Prepare CAT 2026 registration images
CAT uses a maximum photo boundary and a physical signature size, so the two tabs intentionally use different dimension units while sharing the 80 KB ceiling.
CAT 1200x1200 photo working canvas
The CAT Photo tab uses 1200x1200 px as the ResizeBox working canvas while respecting the current guidance that the uploaded photograph stay within that pixel boundary.
CAT photo capped at 80 KB
The CAT Photo output has no invented minimum file size; ResizeBox only enforces the current upper limit of 80 KB for the JPG/JPEG portrait.
CAT 8x3.5 cm signature frame
The CAT Signature tab uses the current 8 cm by 3.5 cm horizontal dimensions and supports switching that physical size to pixels.
CAT 150 DPI working density
The CAT presets use 150 DPI as the configured working density so the physical signature dimensions can convert consistently and the image meets the stated minimum density guidance.
CAT recent-photo framing
Use a recent CAT passport photograph on a white background and position the candidate naturally instead of stretching a portrait to fill the square working canvas.
CAT max-only compression handling
Because CAT specifies an upper file-size limit rather than a minimum, the CAT tabs can preserve a smaller clear JPG instead of padding it toward an artificial lower bound.
Prepare CAT registration images
Treat the CAT portrait and signature as different assets: the photo uses a pixel boundary, while the signature uses centimetres and 150 DPI conversion.
Select the CAT document tab
Choose CAT Photo for the 1200x1200 px working canvas or Signature for the 8x3.5 cm horizontal frame.
Fit the CAT source without distortion
Keep the CAT portrait natural inside the working boundary or preserve the complete handwritten signature within the wide physical-size frame.
Keep the CAT JPG under 80 KB
Create the active CAT file and confirm the result is no larger than 80 KB before using it on the 2026 registration portal.
Create CAT 2026 photo and signature files
Prepare the CAT portrait and signature locally with the current working dimensions, 150 DPI handling and max-only 80 KB limit.
CAT 2026 photo and signature FAQ
Review the CAT portrait boundary, signature dimensions, 150 DPI guidance and 80 KB ceiling before uploading registration images.
The current CAT guidance places the photograph within a 1200x1200 px boundary; ResizeBox uses 1200x1200 px as its fixed working canvas rather than claiming every source must originally be square.
The CAT photograph should be JPG/JPEG and no larger than 80 KB, so this preset uses a zero minimum and an 80 KB maximum.
The CAT signature preset uses 8x3.5 cm, matching the current physical-size guidance for the handwritten signature image.
At the configured 150 DPI working density, the CAT 8x3.5 cm signature converts to roughly 472x207 pixels.
The current CAT guidance provides an 80 KB maximum rather than a required minimum, so ResizeBox does not pad CAT files toward an invented lower threshold.
ResizeBox needs a deterministic editing target; the 1200x1200 CAT canvas represents the published upper pixel boundary while the page explains that the official wording is a limit.
Yes. The CAT Signature tab supports cm and pixel units and uses the configured 150 DPI value for the conversion.
Yes. Compare the CAT 2026 output with the active registration guide and upload form because the organizing IIM can revise image instructions in a later cycle.
