How to Resize Driving Licence Photo Online: Tool Workflow

Upload Photograph
Click 'Upload Image' or drag and drop your selfie, camera photo, or scanned picture into the tool canvas.
Crop & Choose Dimensions
Select the Driving Licence (35×45 mm) preset. Adjust the crop frame so your face and shoulders are nicely centered.
Set KB Target (10–20 KB)
Choose the target compression range. The tool automatically applies JPEG discrete cosine transform to stay strictly within 12–18 KB.
Preview & Download
Inspect the live preview and file weight badge, then click 'Download Ready Photo' to save your compliant JPG file.
Sarathi Parivahan Driving Licence Photo Requirements
The Sarathi Parivahan web application (sarathi.parivahan.gov.in) is managed under MoRTH and handles licence issuance across all Indian states and Union Territories. When applicants reach the 'Upload Documents / Upload Photo and Signature' stage, the portal runs automated client-side and server-side validation scripts.
Facial Posture & Expression
Direct frontal look with both eyes open and mouth closed. Neutral facial expression without smiling or tilting the head.
Eyewear & Headwear
Clear prescription glasses are allowed if there is no glare. Dark sunglasses, tinted lenses, caps, and masks are strictly forbidden.
Lighting & Background
Even illumination without hard shadows across the face or backdrop. Background must be plain white, off-white, or light grey.
Driving Licence Photo Size in KB: The 10 KB to 20 KB Rule
A frequent hurdle applicants encounter is the tight file size window on Sarathi Parivahan. Unlike many job portals that allow up to 50 KB or 100 KB, the Sarathi system strictly bounds uploads:
If your photo file is 20.5 KB, the portal triggers: "Upload image file size should be between 10KB to 20KB". If you over-compress down to 8.5 KB, it rejects the file as undersized.
Our compression algorithm uses iterative binary search quantization to calibrate the output file weight to approximately 14 KB to 18 KB—safely inside the portal's acceptable range.
If you have a high-resolution 3 MB camera image, use our Compress Image to 20KB or MB to KB Compressor to safely downscale it.
Driving Licence Photo Size in Pixels
Pixel dimensions depend on the digital display Density (DPI / PPI). When sizing your DL photograph, use these standard pixel metrics:
| DPI Level | Pixel Dimensions (W × H) | Best Use Case |
|---|---|---|
| 300 DPI (High Print Standard) | 413 × 531 pixels | Smart card printing & official archival |
| 200 DPI (Balanced Web) | 276 × 354 pixels | Fast loading within 10–20 KB limits |
| 100 DPI / Screen (Standard) | 138 × 177 pixels | Low-bandwidth portal submissions |
| Sarathi Web Default | 420 × 525 pixels | Optimal aspect ratio (4:5 or 7:9 scaling) |
Driving Licence Photo Size in CM and MM
For physical verification, RTO offline forms, and physical photograph submissions, the measurements are defined as:
35 mm × 45 mm
Width 35 mm, Height 45 mm
3.5 cm × 4.5 cm
Width 3.5 cm, Height 4.5 cm
1.38 in × 1.77 in
Standard 7:9 passport proportions
You can review the full comparison in our Passport Size Photo in CM Guide and Passport Photo Dimensions Guide.

How to Resize Driving Licence Photo on Mobile (Android & iPhone)
You do not need to install complex photo editing software or third-party mobile apps that compromise your personal privacy. Our browser-based tool works natively on mobile devices:

