Resize Your Signature to 30KB for JEE Main
Fit your scanned signature into the 4-30KB range at 3.5cm x 1.5cm for JEE Main.
What Is This Tool?
JEE Main asks for the signature scan at a specific 3.5cm by 1.5cm size, compressed to between 4KB and 30KB — a narrow band that most default phone or scanner exports miss by a wide margin. Upload your signature scan and this tool crops it to the 3.5x1.5cm dimensions and compresses it into the 4-30KB range, ready to upload to the JEE Main application without a rejected-file loop. ### Official Commission Guidelines & Specifications NTA JEE Main specifies candidate signatures must fall between 4 KB and 30 KB in JPG/JPEG format, with dimensions of 3.5 cm x 1.5 cm (around 140 x 60 pixels). Candidates must sign in running hand using a black ballpoint pen on clean white paper. Signatures in capital letters, low-contrast scans, or images with blurred edges will fail online validation. Clean margins and sharp strokes ensure hassle-free acceptance. ### Why Use DoctorDocs In-Browser Resizer? Our JEE Main Signature Resizer isolates signature strokes, eliminates paper shadows, and compresses the JPG to under 30 KB. Complete your engineering entrance registration in seconds. ### 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.
