Match the current CTET photo and signature rules
Use the official CBSE September 2026 physical dimensions and KB limits without manually calculating a suitable image canvas.
Official CTET physical dimensions
Follow the CBSE bulletin sizes of 3.5x4.5 cm for Photo and 3.5x1.5 cm for Signature, rather than relying only on unofficial pixel dimensions from third-party tools.
Correct CTET KB limits
Keep the photograph between 10-100 KB and the signature between 3-30 KB while preserving the active output canvas instead of shrinking dimensions to chase file size.
CTET JPG/JPEG output
Convert supported source images to JPG/JPEG, matching the format required in the CTET September 2026 bulletin for both the latest photograph and scanned signature.
Photo and signature tabs
Switch between Photo and Signature on the same page, and let the crop frame, file-size rule, button label and required output update for the selected CTET document.
Physical-size-aware output
ResizeBox uses the 350x450 photo and 350x150 signature sizes from the current reference preset while leaving DPI unspecified because CBSE publishes no DPI requirement.
Private local processing
Process the CTET photograph and signature locally in your browser, so these application images do not need to be uploaded to ResizeBox servers during resizing.
Prepare CTET images in three steps
Choose Photo or Signature, adjust the crop, then create a JPG within the official CBSE file-size range.
Choose the CTET document
Select Photo or Signature and check the official centimetre dimensions, JPG/JPEG format and KB range shown under Required Output.
Frame the CTET source
Open the matching source, then move or zoom it until the portrait or complete signature fits comfortably inside the active CTET frame.
Create the CTET JPEG
Create the JPEG, fit it into the 10-100 KB photo range or 3-30 KB signature range, and save the prepared result from the download page.
Prepare your CTET photo and signature
Use the current CBSE September 2026 dimensions and file-size limits to create both CTET JPG/JPEG uploads locally without manual calculations.
CTET photo and signature questions
Review the official 2026 dimensions, file sizes, formats and how ResizeBox converts the centimetre requirement into a digital image.
The CTET September 2026 Information Bulletin says the scanned photograph must be 3.5 cm wide by 4.5 cm high, in JPG/JPEG format, with a file size between 10 KB and 100 KB. The bulletin specifies centimetres rather than a mandatory pixel count.
CBSE specifies the scanned signature as 3.5 cm in length by 1.5 cm in height, in JPG/JPEG format, with a file size between 3 KB and 30 KB. The September 2026 bulletin does not state an official signature pixel dimension.
ResizeBox uses the 350x450 px photo size from the current reference preset while preserving the official 3.5x4.5 cm guidance. CBSE does not publish a required DPI for this upload, so ResizeBox leaves DPI unspecified.
ResizeBox uses the 350x150 px signature size from the current reference preset while keeping the official 3.5x1.5 cm guidance visible elsewhere on the page. CBSE does not publish a mandatory DPI for the signature.
The CTET September 2026 bulletin specifies JPG/JPEG format, file-size ranges and dimensions in centimetres, but it does not state a required DPI. ResizeBox therefore leaves DPI unspecified for CTET output instead of forcing one.
The current bulletin requires the scanned photograph to be between 10 KB and 100 KB and the scanned signature to be between 3 KB and 30 KB. This page switches the compression range automatically when you change between Photo and Signature.
Yes. The CTET September 2026 instructions say uploading the scanned Photo and Signature is mandatory and both should be uploaded in JPG/JPEG format. ResizeBox fixes the output format for these presets so the downloaded file matches that requirement.
Yes. This page follows the CTET September 2026 Information Bulletin published by CBSE. Future sessions can change upload instructions, so compare the generated files with the live application form and current bulletin before submission.
