You don’t need a bulky scanner machine anymore — your phone can scan, edit, and export documents just as well, if not better. This guide breaks down the best scanner apps and built-in tools for iPhone and Android, including Adobe Scan and Microsoft Office Lens, so you can digitize any document and save it as a PDF in seconds.
In past years, employees couldn’t live without a physical scanner. Scanning documents was an essential process for every office worker. But times have changed, and we’re now in an era of modern technology where a smartphone can do the same job, often better. Here are the best alternatives to a traditional scanner machine in 2026.
Use Built-In Phone Scanners First
Before downloading a third-party app, check what your phone already offers. Both iPhone and Android devices now include native document-scanning tools:
- iPhone Notes app: Open Notes, tap the camera icon, and select “Scan Documents.” It automatically detects edges and lets you save as a PDF or image.
- Android Camera/Google Drive: Many Samsung and Google Pixel phones can scan directly from the Camera app. Alternatively, Google Drive has a built-in scanner (covered below).
These built-in options are free, require no extra installation, and are enough for most casual scanning needs.
Best Scanner Machine Apps for Your Phone
Since the days of an ordinary scanner, many applications have appeared that can replace it. Using a phone scanner app lets you process and save documents in different formats. This turns your iPhone or Android into a small mobile office and helps boost productivity using the device already in your hand.
PDF Scanner App
If you want more control over the look of your scanned images, the Scanner App is a strong option. Unlike apps that limit you to preset styles, it lets you fully customize your scans.
The app offers multiple filters and sliders to adjust brightness and contrast down to the percent. Once your image looks right, you can export it as a PDF or as a standalone image file.
Microsoft Office Lens
Microsoft Office Lens integrates directly with the Microsoft Office Suite, making it a great choice if you already rely on Word, Excel, or OneNote.
The app works like most scanning tools: you capture an image, clean it up, and export it. It includes automatic boundary detection and several scanning modes. You can save scans as an image or PDF, and one of its biggest advantages is the ability to save scans directly in Microsoft Office format.
Adobe Scan
Adobe Scan remains one of the highest-rated free scanning apps available in 2026, thanks to its accuracy and built-in OCR (text recognition). It requires a free Adobe account but has no cost to use.
Setup takes just a few minutes. The app automatically detects the edges of a document, and you can manually adjust them if it makes a mistake. It also includes specialised modes like “whiteboard” and “book” for different scanning needs.
After capturing an image, you can extract text directly from it and copy it to your clipboard, or export the file as a PDF or JPEG.

Google Drive
Google Drive includes a lesser-known but genuinely useful document-scanning feature. To use it, open the Google Drive app on your iPhone or Android, tap the plus icon in the bottom right, and select the scan option from the menu.
Unlike other apps on this list, Google Drive’s scanner doesn’t show live boundary detection while you’re taking the photo — you only see the result afterwards. This means occasional scans may come out with slightly uneven borders, so it’s worth double-checking the image before saving. Once you’re happy with the result, you can save it as an image or PDF directly to your Google Drive.
Which Scanner Machine Alternative Should You Choose?
Summing Up
Today, you can scan documents using a scanner app, a built-in phone tool, or even just your camera — you don’t need to hunt down a standalone scanner machine. Every app covered here is free or offers a free tier, and each is easy to set up in minutes.
Whether you’re an office employee, a student, or someone who just needs to send a scan to a friend or relative, there’s no need to search for an old-fashioned scanner. Pick the app that fits your workflow best and start scanning directly from your phone.
