Resize Your Signature to 70KB for RRB ALP / Technician
Fit your scanned signature into the 30-70KB range at 50mm x 20mm for the RRB ALP application.
What Is This Tool?
RRB ALP and Technician applications need the signature scanned at 50mm by 20mm and sized between 30KB and 70KB — a specific enough combination that a straight phone-camera scan rarely fits without editing. Upload your signature scan and it's resized to the 50x20mm dimensions and compressed into the 30-70KB range RRB specifies, ready to attach to the application form. ### Official Commission Guidelines & Specifications RRB ALP application guidelines require signatures to be uploaded as JPG/JPEG files between 30 KB and 70 KB, with standard dimensions of 50 mm x 20 mm (140 x 60 pixels). The signature must be executed in running handwriting using a black or dark blue pen on clean white paper. Signatures in capital block letters or faint pencil are strictly disallowed by Railway Recruitment Boards. Crisp stroke definition avoids rejection during recruitment processing. ### Why Use DoctorDocs In-Browser Resizer? Our RRB ALP Signature Resizer enhances pen stroke contrast, crops excess whitespace, and targets the exact 30KB-70KB file size window required by RRB online portals. Free, private, and instantaneous. ### 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.
