Sign Any PDF Free. Draw, Type, or Upload Your Signature. No Adobe, No Printer.
You have a PDF that needs your signature. No printer nearby. No scanner. No Adobe Acrobat subscription. No problem.
RepetiGo's free PDF signing tool lets you sign any PDF directly in your browser - draw your signature with a mouse or finger, type your name in a signature font, or upload a photo of your handwritten signature. Works on Mac, iPhone, Android, and Windows. Sign and send in under two minutes.
Three Ways to Sign a PDF - Draw, Type, or Upload.
You can add your signature to a PDF in three ways. Each works on every device - choose whichever fits how you work:
| Method | How It Works | Best For | Works On |
|---|---|---|---|
| Draw | Freehand signature drawn with mouse, trackpad, or finger. Looks just like a handwritten signature. | Contracts, legal documents, any situation where a natural-looking handwritten signature is expected. | Mac (trackpad), iPhone/iPad (finger or Apple Pencil), Android (finger), Windows (mouse or stylus) |
| Type | Type your name and choose a signature-style font. Clean, professional appearance. | Business agreements, HR documents, forms where legibility matters more than handwriting style. | All devices - keyboard input on any platform |
| Upload | Photo or image of your existing handwritten signature (JPG or PNG). Crops and places exactly on the PDF. | Legal documents requiring your verified signature, formal agreements, situations where signature consistency matters. | All devices - upload any existing signature image file |
Electronic Signature vs Digital Signature - What Is the Difference?
These terms are used interchangeably in everyday speech, but they mean different things. Knowing the distinction helps you choose the right approach for your situation:
| Type | What It Is | Legal Status | When to Use |
|---|---|---|---|
| Electronic Signature | A visual representation of your signature applied to a PDF - drawn, typed, or uploaded. No cryptographic certificate involved. | Legally valid for most everyday contracts and agreements in most jurisdictions (eSign Act in the US, IT Act in India). Accepted by the vast majority of businesses and individuals. | Employment contracts, NDAs, rental agreements, purchase orders, HR onboarding, vendor agreements - everyday professional and personal documents. |
| Digital Signature (Cryptographic) | A mathematically verified signature using a public/private key certificate (PKI). Provides tamper-evidence and identity verification. Issued by a Certificate Authority. | Required by specific regulated use cases - government filings, legally notarised documents, some financial instruments. Higher assurance level but more setup required. | Government e-filing, MCA21 filings, Aadhaar-based eSign (India), court submissions, regulated financial documents. |

How to Sign a PDF on Mac Free.
macOS has two built-in options - Preview and Safari - but neither offers the draw-on-screen, type-your-name, or upload-image flexibility of RepetiGo. Here is how each option compares:
- Preview (free, built-in): Can create a signature using your Mac's camera (show your handwritten signature on paper) or using the trackpad. Limited font/style options. No upload from file. Works for basic signing.
- RepetiGo (free, browser): Draw with trackpad, type in styled font, or upload an existing signature image. More control over placement and size. Works in Safari or Chrome - no installation.
- Adobe Acrobat Pro (paid): Full-featured. Subscription required.
To sign a PDF on Mac with RepetiGo: open Safari or Chrome, go to Open PDF Tool upload your PDF, use the trackpad to draw your signature or type it, and download the signed document. The whole process takes under two minutes.
How to Sign a PDF on iPhone and Android.
Signing PDFs on mobile is seamless with RepetiGo - no app installation required. Open the tool directly in your phone's browser.

Sign PDF Without Adobe Acrobat.
Adobe Acrobat Pro and Adobe Sign can add signatures to PDFs, but both require a paid subscription. Adobe Reader (the free version) can sign interactive forms with a signature field, but cannot add a signature to a flat PDF that does not already have a signature field.
RepetiGo signs any PDF without Adobe - regardless of whether it has a signature field or not. Draw, type, or upload your signature, place it anywhere on the document, and download. Free, in any browser, no installation.

