Frequently asked questions

Yes. PdfPix is 100% free, has no paid tier, and processes every file locally in your browser. Files are never uploaded to a server, so your documents stay on your device from start to finish.

No. Because processing happens inside the browser using WebAssembly, the files you upload never reach our infrastructure. There is no analytics pipeline, no remote logging, and no retention. We have no way to see, store, or share your documents.

Browser-based processing is well-suited for sensitive workflows because the file never leaves the local machine. For highly regulated environments, we still recommend running sensitive PDFs from a clean profile or device and following your organization's data-handling policy.

No. We do not add watermarks, branding, banners, or quality reductions to your output. The file you download is the result of the operation you asked for.

No. PdfPix has no signup wall, no email collection, and no login requirement. Open a tool and start working immediately.

Yes. PdfPix is committed to staying 100% free, with no paid tier or hidden subscription. The product is supported by the UTHAKKAN ecosystem, not by user fees.

If PdfPix is useful to you, you can support development through the Sponsor and Donate pages linked in the site footer. Every contribution helps fund new tools and maintenance.

No artificial file size limit. The only practical limits are your device memory and browser stability. Since processing runs locally, very large files work the same as small ones.

The PDF tools accept standard PDF files. Image-to-PDF tools accept JPG, PNG, WEBP, GIF, BMP, and TIFF. Conversion tools also accept DOCX, PPTX, XLSX, and HTML depending on the destination format.

Yes. Use the Unlock PDF tool to remove a known password first, then run the file through any other tool. PdfPix cannot bypass unknown user passwords — that is by design and protects file owners.

Yes, once the page has loaded. Because the processing libraries run in your browser, you can disconnect from the internet and continue working on the file you already opened.

PdfPix currently ships 30+ tools across organize, optimize, convert, edit, security, and AI workflows. The full directory is available on the All PDF Tools page.

Yes. The Edit PDF tool supports adding new text, shapes, and freehand annotations. To edit existing text, you typically convert to Word with the PDF to Word tool, edit there, and convert back.

Yes. The AI PDF Summarizer and Translate PDF tools use language models to extract summaries and translate content while keeping layout context.

Yes. The Sign PDF tool lets you draw, type, or upload a signature and place it on any page. Signatures are applied locally and are not sent to a signing service.
