Understanding the Official RRB Guidelines for 2026
Before you upload your images, it is crucial to understand what the Railway Recruitment Board exactly demands. The RRB uses automated software to scan applications, meaning even a slight variation in size, background color, or file format can lead to an instant rejection.
1. Photograph Specifications
Your passport-size photograph is the most critical part of your application. Here are the strict rules you must follow:
- Dimensions: The image must be exactly 240 pixels in width and 320 pixels in height (240x320 px).
- File Size: This is where most students fail. The official requirement mandates that your file size must be strictly between 50 KB and 100 KB. If you need to resize images for other specific limits, you can easily use our 100KB Resizer or 50KB Resizer.
- Background: The background of the photo must be plain white or a very light color. Dark backgrounds or busy sceneries are strictly prohibited.
- Face Coverage: Your face should cover at least 50% of the photograph. You must look directly into the camera with a neutral expression. If your photo needs manual adjustment before formatting, try our Image Cropper.
- Recency: The photograph should not be older than two months from the date of your application.
2. Signature Specifications
Just like the photograph, your signature acts as a primary identification tool throughout the recruitment process, including the Computer Based Test (CBT) and Document Verification (DV).
- Dimensions: The signature must be scanned and cropped to exactly 140 pixels in width and 60 pixels in height (140x60 px).
- File Size: The file size must be strictly between 30 KB and 50 KB.
- Ink Color: You must sign using a Black Ink Pen only. Signatures in blue, red, or any other color will be rejected.
- Writing Style: The signature must be in running handwriting. Block letters or ALL CAPS signatures are considered invalid.
How to Use Our Document Formatting Tool
We understand that manually resizing images and compressing them to specific KB limits is difficult. Follow these simple steps to prepare your documents instantly:
Step 1: Upload Your Photograph
Go to the Photo section of our tool and click on the upload box. Select your raw, unedited passport-size photograph. Our system natively supports formats like JPG, JPEG, and PNG.
Step 2: Adjust and Zoom
Once uploaded, your image will appear inside a preview canvas that is locked to the official 240x320 ratio. Use the slider provided to zoom in or out, then click and drag the image to center your face perfectly.
Step 3: Auto-Compress and Download
As you adjust the image, our background algorithm calculates the optimal compression. Once you are satisfied with the alignment, click the "Download Photo" button. The tool will automatically force the file size to drop exactly within the required 50 to 100 KB limit.
Step 4: Process Your Signature
Scroll down to the signature section. Upload the photo of your signature, adjust it within the 140x60 canvas, and hit download for a perfectly formatted 30-50 KB file.
Top Reasons for RRB Form Rejections
- Blurry Images: If your original photo is of very low quality, compressing it further will make it unrecognizable.
- Selfies: Never upload a selfie. Always use a proper, professionally captured passport photograph.
- Incorrect Ink: Many students mistakenly use a blue pen for the signature. RRB strictly demands black ink.
- Capital Letters: Signing your name in normal block letters (e.g., RAHUL KUMAR) will lead to immediate rejection.
