When scanning documents or images, you might encounter an issue called bleedthrough. This happens when the text or images from the reverse side of the paper show through on your scanned file, reducing its clarity and quality. Luckily, with a versatile and lightweight tool like IrfanView, you can easily remove bleedthrough and enhance the quality of your scanned documents.
In this article, we’ll explore how to remove bleedthrough in IrfanView step by step, ensuring you achieve clear and professional results.
What is Bleedthrough in Scanned Images?
Bleedthrough occurs when the content on the opposite side of a document is visible in your scanned image. This problem is common with:
- Thin or low-quality paper.
- Double-sided printed documents.

Step-by-Step Guide to Remove Bleedthrough in IrfanView
Follow these simple steps to remove bleedthrough in IrfanView:
Step 1: Open the Image in IrfanView
- Launch IrfanView on your computer.
- Go to File > Open and select the scanned image you want to edit.
Step 2: Convert to Grayscale (Optional)
If your document doesn’t require color, converting to grayscale can simplify the process of reducing bleedthrough.
- Go to Image > Convert to Grayscale.
- This removes all color information, leaving you with a black-and-white image.
Step 3: Adjust Brightness and Contrast
Brightness and contrast adjustments can help fade out the unwanted bleedthrough areas.
- Go to Image > Color Corrections.
- Increase the Brightness slider slightly to brighten the image.
- Adjust the Contrast slider to make the main content more prominent.
- Click OK to apply the changes.
Step 4: Use Gamma Correction
Gamma correction helps balance light and dark areas of the image.
- In the same Color Corrections dialog, tweak the Gamma Correction slider.
- Increase or decrease the value until the bleedthrough fades without affecting the main content.
Step 5: Apply Filters
Filters can smooth out the image and reduce visible bleedthrough.
- Go to Image > Effects > Effects Browser.
- Try using the Blur or Median filter to soften the unwanted background.
- Preview the changes and apply the filter that works best.
Step 6: Reduce Noise
Bleedthrough often appears as speckled noise. Use IrfanView’s noise reduction feature to clean it up.
- Go to Image > Effects > Reduce Noise.
- Apply the effect and adjust settings as needed.
Step 7: Enhance Text or Main Content
To ensure the text or primary content stands out, apply slight sharpening.
- Go to Image > Effects > Sharpen.
- Apply a small amount of sharpening to enhance clarity.
Step 8: Save the Edited Image
Once you’re satisfied with the adjustments:
- Go to File > Save As.
- Save the image in your preferred forma.
