Custom Photo & Signature Resizer
Set custom dimensions, crop ratios, and strict KB file size limits for any central or state government recruitment portal (UPSC, SSC, Railway RRB, Post Office, and State PSCs).
Why Use a Custom Image Resizer for Government Applications?
While many major examinations in Tamil Nadu (like TNPSC and TNUSRB) use standard photo configurations, several other recruitment boards require highly specific, non-standard dimensions. For instance, the **Union Public Service Commission (UPSC)**, **Railway Recruitment Boards (RRB)**, **India Post (GDS)**, and various public sector banks enforce their own unique pixel boundaries, aspect ratios, and file-size brackets.
Attempting to resize these documents with standard phone editors often results in distorted aspect ratios, stretched faces, or blurry details. Our Custom Image Resizer gives you granular, pixel-perfect control. You can manually enter dimensions in **pixels, centimeters, or inches**, configure exact target file size limits in kilobytes (KB), and maintain high visual clarity.
DPI to Pixels Conversion Guide for Exam Portals
Many exam notifications specify dimensions in centimeters or inches alongside a required DPI (Dots Per Inch) value. Use this quick reference table to input the correct pixel equivalent:
| Dimensions Required | DPI Specification | Pixel Equivalent (Width x Height) | Typical Use Cases |
|---|---|---|---|
| 3.5 cm x 4.5 cm | 200 DPI | 276 x 354 pixels | UPSC / Central Govt Portals |
| 3.5 cm x 4.5 cm | 300 DPI | 413 x 531 pixels | High Resolution Submissions |
| 4.5 cm x 3.5 cm | 200 DPI | 354 x 276 pixels | IBPS / Bank Exam Photos |
| 3.5 cm x 1.5 cm | 200 DPI | 276 x 118 pixels | Standard Exam Signatures |
| 3.0 cm x 3.0 cm | 200 DPI | 236 x 236 pixels | Left Thumb Impressions |
How to Customize Your Images
Read Official Notification
Always open the recruitment board's PDF notification and verify target units (cm, inches, or px) and file limits.
Input Custom Parameters
Enter your custom width and height in the editor panel. Lock the aspect ratio if you wish to prevent facial distortion.
Align Crop Rectangle
Drag and scale the crop handles to center the candidate's eyes, forehead, and shoulders horizontally.
Fine-Tune File Weight
Move the quality slider or set a strict maximum target KB (e.g. 50KB or 100KB) to ensure automatic portal acceptance.
Client-Side Compression
All conversion algorithms run locally inside your browser's memory. Your personal documents are never uploaded to our servers.
Frequently Asked Questions
Q. What is the difference between pixels, cm, and inches in exam photos?
Pixels represent the digital resolution on screen, whereas centimeters and inches measure the physical printed size on your hall ticket. Our tool converts metrics accurately depending on your input.
Q. How do I configure my photo for UPSC applications?
UPSC typically requires photos to be 3.5 cm x 4.5 cm with file size between 20 KB and 300 KB. Select centimeters as your unit, input 3.5 width and 4.5 height, and set the target limit to 300 KB.
Q. What color ink should be used for custom signatures?
Unless specified otherwise, write your signature using a black ink ballpoint pen on plain, white unruled paper. This provides the best scanner contrast for digital indexing.
Q. What are the rules for handwritten declarations?
For bank applications (IBPS/SBI), the self-declaration text must be written in your own handwriting in English, strictly using black ink, and must not be in capital letters. Target file size is 50-100KB.
Q. Can I upload PNG files to recruitment portals?
No. Nearly all state and central portals strictly restrict uploads to JPEG/JPG formats. Our custom editor automatically converts PNG or WebP files to JPG when you download.
Q. Why do government portals fail to upload standard photos?
Many government systems use legacy server-side verification scripts. If a file's header, resolution, or KB size is even slightly outside of the required values, the server blocks it. Our tool cleans and aligns headers for maximum compatibility.
Q. What are the rules for left thumb impressions?
The thumb impression must be clear, showing distinct ridges, made in blue or black ink on white paper. The standard resolution is 3 cm x 3 cm (240 x 240 pixels) with a size between 20 KB and 50 KB.
Q. Are my uploaded files saved anywhere?
No. We prioritize your privacy. All crop, resize, and quality modifications are executed locally in your browser memory. No data is stored, tracked, or sent online.
How to use the Custom Photo Resizer

Pro Tips for Custom Success
Common Rejection Mistakes to Avoid
Distorted Aspect Ratio
Manually entering dimensions that do not match your original image's ratio and forgetting to center the crop properly, resulting in a squashed face.
Entering Wrong Metric Units
Confusing centimeters and inches. Always double check if your exam notification asks for centimeters (cm) or inches.
Using Low Resolution Sources
Uploading a small thumbnail image and trying to upscale it. Always upload the original high-resolution photo.

Frequently Asked Questions about Custom Photos
Q.How do I calculate dimensions from cm to pixels?
Our custom resizer does this automatically! Simply select 'cm' or 'inches' as your unit, input the dimensions, and the tool translates it to pixel values dynamically.
Q.Why is the target KB limit not exactly met?
Image compression depends on the complexity of colors in the photo. Our tool uses iterative optimization to get as close as possible to the target size without exceeding it.
Why use our Custom Resizer?
For exams not covered by our standard templates, the Custom Editor gives you complete control over dimensions, aspect ratios, and file sizes. This utility runs entirely inside your browser, ensuring 100% data safety.
