Resize Your Thumb Impression to 50KB for IBPS PO / Clerk
Get your left thumb impression scan to the 20-50KB range at 240x240 pixels for the IBPS application.
What Is This Tool?
Alongside the photo and signature, IBPS PO and Clerk applications ask for a scan of your left thumb impression — a square 240x240px image between 20KB and 50KB. It's an easy one to get wrong on the first try since most scanning apps default to much larger files. This tool crops your thumb impression scan to the required square dimensions and compresses it into the 20-50KB range IBPS expects, so it uploads cleanly without a rejection and a re-scan. ### Official Commission Guidelines & Specifications IBPS requires candidates to upload a left thumb impression (LTI) between 20 KB and 50 KB in JPG/JPEG format, with standard dimensions of 240 x 240 pixels (3 cm x 3 cm at 200 DPI). The impression must be taken on clean white paper using blue or black ink stamp pads. Ridges of the thumb impression must be distinct, sharp, and free from smudging. If a candidate does not have a left thumb, right thumb impression or finger impressions may be used as per official IBPS notification rules. ### Why Use DoctorDocs In-Browser Resizer? The DoctorDocs IBPS Thumb Impression Resizer isolates the biometric impression, sharpens fine ridge patterns, and guarantees the exact 240 x 240 pixel framing under 50 KB. The entire conversion happens securely inside your browser without uploading biometric data. ### Step-by-Step Upload Checklist & Common Errors to Avoid Before submitting your application on the official recruitment or admissions portal, review this essential pre-upload checklist: 1. Ensure the final file format is strictly JPG or JPEG as specified by the conducting board. 2. Verify that the image dimensions in pixels or centimeters match the official notification to avoid portal distortion. 3. Check that the file size is strictly within the mandated minimum and maximum kilobytes limit. 4. Confirm that the image preview appears sharp, upright, and without dark compression artifacts or blurred borders. 5. If using a mobile phone photo, make sure ambient daylight is even and free from finger shadows or background objects. Using DoctorDocs ensures your image passes automated server-side verification filters on the first attempt without rejection.
