Frequently Asked Questions

Browser-first tools are used whenever they can produce reliable results directly on your device. Server-backed tools are used for jobs that need heavier processing, better Office document fidelity, saved-file history, usage credits, billing checks, review submission, account sign-in, or admin-controlled features.

Office documents can contain complex page layouts, spreadsheet print areas, custom fonts, images, shapes, headers, footers, charts, and slide masters. A native conversion engine gives much better results than simple browser rendering. This is why Office-to-PDF tools use the high-fidelity conversion service by default instead of a text-only fallback.

Fileza is tuned for high-fidelity conversion and uses native document export filters for Word, Excel, PowerPoint, OpenDocument, Publisher, Visio-style, and related files. In most normal cases, the output should closely preserve the original layout. Exact matching can still depend on the fonts available to the conversion engine, the complexity of the document, and whether the source file uses unusual features or embedded content.

The core tools are available for everyday use. Some account-based features, higher usage limits, saved history, ad-free options, premium tools, credit packs, or future AI-powered document tools may require signing in or upgrading when those features are enabled.

Yes, an internet connection is recommended. Browser-based tools may continue working after the site has loaded, but account features, review submission, usage limits, saved history, billing, admin controls, and high-fidelity Office conversions need the Fileza server or conversion service.

Limits depend on the tool, your device, and your account plan. Guest users may be asked to sign in after a limited number of download/share actions. Server-backed conversions also have practical file-size and processing-time limits to keep the service reliable for everyone.

Failures are uncommon, but they can happen for a few reasons:

• The file may be corrupted, encrypted, password-protected, or not compliant with normal file specifications.
• The document may use missing fonts, unusual macros, external links, unsupported embedded media, or very complex layout features.
• The server conversion worker may be temporarily unavailable or the file may exceed the configured size/time limit.
• Your browser or device may not have enough memory for browser-based PDF actions.

Fileza may record limited technical events such as tool name, success/failure status, processing time, browser type, file type, and file size so we can monitor reliability and improve the service. Account, billing, credit, review, and saved-history features store the information needed to provide those features. We avoid storing document contents unless a signed-in saved-file history feature is deliberately used.
