Why You Need to Increase Image Size in KB
While most online tools focus on reducing file size, certain government, university or job application portals have strict minimum file size requirements (e.g., "Photo must be at least 100KB"). Our specialized Photo Size Increaser solves this problem by carefully adjusting the image quality and dimensions to meet this lower bound without causing noticeable distortion. It's the perfect way to get your file over 100KB, 200KB, or any other minimum threshold.
How We Increase the File Size (KB)
-
Maximized JPEG Quality: The primary method is to re-save the image with a 100% JPEG quality setting, which introduces less compression and thus results in a larger file size (more KB/MB).
-
Intelligent Upscaling: If maximizing quality isn't enough to hit your target, the tool will slightly increase the image's pixel dimensions (e.g., by 5-10%). This process is repeated until the minimum KB threshold is met.
-
Client-Side Processing: Like all our tools, the process happens directly in your browser. This means maximum speed, no server upload time, and guaranteed privacy for your files.
Frequently Asked Questions
How can an image size be increased in KB?
Image file size (in KB/MB) is primarily determined by two factors: Compression (JPEG quality) and Pixel Dimensions. To increase the size, the tool first reduces compression (increases quality to 100%). If the target is still not met, it increases the pixel dimensions, making the file larger.
Will increasing the KB size reduce the image quality?
No. Since the tool prioritizes increasing the JPEG quality and only slightly upscales if necessary, the visual quality of the image will generally either remain the same or slightly improve due to less compression. The primary purpose is to meet the file size requirement while maintaining a good appearance.
What is the maximum KB size I can target?
The tool can effectively target file sizes up to a few MB (megabytes). Since file size increases rapidly with upscaling, and client-side processing has memory limits, it works best for targets in the 100KB to 2MB range. For very large targets, you may need a server-side solution or simply upscale the image dimensions manually first.
