OmniDocHow to Add an Electronic Signature on iPad
Learn how to add an electronic signature to a PDF on an iPad, what the OmniDoc web version does and doesn't cover, and when to use the desktop client.
If you need to sign a contract, a form or a PDF agreement from an iPad, you probably want to know whether you can do it without printing, scanning and emailing the file back. The answer is yes, but the route depends on what you need. Drawing a signature on a PDF is simple on an iPad using a general PDF markup tool. OmniDoc's own signing tool is a different matter, because the product information describes it as part of the desktop client.
This guide is for readers who have a PDF on an iPad and want a signed copy in a few minutes. It also covers the case where the other party has to sign too. We will be direct about one point: OmniDoc's web version at omnidoc.top is built for document translation, and the PDF signing tool described in OmniDoc's product information is part of the desktop client. That changes which method you should use.
You will leave with a clear method for signing a PDF on your iPad, a way to check the result, and a plan for the cases where a desktop computer or a sign request makes more sense.
How do I add an electronic signature on an iPad? The short answer
Draw or type your signature in a PDF markup tool on the iPad, place it on the signature line, and save the result as a new file. For OmniDoc's own PDF signing tool, use the desktop client on a computer.
| Your situation | What to do | Why |
|---|---|---|
| You need to sign a PDF yourself and it is on your iPad | Draw your signature in a general PDF markup tool and save a signed copy | This works with any markup-capable viewer, so the signing step doesn't depend on OmniDoc |
| Other people must sign the file | Send the PDF with OmniDoc's sign request feature so they can sign online | Recipients sign online and you don't have to collect printed pages |
| You also need to edit text, forms or pages in the same PDF | Install the desktop client from download.omnidoc.top and use the PDF editor on a Windows, macOS or Linux computer | The PDF editor, including sign, is part of the desktop client |
| You are working on translation rather than signing | Use the OmniDoc web version at omnidoc.top | The web version handles document translation, not PDF signing |
Before you start
- Confirm the document is final. If the text changes after you sign, the signature no longer matches what the other party read. Sign the last version only.
- Check that the file opens and can be saved. Some PDFs are locked against editing or need a password. A locked file can stop you from saving a signed copy, so get an unlocked version first.
- Find out what the recipient expects. Some people accept a drawn signature. Others want a typed name, a date, or a specific form. Asking first saves you from resigning.
- Decide where the signature and date go. Look at the signature line and any date field before you start. Placing the mark in the right spot is easier when you know the target area.
- Have a steady way to sign. A finger works, and an Apple Pencil usually gives a cleaner line. Practice once on a blank area so your signature doesn't look cramped.
Adding your signature on an iPad, step by step
- Open the PDF in an iPad app that can view and mark up PDFs. Any viewer with a markup or signature option works for this method. Open the original file, not a copy you have already edited.
- Start the signature tool and draw your signature. Use your finger or Apple Pencil and sign at a natural size. A tiny signature is hard to read once the page is zoomed out.
- Place the signature on the signature line. Drag it into position and resize it so it fits the line without covering printed text.
- Add the date and your printed name if the document asks for them. Many forms expect these next to the mark, and they help the recipient confirm who signed and when.
- Save the result as a new file. Give the signed copy a different name, such as "contract-signed," so the unsigned original stays intact.
- Open the saved copy in a second viewer to confirm it. Some apps show markup that doesn't survive saving in another program. Checking now is faster than finding out after you send it.
If you have a computer and need OmniDoc's own signing tool, install the desktop client from download.omnidoc.top. Open the PDF in the PDF editor and use its sign feature. This route also gives you the other PDF editing options listed in OmniDoc's product information, such as editing paragraph text, filling forms and page operations.
Check the result
Once you have the signed copy, check these items before you send it to anyone.
| Check | How to see it | If it's wrong |
|---|---|---|
| The signature appears on the page | Open the saved copy in a different viewer or on a computer | Sign again and save, then recheck; the mark may not have been saved into the file |
| The signature sits on the signature line | Zoom in on the page and look at the placement | Undo the mark, resize it and drag it so it doesn't cover text |
| The name and date are readable | View the page at full zoom | Retype them in a clearer position or with a larger size |
| The signed copy matches the final text | Compare the page with the version the recipient received | If the text changed, sign the new version from the original file |
| The recipient accepts a drawn signature | Check their instructions or ask them | Send through a sign request or use the desktop sign feature if they need a different form |
Why the browser version isn't the signing route
Readers often expect the web version of a tool to handle everything. In OmniDoc's case, the web version at omnidoc.top is for document translation. Signing a PDF is part of the desktop client's PDF editor. Knowing this up front saves you from searching for a signing button that the product information doesn't describe on the web.
If the signing job is about getting other people to sign, the sign request feature is the better match. It is designed to send a PDF for others to sign online, so you don't need to sign it yourself first.
❓ FAQ
1. Is a drawn signature the same as a digital signature?
Not always. A drawn signature is an image placed on the page, while some workflows call for a signature tied to a verified identity. Ask the recipient which form they require before you sign.
2. Can I sign a scanned PDF on an iPad?
Yes. A scanned page takes a signature the same way a digital page does, because you place the mark on top of the page. If you need the text searchable first, the OCR feature in OmniDoc's desktop PDF editor is one option.
3. Why can't I find the signing tool in the OmniDoc web version?
The web version at omnidoc.top is built for document translation. The PDF signing tool in OmniDoc's product information is part of the desktop client, so use that on a Windows, macOS or Linux computer.
4. Do I have to send the file to someone else to sign it?
No. You can sign your own PDF on the iPad and save a signed copy. Use a sign request only when someone else needs to sign the document.
📝 Summary
To add an electronic signature on an iPad, draw your signature in a PDF markup tool, place it on the signature line, and save a new copy. Use OmniDoc's desktop client for its PDF signing tool, or a sign request when other people need to sign online.
