If the left thumb is unavailable
IBPS provides alternative finger or toe instructions for candidates who cannot provide a left thumb. Follow that notice and identify the uploaded finger or toe where required.

Frequently Asked Questions
What is the IBPS thumb impression size?
The current IBPS PO scanning guide specifies JPG/JPEG, 240 x 240 pixels in 200 DPI (3 cm x 3 cm preferred), and 20KB to 50KB. Verify the active recruitment notice before submitting.
What is the thumb impression size for IBPS, SBI, and RRB?
Do not assume one rule for every bank or RRB cycle. Use the IBPS preset only when the active notice matches 240 x 240 pixels and 20KB to 50KB, and follow a different notice when it states different limits.
Is it safe to upload my biometric thumbprint here?
Yes, 100%. Our tool runs completely client-side in your web browser. Your thumb impression is processed locally using the canvas API and is never uploaded or saved to our servers. You can even disconnect your internet while using the tool.
Why does my exam portal reject my thumb impression?
Common causes are the wrong file size, non-JPG format, unclear or smudged ink, dark background, excess whitespace, or uploading the thumb in the wrong field. Correct the property named by the active portal instead of relying on a generic preset.
