, browser extensions, organizational rules, network controls, and optional server features all matter. Confirm that your employer, client, or regulator approves the workflow. Use an authorized enterprise or offline system when the document contains sensitive legal, medical, financial, or identity information.
Where Are Downloaded Files Saved?
The browser normally saves the result in its configured Downloads folder or asks the visitor to choose a location. PDFNova does not control the final folder on the device. Rename files clearly, open them immediately, and move important results into an organized and backed-up location. On shared devices, remove temporary downloads and browser history only when doing so is permitted and safe.
Why Did the Layout Change?
A layout can change because the source uses fonts unavailable to the converter, floating objects, complex tables, custom page sizes, macros, hidden content, or features not represented in the output format. Try a different output type, simplify the source, embed fonts where permitted, or use the original application’s export function. Manual adjustment may be necessary after conversion.
How Do I Report a Bug?
Use the Contact Us page and include the tool name, page URL, browser, operating system, device, file type, approximate size, expected behavior, actual result, and exact error text. Do not attach confidential files or passwords. A redacted screenshot or synthetic sample may help. Mention whether the issue remains after updating the browser and testing without extensions.
Can I Use the Tools for Client Work?
Yes, when you have authorization and the workflow satisfies client, contractual, security, and legal requirements. Keep originals, document settings, review every result, and avoid public tools when a client requires an approved system. PDFNova does not certify compliance or assume responsibility for client records. The professional using the tool remains responsible for quality control and confidentiality.
Are the Tools Free?
The website may provide tools without a direct usage charge, but internet access, device resources, optional hosting features, advertising, affiliate links, or future premium services can involve separate costs. A free public tool does not include guaranteed support, uptime, storage, or enterprise compliance. Review any price or subscription information shown before agreeing to a paid feature supplied by PDFNova or a third party.
How Can I Improve Processing Speed?
Use an updated browser, close unused tabs and applications, process a smaller copy, reduce image resolution before conversion, and avoid running several large jobs simultaneously. A wired or stable connection helps only when assets or server processing are needed; local processing depends mainly on the device. Very large scanned documents may be faster when split into manageable sections.
What Should I Do Before Deleting the Original?
Open the downloaded file, compare it with the source, verify page count and order, check text and images, test links and forms, confirm protection settings, and save a second backup. Do not delete the original merely because the download completed. Important documents should retain an untouched source and, where appropriate, a version history showing how the result was created.