- Tap 'Upload Image' and select your photo from the Gallery.
- Adjust the 35×45 mm framing crop around your face.
- Confirm the target is set between 10 KB and 20 KB.
- Tap 'Download Ready Photo' to save the optimized JPG file to your
Downloadsfolder.
On iPhone & iPad (Safari)
- Open Safari and access this Driving Licence Photo Resizer page.
- Tap 'Upload Image' and pick your photo from the Photo Library.
- Safari converts the HEIC image to RGB canvas data automatically.
- Align your face within the crop markers and ensure 10–20 KB is selected.
- Tap 'Download Ready Photo' to save the JPG directly into the Files app or Photos.
How to Compress DL Photo Without Losing the Best Possible Quality
Compressing an image from 3 MB to under 20 KB is a lossy process. Claiming "zero loss" at 20 KB is technically impossible, but you can retain maximum visual crispness and facial recognition clarity by following these key rules:
1. Crop Empty Margins First
Never compress a full-length body picture down to 20 KB. Crop tightly around the head, neck, and shoulders so every byte is dedicated to your face.
2. Strip EXIF Metadata
Camera EXIF tags contain 20–80 KB of unnecessary GPS and lens data. Our browser tool strips this payload entirely, leaving maximum budget for image pixels.
3. Avoid Heavy Shadows
Shadows and busy backgrounds create high-frequency noise that bloats file size. A clean, uniform background compresses far sharper at 15 KB.
How to Fix "Invalid Photo Dimensions" or "File Size Must Be 10-20 KB" Error
When submitting images on the Sarathi Parivahan portal, applicants commonly encounter upload validation errors. Here is how to fix them immediately:
Error: "File size must be between 10 KB and 20 KB"
Fix: Your file is either 9.8 KB or 20.2 KB. In our tool, ensure the target is set to 15 KB. This guarantees the saved file is safely within the allowed 10–20 KB threshold.
Error: "Invalid Image Dimensions / Aspect Ratio"
Fix: This occurs when an image is square (1:1) or panoramic instead of standard 35×45 mm (7:9 ratio). Select the Driving Licence preset in our tool and re-export.
Common Driving Licence Photo Rejection Reasons
RTO officers reject uploaded documents during online application scrutiny if they violate standard identity criteria. Verify your photo against this checklist before uploading:
Photos taken outdoors, in cars, or against patterned curtains are strictly rejected. Use a plain white or light wall.
Eyes must be clearly visible without tinted glass or lens flash reflections hiding the pupils.
Side profiles or tilted portraits fail verification. Maintain a straight, square-on posture facing the lens.
Extreme compression or low-light capture causes pixelation. Facial features must remain sharp and recognizable.
The Sarathi server blocks files larger than 20 KB or smaller than 10 KB with an immediate upload error.
Attempting to upload a PDF or PNG for the photo or signature slot will fail. The portal requires standard JPG.
JPG/JPEG Format for Driving Licence Photo
Why do transport portals like Sarathi Parivahan mandate JPG / JPEG instead of PNG or PDF?
High Compression Efficiency
JPEG uses discrete cosine transform lossy compression, which is ideal for photographic portraits. It easily reaches 15 KB while retaining smooth skin tones.
Universal Database Support
RTO databases across Indian states are programmed to parse and store standard 24-bit RGB JPEG binaries directly into smart card chip profiles.
Automatic PNG/WEBP Conversion
When you upload a PNG, WEBP, or HEIC photo into our tool, it automatically converts the file to compliant JPG format before download.
How to Change or Update Photo in Driving Licence Online
If your photograph on an existing Driving Licence is old, faded, or unclear, you can update it through the Sarathi Parivahan portal:
- Visit the Official Sarathi Portal: Go to sarathi.parivahan.gov.in and select your State.
- Select "Apply for DL Services": Choose "Services on DL (Renewal / Duplicate / Change of Address / Others)".
- Enter Licence Details: Enter your Driving Licence Number and Date of Birth to fetch your profile.
- Select Update Service: Choose "Change of Biometrics / Photo & Signature Update" or select DL Renewal with biometric update.
- Upload New Photo & Signature: In the 'Upload Documents' step, upload your freshly formatted 10–20 KB photo and signature prepared on this tool.
- Pay Fee & Book Slot (if required): Complete the fee payment online. Depending on your state's faceless service rules, the update will be verified digitally or via a brief biometric visit at your zonal RTO.
