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 much can I reduce the file size?

It depends on the content. Image-heavy PDFs and high-resolution photos can often be reduced by 50-80%. Text-only PDFs with minimal images may see smaller reductions. Use the quality slider to balance size and visual quality.

Does compressing a PDF reduce its quality?

Compression works by re-encoding embedded images at a lower quality. Text, vector graphics, and document structure are not affected. For most business documents, a quality setting of 70-80% produces output that looks identical on screen.

Is my file uploaded to a server during compression?

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

How it works

Signvert's compress PDF online free tool reduces the file size of PDFs and images directly in your browser, with no server upload required. For images, you can adjust the output quality and maximum dimensions using simple sliders and see the estimated file size before downloading. For PDFs, the tool re-encodes embedded images at a lower quality to shrink the overall file size. The entire compression process runs locally using open-source libraries, keeping your documents completely private.

Who uses this tool
