In today’s digital world, scanning documents and images is a common practice. Whether you’re digitizing old photos, important documents, or car part diagrams for your repair website, you often end up with JPEG files. Sometimes, you might need to increase the JPEG file size of a scan. This could be for various reasons, such as needing a higher resolution image for printing, improving image quality for detailed viewing, or meeting specific file size requirements for online platforms that surprisingly demand larger files.
While the original Indonesian article focused on reducing file size for ID card submissions, we’ll flip the script and guide you on how to enlarge your scanned JPEG files. We’ll explore several methods, from online tools to desktop applications, ensuring you can effectively increase the size of your JPEG scans without compromising quality too much.
Why Increase JPEG File Size?
Before diving into the methods, let’s understand why you might need to increase the file size of a JPEG scan:
- Improved Print Quality: Larger file sizes generally mean more data, which translates to higher resolution and better print quality, especially for larger prints.
- Enhanced Detail: For images with intricate details, like diagrams or schematics, increasing the file size can help reveal finer details when zoomed in.
- Specific Platform Requirements: Although less common, some online platforms or applications might have minimum file size requirements, necessitating an increase in size.
- Perceived Quality Improvement (Sometimes): In certain cases, upscaling an image can subjectively improve its appearance on larger screens, even if it doesn’t add actual detail.
However, it’s crucial to understand that simply increasing file size doesn’t magically enhance image quality. Upscaling, the process of increasing image dimensions, can sometimes lead to pixelation or blurriness if not done correctly. We’ll address how to minimize these issues.
Methods to Increase JPEG File Size
Here are several methods to increase the JPEG file size of your scans, drawing inspiration from the tools mentioned in the original article, but adapting their use for enlargement:
1. Using Online Tools: iLoveIMG (Resize Image Feature)
iLoveIMG, mentioned in the original article for compression, also offers a robust Resize Image feature that can be used to increase file size by enlarging the image dimensions.
Steps:
- Visit iLoveIMG: Go to the iLoveIMG website in your browser.
- Select ‘Resize Image’: Find and click on the “Resize Image” tool.
- Upload Your JPEG Scan: Click the “Select images” button and upload the JPEG scan you want to enlarge.
- Choose Resize Options:
- By Pixels: Select “By Pixels” and enter larger pixel dimensions for width and height than your original image. Increasing pixel values will increase the file size.
- By Percentage: Alternatively, choose “By Percentage” and enter a percentage greater than 100% (e.g., 150%, 200%) to enlarge the image proportionally.
- Resize Image: Click the “Resize Images” button.
- Download: Once processed, click “Download resized images” to save the enlarged JPEG file.

Note: While iLoveIMG is convenient, be mindful of over-enlarging, which can lead to noticeable quality loss. Start with smaller percentage increases and check the results.
2. Using Online Tools: Online Image Resizer (Various Options)
Numerous other online image resizers can help increase JPEG file size. Websites like “ResizePixel,” “Birme,” or “ImageResizer” offer similar functionalities to iLoveIMG’s resize tool. Simply search for “online image resizer” to find various options.
General Steps (similar across most online resizers):
- Go to an Online Image Resizer Website: Choose a website from your search results.
- Upload Your JPEG: Look for an “Upload” or “Select Image” button and upload your scanned JPEG file.
- Resize Settings:
- Enter New Dimensions: Input larger width and height values in pixels or centimeters/inches.
- Percentage Scaling: Use a percentage value above 100% to scale up the image.
- Maintain Aspect Ratio: Ensure the “Maintain aspect ratio” option is checked to prevent distortion.
- Resize and Download: Click the “Resize,” “Enlarge,” or similar button to process the image. Download the enlarged JPEG file.

