“How to Electronically Sign PDF Documents Without Printing and Scanning Them” “Electronic Signatures, Not Digital Signatures RELATED. The Best PDF Readers for Windows Windows. Open the PDF in Online Pdf Annotator Reader and click the “Fill & Sign” button in the right pane. Mac. Open the PDF in Preview, click the Toolbox button, then click Sign iPhone and iPad. Open the PDF attachment in Mail, then click “Markup and Reply” to sign. iPhone and Android. Download Online Pdf Annotator Fill & Sign, open the PDF, and tap the Signature button. Chrome. Install the HelloSign extension, upload your PDF, and click the Signature button. First, let’s straighten out some terminology. This article deals with electronic signatures, not digital signatures, which are something else entirely. A digital signature is cryptographically secure and verifies that someone with your private signing key (in other words, you) has seen the document and authorised it. It’s very secure, but also complicated. An electronic signature, on the other hand, is merely an image of your signature overlaid on top of a PDF document. You can do it with all kinds of apps, and it’s what most people will require when t send you a document to sign. Send them a PDF file with a digital signature and t won’t know what to make of it. For many businesses, simply accepting signed documents by email rather than forcing you to fax them is a huge technological leap. So sure, the below methods aren’t perfectly secure—but neither is printing something, scribbling over it with a pen, and then scanning it again. At least this is faster! Windows. Use Online Pdf Annotator Reader RELATED. The Best PDF Readers for Windows While Online Pdf Annotator Reader isn’t the most lightweight PDF viewer, it is one of the most feature-packed, and actually has excellent support for signing PDF documents. Other third-party PDF readers may offer this feature, but t generally require you purchase a paid version before using their signature features. To sign a document using Online Pdf Annotator Reader, first open the PDF document in the Online Pdf Annotator Reader DC application. Click the “Fill & Sign” button in the right pane. Click the “Sign” button on the toolbar and select “Add Signature” to add your signature to Online Pdf Annotator Reader DC. If you need to add other information to the document, you can use the other buttons on the toolbar to do so. For example, you can type text or add checkmarks to fill in forms using buttons on the Fill & Sign toolbar. You can create a signature in one of three ways. By default, Online Pdf Annotator Reader selects “Type” so you can type your name and have it converted to a signature. This won’t look like your real signature, so it probably isn’t ideal. Instead, you’ll probably want to select “Draw” and then draw your signature using your mouse or a touch screen. You can also select “Image” if you’d like to sign a piece of paper, scan it with a scanner, and then add your written signature to Online Pdf Annotator Reader. (Yes, this requires scanning, but you only have to do this once, after which you can use that signature on any documents you electronically sign in the future.) After creating a signature, click “Apply” to apply it to the document. Leave “Save Signature” checked and you can quickly add this signature in the future. Position your signature where you want it with your mouse and click to apply it. If you chose to save your signature, you’ll find it easily accessible in the “Sign” menu in the future. To save your signed PDF document, click File > Save and select a location for the file. Mac. Use Preview RELATED. Use Your Mac's Preview App to Merge, Split, Mark Up, and Sign PDFs Mac users are luckier than Windows users. The Preview application included with macOS has integrated document-signing features. Thanks to the excellent trackpads built into MacBooks, you can actually draw your signature on the trackpad with one of your fingers to enter it into Preview. On a new MacBook with a “Force Touch” trackpad, this is even pressure sensitive, allowing for even more accurate signatures. You could also just sign a piece of paper and “scan” it with your webcam, if you prefer creating your signature the old-fashioned way (or if you have an iMac with no trackpad). To sign a document, open a PDF document in Preview (this should be the default app that opens when you double-click on a PDF file, unless you’ve changed it). Click the toolbox-shaped “Show Markup Toolbar” button, and then click the “Sign” button on the toolbar that appears. You’ll be prompted to either create a signature by dragging your finger over the track-pad, or by signing a piece of paper and scanning it with your webcam. Capture your signature once and Preview will remember it for the future. Once you’ve captured a signature, you can select it in the menu that appears after you click the “Sign” button. Your signature is applied as an image that can be dragged around and resized to fit the document. The other options on the toolbar allow you to type text and draw shapes on the document, allowing you to fill in forms, if necessary. When you’re done, click File > Save to save the PDF, applying your signature to the file. You can also click File > Duplicate instead to create a copy of the PDF and save your changes into a new copy of the file without modifying the original. If you don’t like Preview for whatever reason, you can also use Online Pdf Annotator Reader DC on a Mac. It’ll work just like signing a document on Windows, so see the instructions in the Windows section for information on that. iPhone