Is Signvert really free?

Yes, completely. There are no paid tiers, no credit card required, and no hidden charges. The tool runs entirely in your browser using open-source libraries.

Does my document get uploaded or stored anywhere?

No. Your PDF is loaded directly into your browser's memory and never sent to any server. The signed document is downloaded straight to your device. Nothing is stored by us.

What file types are supported?

Signvert supports PDF files, Word documents (.docx), and images (JPG, PNG). You can also convert Word to PDF, merge PDFs, split PDFs, compress files, and more using the free tools.

Can I sign a document on my phone?

Yes. Signvert works in any modern mobile browser (Safari on iPhone, Chrome on Android). You can draw your signature with your finger directly on the touchscreen.

Is a signature made with Signvert legally valid?

That depends on the laws of your country and the requirements of the specific document. For everyday purposes — signing a tenancy agreement, a consent form, or a work document — a signature image is generally accepted. For formal legal or financial documents, check with the receiving party or a legal professional about their specific requirements.

What is the maximum file size?

You can upload PDFs and documents up to 50 MB. Most everyday documents are well under this limit.

Can I convert a scanned PDF to Word?

Yes. The PDF to Word tool uses Tesseract.js OCR to automatically detect and extract text from scanned PDFs. It supports over 20 languages including English, French, German, Spanish, Chinese, and Arabic.

How many PDFs can I merge at once?

There is no fixed limit on the number of PDFs you can merge. In practice, merging very large files may be slow since all processing happens in your browser. For best results, keep individual files under 50 MB each.

Will the merged PDF lose any formatting or images?

No. Signvert merges PDFs at the binary level using pdf-lib, which preserves all pages exactly as they appear in the originals, including images, fonts, and layout.

Are my PDFs uploaded to a server?

No. All merging happens locally in your browser. Your files are never transmitted to any server and are discarded as soon as you close or refresh the tab.
