"Invalid dimensions" means the portal checked your photo's exact pixel width and height — not just the file size — and your file didn't match. A correctly-sized-in-KB photo can still fail this specific check.

Why this is different from a file-size error

File size (KB) and pixel dimensions (width × height in pixels) are two separate checks, and portals often validate both independently. A photo can be well within the KB range and still get "invalid dimensions" because its width or height in pixels doesn't match what's required — for example, a 300×300 px photo uploaded where 200×230 px is required.

The three ways this happens

  1. Wrong aspect ratio. A square photo uploaded where a rectangular one is required (or the reverse) — cropping fixes this, resizing alone doesn't.
  2. Right ratio, wrong absolute size. A correctly shaped photo that's simply the wrong pixel count — some portals check for an exact match, not just a ratio.
  3. A resize that stretched instead of cropped. Forcing an image to fit a target pixel size without cropping first distorts the proportions, which some portals detect and reject even if the raw pixel count looks right.

Fix it

  1. Identify the exact required pixel dimensions and ratio from the notification.
  2. Upload above and choose the matching exam or document preset — the tool crops to the correct ratio first, then resizes to the exact pixel dimensions, rather than stretching.
  3. Download and re-upload the corrected file.
