Need to Scan Your Tax Documents Before Deadline? Use Your iPhone’s Hidden Scanner

You have mere days to finish filing your taxes, but there’s still enough time for you to collect all your documents and file them with a free tax software option (without resorting to an AI chatbot). Yet what if you need to sign and scan physical versions of your tax documents? 

When you just have to put your signature on a sheet of paper but don’t have a standalone scanner handy, the easiest way is right in your pocket: Just use your iPhone — yes, the one in your pocket — to turn images shot on its camera into PDFs.

Yes, your iPhone doubles as a document scanner. It may not produce images as sharp as a dedicated scanner would, but it does a respectable job, even when the phone is positioned at odd angles, trying to capture text. iPhones have had this hidden feature since iOS 11 launched in 2017, but as the cameras built into Apple phones have improved, so has their ability to take decent scans of documents and turn them into PDFs you can email. 

You won’t need to download additional software or pay for a third-party app — Apple’s Notes app, which comes preinstalled on iPhones, does the trick. The good news is that it’s quick and easy to scan a document, save it, and send it wherever it needs to go. If you’ve kept your phone up to date with iOS 26, it’s easy to use this feature. Keep in mind that the process will be different if you haven’t upgraded past iOS 17, but we’ll walk you through it.  

Here’s how to scan a document with your iPhone.

Scan a document with your iPhone or iPad

To scan a document with your iPhone or iPad, first place the document on a flat surface in a well-lit area. 

Open the Notes app and either open an existing note or start a new one by tapping the New Note button in the bottom right corner (pencil-in-square icon). If you’re on iOS 26, tap the Attachments button (the paperclip icon), then tap Scan Documents. On iOS 17 and earlier, instead of the Attachments button, tap the Camera button at the bottom of the screen (or, if you’re editing a note, the same Camera icon above the keyboard), then tap Scan Documents. 

This will open a version of the Camera app that just looks for documents. Once you position your iPhone over the document you want to scan and place it in view of the camera, a yellow rectangular layer will automatically appear over the document, showing approximately what will be captured. Hover over the document for a few seconds, and the iPhone should automatically capture and scan the document, but you can also tap the Shutter button in the bottom center. You can scan multiple documents at once if you’d like. When you’re done, tap the yellow checkmark in the top-right corner. 

Sign, share or save your scanned document

Once you’ve captured a document, you can tap it and any others you’ve captured in the same session to edit them before saving. You can also tap Retake in the top right corner to start again.

When you edit the document, you can recrop it from the original photo (if you need to tweak its edges) and switch between color filters (color, black and white, grayscale or the unedited original photo). Then you can save the scanned document.

Once it’s saved as a note, you can tap the Markup button (circled pen icon) at the bottom to sketch or scribble with different colors. If you tap the Add button at the bottom right (the plus sign icon), you can add text, your signature, shapes or even stickers. Once you’ve added a signature, you can tap it to bring up a menu,  then tap the diagonal line to edit its thickness and color. You can tap and hold the signature to move it around.

There are also AI tools for adding and rewriting text, though they aren’t helpful for signing documents. To use them, tap the center button that looks like a diagonal pencil stylus surrounded by a circle of loops. 

To send or save the document locally, tap the Share button at the top (the square-and-arrow icon) to send it via Messages or other apps, copy it, save it locally in the Files app, or print it via a linked printer or other options.

How to export your scanned document as a PDF

Understandably, you may want to send your scanned document as a PDF. Tap the Share button at the top (the square-and-arrow icon) and scroll down below the contact and app roulettes to the additional list of options. 

The easiest way to send your scanned document as a PDF is a bit convoluted: Among the aforementioned list, tap Print, then tap the Share button at the top (square-and-arrow icon) again — this will share your PDF-converted document. Then pick your share method of choice, most easily via email, though you can also upload it to cloud storage or send it via text message if you want.

You can also use a third-party app to convert your document to PDF if you so choose. Scroll down past the Print button to find your app of choice. For instance, if you have the Adobe Acrobat app downloaded to your device, you can select Convert to PDF in Acrobat to do so — though you’ll need to wade past several screens attempting to upsell you on Adobe subscriptions first. 

Why can’t I find the camera button to scan documents?

If you’re running iOS 26, the Camera button has been replaced by an Attachments button (a paperclip symbol). It should function just the same: Tap it and choose Scan Documents from the dropdown menu

If you can’t see the Camera or the Attachments button, check to see if you’ve opened the note in either the iCloud section or the On My iPhone section — you’ll only be able to scan documents and save them in either of these places. If you can’t tell, tap Folders in the top-left corner of the Notes screen, then select either iCloud or On My iPhone. 

The document scanner is just one of many unnoticed iPhone features that come prepackaged in Apple’s handsets, often nested in the apps that come with your phone. Some hidden iOS 26 features add even more surprising capabilities already on your iPhone. But you can also find ways to do other tasks, like making a GIF on your iPhone, using third-party apps, or doing it in your browser.
