Documents don’t always scan perfectly. Edges can get cut off, corners may appear folded or obscured, and staples can leave unwanted marks. These small flaws can make scans look unprofessional or incomplete, leaving you frustrated and spending extra time correcting them. Luckily, there’s an easy way to fix cropped edges with no effort.
“I think I’m in some sort of hell.” That’s how one Reddit user described their feelings after discovering that their flatbed scanner was consistently cropping the edges of scanned documents.
In fact, this issue is surprisingly common and isn’t limited to office scanners only.
Yes, some office scanners can crop several millimeters off the edges, even when the document is placed exactly inside the frame. The reasons can be different, including improperly working software or incorrect calibration. And when you’re scanning dozens of documents, it can become really frustrating.
At the same time, that’s not the only edge-related issue you might run into. Stapled documents create an even more common problem. The thing is, to get a clean scan, you have to remove the staples, sometimes spending ages trying to dig them out with a knife or needle (and that’s not fun at all). Alternatively, you can try folding and scanning each stapled page individually or cutting off the stapled edge with scissors.
Either way, you’ll be left with one side of your scan cropped, which will turn your perfectly rectangular document into something more like a pentagon. The result looks messy and unprofessional, and it may even cut off table borders or notes near the margins.
Fortunately, there’s one solution for both issues. The iScanner app combines all the features of a mobile scanner and PDF editor, making it a universal tool for your document management wherever you are.
Let’s start with the issue of stapled documents, as it’s the most common. iScanner’s new Edge Repair feature fixes it without any struggle with stationery.
This feature uses an on-device neural network to detect and fix imperfections around the corners of your documents, whether they’re folded, obscured by fingers or objects, stapled, or slightly turned. It intelligently reconstructs missing or damaged areas pixel by pixel, delivering a clean, complete scan every time. Trained on over 100,000 images, the model ensures your documents always look sharp and professional, no matter the condition they’re captured in.
Make a clean scan in just three steps:
The restored edge will perfectly match the rest of the page, ready to be shared straight away from the app.
Tip: There’s no need to scan each page separately or fix cropped edges one by one. After selecting Camera, simply take photos of all your document pages. Then, you can restore the edges by switching between pages on the same screen.
iScanner also tackles the common problem of scanners cropping document edges. The app has been using artificial intelligence for years, offering features like Scan Straightener, Background Remover, Image Unblurrer, Name Generator, and Translator.
One of its most powerful AI tools is the document border detection feature. Since its release in 2019, this feature has quickly become one of the favorites among users. It automatically and precisely detects the edges of your document the moment you start scanning, ensuring that nothing important gets cut off. Those missing millimeters of your document will never be a problem again.
If you’ve managed to remove staples from your documents and don’t need to restore the edges, there’s still one thing to take care of. Removing staples often leaves small holes on the paper, which can be visible in your scans. To get rid of them, use iScanner’s Hide feature. Here’s how:
