What is the Image Resizer Tool?
The KagazKit Image Resizer is a specialized utility designed to resize and compress photographs to meet the strict dimensional and file size requirements demanded by Indian government exam portals and official document submissions. Government portals for UPSC, SSC, IBPS, Railway, and other competitive exams require photos in very specific pixel dimensions (e.g., 200×230 or 350×350 pixels) and strict file size ranges (typically 20KB to 50KB). Manually achieving this with generic photo editors is frustrating and error-prone. Our tool automates the entire process with a smart binary-search compression algorithm that finds the perfect JPEG quality level to hit your target KB range.
How to Use This Tool
- 1Select a preset format — Choose from UPSC, SSC, IBPS presets or set custom dimensions and KB limits for your specific portal.
- 2Upload your photo — Click the upload area or drag-and-drop your passport-size photo. Supports JPG, PNG, and WebP formats up to 10MB.
- 3Click "Resize & Compress" — The tool resizes your image to the exact pixel dimensions and uses an iterative compression algorithm to fit within the target KB range.
- 4Download the result — Review the final file size shown on screen, then click "Download Image" to save the compliant file to your device.

Frequently Asked Questions
Will my photo be saved on your servers?
No. This tool runs 100% locally in your web browser using client-side JavaScript. Your photo never leaves your device — it is processed entirely in memory using the HTML5 Canvas API. No data is uploaded, stored, or transmitted to any server.
Why does the image quality change after compression?
To fit strict government limits (like 20-50KB), the tool compresses the image by adjusting its JPEG quality level and resizing its dimensions. We use a binary search algorithm that iteratively tests different quality values to find the best possible quality that still fits under the maximum KB limit — maximizing clarity while meeting requirements.
What image formats are supported?
You can upload JPG, PNG, or WebP images. For JPG input, the tool outputs a compressed JPG. For PNG input, it preserves the PNG format to maintain transparency. The final downloaded file is compatible with all government portals.
What if the output file is still too large or too small?
If the output doesn't hit the exact target range, try uploading a smaller or larger original image. The compression algorithm works best when the original image is reasonably sized — very large originals (5000+ pixels) may compress differently than standard passport photos.
Can I use this tool offline?
Yes! Since the entire tool runs in your browser with no server dependency, it works even without an internet connection after the page has loaded. This makes it perfect for use in exam centers or areas with poor connectivity.
