As a content creator for carcodepro.com and an automotive repair expert, I understand the importance of efficient digital processes. While my usual focus is on vehicles, the need to manage digital documents effectively crosses all professions. Many online platforms, especially government portals like SSCASN for civil service applications, require document uploads with strict file size limits. One common requirement is uploading scanned documents, such as ID cards, in JPG format with a maximum size, often 200 KB. This article will guide you through various methods to reduce the file size of your scanned JPG documents, ensuring they meet these requirements without sacrificing essential information.
Why Reduce JPG Size of Scanned Documents?
Before diving into the methods, it’s crucial to understand why reducing the size of scanned JPG files is necessary. Large image files consume significant storage space, take longer to upload and download, and can slow down website loading times. For platforms like SSCASN, which handle a massive volume of applications, file size restrictions are implemented to optimize server performance and ensure a smooth application process for everyone.
Specifically, scanned documents, especially those scanned at high resolutions, can result in large JPG files. Reducing the file size makes these documents:
- Easier to Upload: Faster upload times, especially on slower internet connections, are crucial when application deadlines are tight.
- Compliant with Platform Requirements: Avoid application rejections due to oversized file uploads.
- Efficient to Store and Share: Smaller files are easier to manage, store on devices with limited space, and share via email or messaging apps.
Methods to Reduce JPG Scan File Size
Fortunately, reducing the file size of JPG scans is a straightforward process. Several tools and techniques are available, catering to different user preferences and technical skills. Here are four popular methods:
1. Using Online JPG Compression Tools (iLoveIMG, Compress JPEG)
Online JPG compressors are web-based applications that allow you to reduce file size directly in your browser, without needing to install any software. They are convenient, user-friendly, and often free. Two excellent options are iLoveIMG and Compress JPEG.
Using iLoveIMG:
- Open your web browser and navigate to iLoveIMG.
- Click the “Select images” button.
- Choose the JPG scan file you want to compress from your computer and click “Open”.
- iLoveIMG offers different compression levels. The default setting usually provides a good balance between file size reduction and image quality. For more control, you can explore the “Compress Level” options.
- Click the “Compress IMAGES” button.
- Once the compression is complete, click “Download compressed images” to save the reduced file size JPG to your computer.
Using Compress JPEG:
- Open your web browser and go to Compress JPEG.
- Click the “UPLOAD FILES” button.
- Select the JPG scan file from your device and click “Open”.
- Compress JPEG automatically starts compressing the image. You can adjust the compression quality using the slider if needed.
- After compression, click the “DOWNLOAD” button to save the smaller JPG file.

2. Using Mobile Apps (Compress Image Size)
For users who prefer to work on their smartphones or tablets, mobile apps provide a convenient way to compress JPG scans directly on their devices. “Compress Image Size” is a popular app available on Android’s Play Store.
Using Compress Image Size:
- Download and install “Compress Image Size” from the Google Play Store.
- Open the app and tap the “Gallery” icon to select the JPG scan you want to compress.
- The app displays the original file size. Use the “Quality” slider to adjust the compression level. Lower quality means smaller file size but potentially reduced image detail.
- Tap the “Compress” button.
- The app will process the image and display the compressed file size. You can then save the compressed JPG to your phone’s storage.

3. Using Desktop Software (Paint – Windows)
If you prefer using desktop software and are a Windows user, the built-in Paint application offers a simple method to resize and reduce the file size of JPG scans.
Using Paint (Windows):
- Open the Paint application on your Windows computer.
- Click “File” in the top left corner, then select “Open”.
- Browse to the location of your JPG scan file, select it, and click “Open”.
- On the “Home” tab, click the “Resize” button.
- In the “Resize and Skew” dialog box, select “Pixels”.
- Reduce the “Horizontal” and “Vertical” pixel values. Reducing the pixel dimensions directly reduces the file size. Experiment with smaller values to achieve the desired file size while maintaining acceptable image quality. Ensure “Maintain aspect ratio” is checked to avoid distorting the image.
- Click “OK”.
- Click “File”, then “Save As”. Choose “JPEG picture” as the file type.
- Select a save location and file name, and click “Save”.

Best Practices for Scanning Documents for File Size Optimization
While these compression methods are effective, you can also proactively minimize file size during the scanning process itself:
- Choose the Right Resolution: Scan at a resolution that is sufficient for readability but not unnecessarily high. For documents like ID cards, a resolution of 200-300 DPI (dots per inch) is usually adequate. Higher resolutions result in larger files.
- Select JPG Format: JPG is a lossy compression format, meaning it reduces file size by discarding some image data. However, for documents, the quality loss at moderate compression levels is usually negligible. Avoid lossless formats like PNG or TIFF if file size is a concern.
- Scan in Color Only When Necessary: Color scans generally produce larger files than grayscale or black and white scans. If color is not essential for the document’s purpose, scan in grayscale or black and white to reduce file size.
- Crop Unnecessary White Space: Before saving the scan, crop out any excessive white space around the document. This reduces the amount of data the JPG compression needs to process, resulting in a smaller file.
Conclusion
Reducing the file size of scanned JPG documents is a vital skill for anyone needing to upload documents online, especially for applications with file size restrictions. By utilizing online tools like iLoveIMG and Compress JPEG, mobile apps like Compress Image Size, or desktop software like Windows Paint, you can easily optimize your scanned documents. Remember to also implement best practices during the scanning process itself to minimize file size from the outset. Mastering these techniques ensures your documents are not only compliant with platform requirements but also efficient to manage and share.
