How it works
Choose a preset or enter dimensions
Pick SSC, passport, signature, or type a custom width and height.

Download the exact-dimension result and check the file size if your form also sets a KB rule.
Frequently asked questions
How do I know if I need to fix my photo dimensions?
If an upload portal gives you an error specifically mentioning 'Width must be X pixels' or 'Invalid resolution', your image dimensions are incorrect. This tool allows you to manually override the width and height to strictly match their requirements.
What is the difference between Contain, Cover, and Stretch?
Contain shrinks the image until the whole thing is visible, leaving blank borders. Cover fills the target box completely, cropping off excess edges. Stretch forces the image to fill the box without cropping, which can artificially warp or distort the subject.
Does changing the dimensions alter my file size?
Yes, reducing the pixel dimensions (downscaling) generally reduces the file size. However, to hit a very specific file size like 'under 20KB', you will still need a dedicated KB compressor as a follow-up step.
Are dimensions and aspect ratio the same thing?
No. Aspect ratio is the proportional relationship between width and height (like 4:3 or 16:9). Dimensions refer to the absolute number of pixels (like 800x600). Application portals usually require exact pixel dimensions, not just an aspect ratio.
Complete Guide to Photo Dimension Fixer for Competitive Exams
When applying for competitive exams, university admissions, or government identification portals, uploading a photograph or signature with incorrect pixel dimensions is one of the most frequent causes of form rejection. Upload portals enforce strict geometric constraints defined in pixels (width x height)-such as exactly 200 x 230 pixels for candidate photographs or 140 x 60 pixels for digital signatures. While visual desktop tools let you scale images arbitrarily, recruitment portals require exact pixel boundaries verified during automated form validation.
Our Photo Dimension Fixer uses precision HTML5 Canvas rendering to export your photograph to the exact width and height mandated by any exam notification. By giving you explicit control over aspect ratio handling-through Contain, Cover, or Stretch modes-you ensure your subject remains crisp, proportional, and compliant with portal validation scripts.
Quick Solution (TL;DR)
To fix an "Invalid Dimensions" or "Wrong Resolution" upload error instantly: enter your required target width and target height in pixels (or select an official exam preset), pick your preferred fit mode (use Cover to crop excess edges cleanly without distortion), and export your image. Your downloaded photograph will match the exact pixel grid required by the portal.
When Should I Use This Tool? (Exam-Specific Use Cases)
Major Indian recruitment boards and public service commissions define precise pixel rules that must be followed without deviation:
- SSC (Staff Selection Commission - CGL, CHSL, MTS, GD): Requires candidate photographs to be formatted to 200 x 230 pixels (approx. 3.5 cm x 4.5 cm proportion) and signatures to 140 x 60 pixels. Using arbitrary image sizes causes the SSC portal to return an "Image Dimensions Mismatch" error.
- IBPS (Banking PO, Clerk, RRB, SO): Mandates passport photograph uploads at 200 x 230 pixels and candidate signatures at 140 x 60 pixels. Automated IBPS verification scripts immediately flag and reject images that differ by even a single pixel.
- UPSC (Civil Services CSE, NDA, CDS, CAPF): Online application forms require square or standard portrait dimensions ranging between 350 x 350 pixels minimum and 1000 x 1000 pixels maximum, or exactly 413 x 531 pixels for standard passport proportions at 300 DPI.
- Railway Recruitment Board (RRB NTPC, ALP, Group D): Demands standardized 200 x 230 pixel photographs so candidate faces align uniformly across digital admit cards and biometric attendance records.
- State PSCs & Entrance Exams (TSPSC, APPSC, NEET, JEE Main): Require strict adherence to specified width and height ratios to prevent distortion on examination admit cards.
Examples: Before & After Scenarios
Before (Rejected by SSC Portal): An applicant uploads an unedited 4000 x 3000 pixel portrait taken from a smartphone. The portal rejects the file with the prompt: "Error: Photograph dimensions must be exactly 200 px width and 230 px height."
After (Accepted on First Attempt): The applicant opens the Photo Dimension Fixer, selects 200 px width and 230 px height with Cover fit mode. The tool cleanly centers the face and outputs a 200 x 230 pixel JPEG. The portal validates the upload immediately.
Troubleshooting Common Upload Rejections
- Subject looks stretched or squished: If you force an image with a wide landscape ratio into a portrait box using "Stretch" mode, the face will warp. Switch the fit mode to Cover (which trims edges while maintaining true proportions) or use our Passport Photo Cropper first.
- Swapped width and height: Always double-check orientation. Entering 230 width x 200 height instead of 200 width x 230 height creates a horizontal image that fails vertical portrait checks.
- Dimensions correct but file size too large: Changing pixel dimensions reduces overall file weight, but if your form also enforces a strict KB ceiling (e.g., between 20 KB and 50 KB), process the resized photo through our Exact KB Compressor.
Best Practices for Photo Resizing
- Crop out unnecessary background clutter before applying exact pixel dimensions so your face occupies 70% to 80% of the frame.
- Prefer Cover over Stretch to ensure natural facial proportions are preserved for facial recognition systems.
- Always export in standard JPEG (.jpg) format unless the portal explicitly requests PNG.
Privacy & Browser Compatibility
All resizing operations execute 100% locally on your device via the HTML5 Canvas API. Your sensitive photographs and personal documents never leave your computer or mobile phone-no images are sent to cloud servers, ensuring total privacy. This tool works flawlessly across all modern browsers including Google Chrome, Mozilla Firefox, Apple Safari, Microsoft Edge, and Android/iOS mobile browsers.