Who Needs to Sign a PDF?
PDF signing is now a daily workflow for almost every professional:

Your PDF Is Safe. Always.
The documents you sign - employment contracts, agreements, legal forms - are among the most sensitive files you handle. Here is exactly what happens:
- 🔒 Encrypted upload: TLS encryption in transit. Cannot be intercepted.
- 🔐 Isolated processing: Your file processes in a temporary session with no link to any account or identifier.
- 🗑️ Auto-deleted in 60 minutes: Both your uploaded PDF and the signed output are permanently deleted within 60 minutes.
- 👁️ Content never read: The signing engine places your signature image at the specified position on the PDF. It does not read, store, or extract the content of your document.
- 🚫 No account = no data: No sign-up means we hold zero personal data about you or your documents.
PDF Signing for Print Shops.
Print shops and CSC centres increasingly field requests from customers who need to sign a PDF and have it printed immediately - a job application, a government form, an agreement. The manual workflow: the customer produces the PDF on their phone, the operator handles it, prints it, and the customer signs on paper. PrintPilot - RepetiGo's document shop automation platform - allows customers to sign digitally via QR-code upload, so the fully signed PDF goes directly to the print queue without the operator touching the customer's personal document.
Common Questions About Signing PDFs.
Q1: How do I sign a PDF for free without Adobe?
Q2: What are the three ways to sign a PDF?
Draw: freehand with mouse, trackpad, or finger - most natural, looks like a handwritten signature. Type: your name in a styled signature font - clear and consistent. Upload: a JPG or PNG photo of your handwritten signature - places your exact real signature on the document. All three methods work on every device.
Q3: Is an electronic signature on a PDF legally valid?
Yes, for the vast majority of everyday documents - employment contracts, NDAs, rental agreements, purchase orders, and general business agreements. The US Electronic Signatures in Global and National Commerce Act (eSign Act) and India's IT Act 2000 both recognise electronic signatures as legally binding. Some specific regulated contexts require a PKI-based digital signature certificate - for those, you need a Certificate Authority-issued DSC.
Q4: How do I sign a PDF on iPhone?
Open Safari on your iPhone, go to Open PDF Tool and upload your PDF from the Files app. Tap where you want your signature, draw it with your finger, and download the signed PDF. No App Store installation required. The signed file goes directly to your iPhone's Files app for sharing.
Q5: How do I sign a PDF on Mac without Adobe?
Open Safari or Chrome on your Mac, go to Open PDF Tool upload your PDF, and draw your signature using the trackpad or type it in a signature font. Download the signed PDF. No software installation, no Adobe licence. The entire process takes under two minutes.
Q6: Can I sign a PDF on Android?
Yes. Open Chrome on your Android phone, go to Open PDF Tool upload your PDF from the Files app, draw your signature with your finger, and download the signed document. Works on all Android phones - Samsung, Google Pixel, OnePlus, and others. No app installation required.
Q7: What is the difference between an electronic signature and a digital signature?
An electronic signature is a visual representation of your signature placed on a PDF - drawn, typed, or uploaded. Legally valid for most contracts. A digital signature is a cryptographic certificate-based signature that provides mathematical verification of identity and tamper-evidence - required for specific regulated use cases like government e-filing. For everyday professional and personal documents, an electronic signature is exactly what you need.
Q8: Can I fill in a PDF form and sign it in one step?
Yes - use both tools in sequence. First, go to RepetiGo's PDF Form tool at /pdf-tools/pdf-forms to fill in all the form fields. Download the filled form. Then upload the filled PDF to the Sign PDF tool, add your signature, and download the fully completed and signed document.
Q9: Can I edit a PDF after signing it?
Signed PDFs are typically locked against editing - this protects document integrity after signing. If you need to make changes to a signed PDF: open the PDF in RepetiGo's Edit PDF tool at /pdf-tools/edit-pdf, make your corrections, download the edited unsigned version, and then re-sign the corrected document using the Sign PDF tool. Never alter a document after signing without re-signing it.
Q10: Is it safe to upload a contract or legal agreement to sign online?
With RepetiGo, yes. Your file uploads over TLS encryption, processes in an isolated temporary session, and is permanently deleted within 60 minutes of upload. The signing engine places your signature on the PDF without reading, storing, or analysing the document content. No sign-up means we hold no data about you or your documents.