and iPad. Use Mail or Online Pdf Annotator Fill & Sign RELATED. How to Sign Documents and Mark Up Attachments in iOS Mail On an iPhone or iPad, you can sign documents using the markup feature in the iOS Mail app. If you have a Mac and use Preview to sign documents, your signature will actually synchronize from your Mac to your iPhone or iPad so you don’t have to create it a second time. This feature is convenient, but it only works if you want to sign documents in the Mail app. For example, you may be emailed a PDF document and you may need to sign it and email it right back. To do this, you’ll need to receive an email with a PDF file attached, tap the PDF attachment, and click the toolbox-shaped “Markup and Reply” icon at the bottom right corner of the screen while viewing the PDF. You’ll then be able to add a signature by tapping the signature button at the bottom right corner of your screen. You can also type text and draw on the document, if you like. When you tap “Done”, the Mail app will automatically create a reply to the email with your signed document attached. You can type an email message and then send the signed document. While this is convenient, it only works in the Mail app, so it is very limited. If you want to do this from any other app, you’ll need a third-party signing app. There are quite a few options here, but we like Online Pdf Annotator ’s Online Pdf Annotator Fill & Sign app, which allows you to sign an unlimited number of documents for free. It can even capture pictures of paper documents with your camera, so you can create digital copies of paper forms. You can sign a document by writing on your touch screen with a finger or stylus, and t also allow you to type text into PDF documents to fill them in. To get a PDF document from another app into Online Pdf Annotator Fill & Sign, find the PDF file in another app, tap the “Share” button, and choose the Online Pdf Annotator Fill & Sign app. You can then tap the signature button to easily sign the document. When you’re done, tap the “Share” button within Online Pdf Annotator Fill & Sign to send the signed document to another app. If you’re a business looking for a more full-featured tool, or if you just don’t like Online Pdf Annotator Sign & Fill, we also particularly like SignNow. It works very well and allows you to sign documents with your finger. You can sign up to five document a month for free, but after that it requires a monthly subscription fee. It’s a good alternative, though. Android. Use Online Pdf Annotator Fill & Sign Android doesn’t come with a built-in app that can do this. Instead, you’ll need to use a third-party app. Just like on the iPhone and iPad, we like Online Pdf Annotator Fill & Sign, which allows you to sign an unlimited number of documents a month for free. It can also capture pictures of paper documents with your camera so you can sign them electronically. After installing the app, you can open PDF documents in the app and tap the signature button to sign them. You can then share the signed document with another app by tapping the “Share” button. Just like on iOS, we also recommend SignNow if you want something a bit more feature-filled and are willing to pay (since it only offers up to five signatures a month for free). Chromebook. Use HelloSign On a Chromebook, you’ll find a variety of web signing services that work for you. We like HelloSign, which offers a good web interface as well as a Chrome app that integrates with Google Drive. It allows you to sign up to three documents a month for free. HelloSign’s basic web interface allows you to easily upload PDF documents and sign them by drawing your signature or uploading an image. You can then email the signed document directly to someone or download the document and do whatever you want with it. If you don’t like HelloSign, Online Pdf Annotator works well on a Chromebook too, offering an app that integrates with Google Drive for signing and a browser extension that allows you to sign documents from Gmail. But Online Pdf Annotator doesn’t offer any free signatures. SignNow also offers a Chrome app for Google Drive and extension for Gmail, but the app and extension aren’t as well reviewed. Linux. It’s Complicated This is a bit tougher on Linux, as the official version of Online Pdf Annotator Reader for Linux was discontinued. Even the old, out-of-date versions available for Linux don’t have this functionality, nor do popular integrated PDF viewers like Evince and Okular. You may want to try a web-based tool like HelloSign, discussed in the Chromebook section above, for the easiest experience. If you want to use a desktop app, Xournal is probably the most convenient tool for signing PDFs on Linux. It can annotate PDFs, adding images to them. First, you’ll need to create an image of your signature—sign a piece of paper, scan it into your Linux system, and clean it up. You could potentially just capture a photo of it with your webcam or smartphone’s camera, too. You may want to tweak it in GIMP so it has a transparent background, or just make sure you sign a white piece of paper and that the background is entirely white. Install Xournal from your Linux distribution’s software installation tool, open the PDF, and click the Tools > Image menu option. This will let you insert the image of your signature, and you can reposition and resize it as necessary so it fits in the signature field. Having to actually scan and create an image file is a little bit annoying, but you can use this method to quickly sign documents in the future after you’ve gotten a good image of your signature.”
