Sign a PDF online without creating an account
UVs Tool Hub's Sign PDF tool is designed for the common situation where a document needs a visible signature, initials or date but you do not want to print, scan, create an account or upload a sensitive file to a remote signing service. The PDF is opened in your browser, your signature is added to the page you choose, and the finished copy is generated on your device.
Draw, type or upload your signature
Use Draw with a mouse, trackpad or touchscreen for a handwritten signature. Use Type when you want a clean signature-style rendering of your name. If you already have a signature image, choose Upload and use a PNG, JPG or WebP file. The optional white-background cleanup can make a photographed or scanned signature sit more naturally over the PDF instead of appearing inside a white rectangle.
Place the signature where it belongs
After adding a signature to the current page, drag it directly over the signature line or signing area. Select it to reveal a resize handle and adjust its size without changing the original PDF page. You can move to another page and add more signatures or supporting fields before creating the final document.
Add initials, dates and short text
Contracts and approval forms often require more than one signature. The workspace can also place initials, the current or selected date, and short text such as a name, role or note. Each field is independently positioned and resized, which is useful when a form has several small signing areas.
Private browser-based processing
For this tool, the source PDF and signature are processed locally in the browser. There is no external document-conversion service, no login requirement and no need to upload the PDF to UVs Tool Hub just to place the visible signature. This is especially useful for routine contracts, forms and internal approvals where document privacy matters.
Electronic signature vs digital signature
This tool places a visible electronic signature or signature image into the PDF. It does not create a cryptographic certificate-based digital signature and it does not verify identity. Some organisations accept a visible electronic signature for routine documents; others require a dedicated certificate, identity verification or a particular signing platform. Check the recipient's requirements before relying on any signing method for a legally sensitive document.

Tips for a clean signature result
For an uploaded signature, use a tightly cropped image with strong contrast. PNG files with a transparent background usually give the cleanest result. If you photographed a signature on white paper, enable the white-background cleanup and inspect the placement before saving. For drawn signatures, a slightly wider pen line often looks better on high-resolution screens and printed documents.
