Open the Resizer ToolCTET's photo is captured live via webcam on the official portal — no upload is accepted there. This fallback lets you prepare a standard 3.5×4.5cm photo for other purposes.
Your source image is smaller than the required output size — the result may look slightly soft. A higher-resolution original is recommended.

CTET Photo & Signature Size Guide
Every year thousands of CTET applications are held back because the photo or signature does not match the size printed in the notification. Central Board of Secondary Education (CBSE) checks three things on every upload: the pixel dimensions, the file size in KB, and the file format. This freeCTET photo & signature resizer (3KB–100KB) is pre-set to those exact figures, so you can upload any phone photo or scan and download files the portal will accept on the first try.
The CTET photo must be 350×450px and 10KB–100KB, while the signature must be 350×150px and 3KB–30KB. Both are uploaded as JPEG files.
How to Resize Your Photo and Signature for CTET
- Take a fresh photo against a plain white or light wall in daylight, or scan your signature signed on clean white paper.
- Upload the image in the CTET resizer above — JPG, PNG and HEIC from iPhone all work.
- Drag and zoom the crop box to frame your face or signature. The box is locked to the official CTET aspect ratio, so the output never looks stretched.
- For signatures, switch on the scan enhancer to remove paper shadows and get a pure white background.
- Download. The tool compresses the file to land inside the allowed KB range while keeping the exact pixel size, then shows you the final size before you save it.
CTET Photo Requirements
Use a recent colour photo with your face centred and clearly visible, a plain light background, and no filters or heavy edits.
CTET Signature Requirements & White Background
Sign in your normal running handwriting — not capital letters — with a black or blue pen on plain white paper, unless the notification says otherwise. Phone scans usually come out grey or shadowed, which looks unclear once shrunk to 350×150px. Our built-insignature background remover evens out the lighting and clamps the paper to a pure white background while keeping the ink dark.
Add Name and Date on Photo for CTET
CTET does not normally ask for a name and date strip, but some recruitment cycles and document-verification rounds do. If yours does, turn on the stamp toggle in the resizer above or use the dedicated add name and date on photo tool — the white strip is added at the bottom and the final file still meets the CTET size.
Resizing CTET Photo and Signature on Mobile
You do not need a computer or a cyber café. Open this page in Chrome or Safari on your phone, tap upload, and pick the photo straight from your gallery or camera. Pinch to zoom inside the crop box, then download — the file saves to your Downloads or Files app, ready to attach in the CTET application form. Since all processing happens on your phone, it works even on a slow connection once the page has loaded.
Common Reasons CTET Uploads Get Rejected
- File size outside the allowed range — too large, or compressed below the minimum KB.
- Wrong pixel dimensions or a stretched image from a basic resize app.
- Dark, grey or shadowed background on the photo or signature.
- Signature in capital letters, or photo and signature uploaded in each other's slots.
- PNG or PDF uploaded where a JPG/JPEG is required.
The specification on this page was last checked against public sources. Always read the latest CTET notification before final submission, and if the official figures change, set a custom size in the generic photo and signature tools.
CTET Photo & Signature FAQs
What is the CTET photo and signature size?
Photo: 350×450px, 10–100KB. Signature: 350×150px, 3–30KB, both in JPEG format.
How do I reduce my CTET photo and signature to the required KB size?
Upload your image to the CTET resizer on this page. It crops to the exact CTET dimensions and compresses the file into the 3KB–100KB window, keeping the highest quality that fits.
Do I need to add name and date (DOP) on the CTET photo?
The CTET specification we follow does not ask for a name and date printed on the photo, so the stamp is off by default. If your current notification does require it, tick “Add name & date to photo” in the tool above and enter the actual date the photo was taken.
How do I make my CTET signature background pure white from a mobile camera photo?
Sign on plain white paper, photograph it in good light without shadows and upload it here in Signature mode. Keep “Clean Paper Background (Signature Enhancer)” on — it removes shadows and grey paper tone so the background is pure white, then sizes the file to 350×150px, 3KB–30KB.
Why is my CTET signature getting rejected or looking blurry?
Usually because the signature was cropped with too much empty space, the background is grey or shadowed, or the file was over-compressed. Crop tightly around the ink, sign with a darker pen and keep the Signature Enhancer on — the CTET preset then keeps the signature sharp within 3KB–30KB.
How do I reduce my CTET photo and signature size on mobile without losing quality?
Open this page in your phone’s browser, upload from your gallery or camera and tap Process & Download. The tool picks the highest JPEG quality that still fits 3KB–100KB, and only reduces resolution if it must — no app needed.
Can I upload an iPhone HEIC or PNG image for the CTET form?
Yes. Upload the HEIC or PNG file directly — it is converted to JPG in your browser and compressed to the CTET requirement in one step. If your browser cannot read a particular HEIC file, export it as JPEG from the Photos app and try again.
Is it safe to upload my CTET photo and signature on SarkariPhoto.in?
Yes. It is completely free with no watermark or sign-up, and every step runs inside your browser — your photo and signature are never uploaded to any server.
