Yes. Every one of AziPDF's 30+ tools is permanently free. There are no subscriptions, no watermarks, no per-file charges, and no registration required. You get unlimited use at zero cost — forever.

AziPDF is 100% browser-based and powered by WebAssembly. Your files never leave your device — nothing is uploaded to any server, logged, or retained. This makes AziPDF the most private PDF tool available in 2026, far safer than server-based tools.

AziPDF converts to and from PDF in both directions: Word (DOC, DOCX), Excel (XLS, XLSX), PowerPoint (PPT, PPTX), images (JPG, PNG, WebP, TIFF), HTML pages, and PDF/A for long-term archiving. All conversions run locally in your browser.

No installation, no plugin. AziPDF works instantly in any modern browser — Chrome, Firefox, Safari, and Edge — on Windows, macOS, Linux, iOS, and Android. Open the page and start working.

Because all processing happens locally on your device, the practical limit is your device's available RAM — not an artificial server cap. Most modern laptops and phones handle PDFs up to 500 MB and thousands of pages without any issue.

Unlike server-based PDF tools like iLovePDF, Smallpdf, and Sejda, AziPDF never uploads your files to a remote server. Many popular alternatives impose daily file limits, add watermarks on free plans, and store your data on their servers. AziPDF has no limits, no watermarks, and zero data retention — your files stay on your device at all times.

Yes. AziPDF's Compress PDF tool offers multiple quality presets — from maximum compression to high-fidelity — so you can reduce file size while preserving readability. The compression runs entirely in your browser with no upload required.

Yes. Once the AziPDF page has loaded in your browser, many tools continue to work even without an active internet connection, because all processing logic is downloaded as a WebAssembly module to your device.
