Sharpen Text Images: How to Make Text More Legible

Ryan Barnett · January 2, 2025

 

Blurry text is enough to cause a lack of professionalism and satisfaction whether you're trying to read a scanned document, see text in photos, or want to make those pesky online posts easier to read. Luckily, tools and techniques for sharpening text have progressed to make that easy and convenient.

Restoring the clarity can be the job of the insMind Unblur Text Image tool, as well as Photoshop and others if you're a professional working on critical documents, or a regular user struggling with readability. In this guide, we'll look at some of the more common reasons for text to blur, tried and tested ways to sharpen images of text, and ways to present crisper text images.

Part 1: Blurry Text Images common issues

There are many reasons why your images can develop blurry text, and none of them help with legibility. The first step in solving this problem is understanding these causes.

· Scans or Photos of low-resolution

Pixelation forms when low-resolution images are scanned or captured in low resolution, resulting in stretched pixels when they are magnified to at least 300% of normal size and they become not readable text. Saving storage costs always comes at the cost of quality, as low-resolution settings are used so frequently to reduce the file size.

· Compression Artifacts

Images can in fact suffer from compression artifacts when you save them in compressed file formats like JPEG. The distortions it produces cause the image to become 'blurry' and look very unprofessional with noise at the text edges.

· Poor Lighting or Camera Focus

The problem with unfocused shots is that you don’t know whether it was caused by inadequate lighting or shaky hands. Clear text is impossible to get without proper stabilization or at least enough brightness, resulting in blurry output.

· Incorrect settings during capture.

Poor image quality caused by poor text can be due not only to subject movement but rather to using wrong settings such as setting a high shutter speed or improper ISO level.

Impact of Blurry Text

The blurry text in the image can have a negative impact in multiple ways including the following:

· Difficulty in Reading

Text that’s blurry strains the eyes as it makes reading difficult; and more so for people with visual impairments. In some cases that can be critical, misunderstandings can result from misinterpreting unclear words.

· Reduced Professionalism

Blurry text shared or presented in business settings will undermine credibility. Professional and detailed presentation is achieved by providing clear, sharp images.

· Decreased Accessibility

Unreadable text prohibits users from effectively accessing key information and can have negative impacts on important things like schoolwork and legal documents.

All of these share one thing in common — if you address them using proper tools and methods you can be sure that the text in your images will always be clear and readable.

Part 4: Capturing Clear Text Images: Tips and Best Practices

It's better to prevent your text images from being obscured than to start editing them. To get high-quality text images captured, follow these tips.

Tips for Scanning Text

· Make sure that you set the scanner to at least 300 DPI of sharp and detailed text scans.

· Be sure the document sits flat on the scanner bed to cut out tilted or skewed images.

· Some dust or smudges on the scanner glass can create clarity problems. Scanning while it's still a bit dirty can ruin it and not make good archival material.

Tips for Photographing Text

· Rely on the tripod or hold your hands on a stable surface to avoid motion blur.

· Put the document in well-lit areas. Don't rely on the natural light source only and always have backup with studio lighting.

· To get crisp details reduce ISO, shutter speed, and aperture. To reduce noise, lower your ISO; to avoid blur, take your shutter speed as fast as it can go.

Editing as the Final Step

· No matter what you’re trying to capture, minor lessons apply. Try the insMind Image Brightener and AI Expand Image tools to blow blurry text out and improve the brightness.

· insMind Cleanup Pictures is a tool that can remove unwanted marks or artifacts around the text.

· Before using or sharing the image review the clarity of your text.

With good editing tools, you can combine these practices to produce text images that are always sharp, professional text images.
