Click the select file button or drag and drop your PDF file onto the page. Supports PDF documents up to 50MB, suitable for most common PDF files.
Click the 'Create New Signature' button and draw your signature in the signature panel using your mouse or touchscreen. You can adjust pen thickness (thin, medium, thick) and color (black, blue), with support for undo and clear operations until you're satisfied. Created signatures are automatically saved for future use.
Click the '+' button next to a saved signature, or drag it directly to the PDF preview area. The signature will appear on the current page, and you can freely drag to adjust its position. To add signatures to other pages, switch to the target page first.
After selecting a signature, drag it to adjust position and drag corner control points to resize. Each signature has a delete button in the top-right corner to remove unwanted signatures. Multiple signatures can be added to the same page.
After adding all signatures, click the 'Export PDF' button at the top. The system will merge all page signatures into the original PDF, generating a new signed PDF document for download. The exported PDF maintains original quality with all signatures permanently embedded.
Common questions about PDF electronic signatures
Electronic signatures have legal validity in many countries and regions. According to Electronic Signature Laws, qualified electronic signatures have the same legal effect as handwritten signatures. Signatures generated by our tool are permanently embedded in the PDF and can serve as identity verification. However, specific legal validity depends on your local laws and the nature of the document being signed. For important legal documents, we recommend consulting professionals.
No. Our tool is designed as an instant-use service where your PDF documents and signature information are only used temporarily in your current browser session. Once you close the page or complete your operation, all data is automatically cleared without leaving any trace. We cannot access or store your document content.
Absolutely. Our tool supports multi-page PDF document signing. You can use page navigation buttons to switch to any page and independently add one or more signatures to each page. Each page's signature positions are saved, and switching pages won't lose already added signatures. When exporting, all page signatures are correctly embedded in the final PDF document.
Yes. When you create a signature and click 'Complete', the signature is automatically saved to the 'Saved Signatures' list. Next time you need to sign a document, you can directly select previously created signatures without redrawing. You can save multiple different signatures and delete unwanted ones as needed. Signature data is stored in your browser's local storage.
No. We use professional PDF processing technology to embed signatures, ensuring the original PDF quality is unaffected. Signatures are embedded in high quality, remaining clear regardless of scaling. Exported PDF documents can be opened and viewed normally in any PDF reader, with signatures being a permanent part of the document that won't disappear due to different software or devices.
Currently only PDF format documents are supported. The file size limit is 50MB, which is sufficient for most signing needs. If your file is in Word, Excel, or other formats, we recommend converting it to PDF first. If files exceed 50MB, we suggest using PDF compression tools first, or splitting large files into multiple smaller ones for separate signing.
Absolutely. Our PDF signature tool uses responsive design and perfectly supports mobile devices like phones and tablets. On touchscreen devices, you can draw signatures directly with your finger, making it more natural and convenient. All features on mobile devices are identical to the desktop version, including signature saving, multi-page signing, and export. We recommend using modern browsers (Chrome, Safari, Edge, etc.) for the best experience.
The current version doesn't support batch processing. If you need to sign multiple PDF files, you'll need to upload, add signatures, and export them one by one. However, since signatures are automatically saved, you can directly use previously created signatures when signing the second file, greatly improving efficiency.