Tip: Explore different online resizers to find one with a user interface and features you prefer. Some might offer more advanced resizing algorithms.
3. Using Desktop Software: Paint (Windows)
As mentioned in the original article for compression, Paint, the built-in image editor in Windows, can also be used to increase JPEG file size by resizing the image.
Steps:
- Open Paint: Search for “Paint” in the Windows search bar and open the application.
- Open Your Scan: Click “File” > “Open” and locate and open your JPEG scan file.
- Resize: On the “Home” tab, click the “Resize” button.
- Resize by Pixels or Percentage: Choose either “Pixels” or “Percentage.”
- Pixels: Select “Pixels” and enter larger horizontal and vertical pixel values.
- Percentage: Select “Percentage” and enter values greater than 100% for horizontal and vertical.
- Maintain Aspect Ratio: Ensure “Maintain aspect ratio” is checked.
- Click “OK”: Click “OK” to apply the resize.
- Save As JPEG: Click “File” > “Save As” > “JPEG picture.” Choose a location and filename and click “Save.”

Limitations of Paint: Paint offers basic resizing but lacks advanced upscaling algorithms found in more sophisticated image editing software. For significant enlargements, quality loss might be more noticeable.
4. Using Advanced Software: GIMP or Adobe Photoshop
For more control and potentially better results when increasing JPEG file size, consider using advanced image editing software like GIMP (free and open-source) or Adobe Photoshop (paid). These programs offer more sophisticated resizing algorithms that can minimize quality degradation during upscaling.
General Steps (GIMP – similar in Photoshop):
- Download and Install GIMP: If you don’t have it, download and install GIMP from www.gimp.org.
- Open Your Scan in GIMP: Open GIMP and go to “File” > “Open” to open your JPEG scan.
- Scale Image: Go to “Image” > “Scale Image.”
- Enter New Dimensions: In the “Scale Image” dialog:
- Width and Height: Enter your desired larger width and height in pixels.
- Quality/Interpolation: This is crucial for quality. Experiment with different “Interpolation” methods. “Lanczos” or “Cubic” are generally good choices for upscaling as they tend to produce smoother results with less pixelation compared to “Linear” or “Nearest Neighbor.”
- Click “Scale”: Click the “Scale” button.
- Export as JPEG: Go to “File” > “Export As.” Choose a filename and ensure the file extension is “.jpg” or “.jpeg.” Click “Export.” You can adjust JPEG quality settings during export, but for increased size, these are less critical than the resizing process itself.

Benefits of Advanced Software:
- Superior Upscaling Algorithms: GIMP and Photoshop offer more advanced interpolation methods (like Lanczos, Bicubic Smoother, etc.) that can produce better-looking upscaled images with reduced pixelation and blur.
- More Control: These programs provide finer control over the resizing process and offer tools for further enhancing image sharpness after upscaling.
Important Considerations for Increasing JPEG File Size:
- Quality Loss is Inevitable (to some extent): Remember that upscaling inherently involves adding pixels that weren’t originally there. While good algorithms minimize quality loss, some degradation is usually unavoidable, especially with significant enlargements.
- Don’t Overdo It: Avoid excessively increasing the size. Gradual increases with quality checks are better than drastic enlargements that result in blurry or pixelated images.
- Check File Size: After resizing, always check the new file size to ensure it meets your requirements. File size increase is related to dimension increase, but also influenced by image content and JPEG compression levels (which are less relevant when you are just resizing).
- Original Scan Quality Matters: The quality of your original scan greatly impacts the results of upscaling. A blurry or low-resolution scan will not magically become high-quality when enlarged.
Conclusion
Increasing the JPEG file size of a scan is achievable using various online tools and desktop software. Whether you opt for the convenience of online resizers like iLoveIMG or the advanced capabilities of software like GIMP or Photoshop, understanding the process and potential quality implications is key. Choose the method that best suits your needs and technical skills, and always aim for a balance between increased file size and acceptable image quality. By following these guidelines, you can effectively enlarge your scanned JPEG files for printing, improved viewing, or any other purpose you may have.
