📄 NSDL PAN Document Resizer

📋 NSDL PAN Document Specifications

The NSDL (now Protean) PAN application portal has strict requirements for the three documents you must upload: a passport photo, a signature, and a supporting document (proof of identity/address). Our tool automatically crops and compresses your files to meet these exact specifications:

Note: These specifications apply to both NSDL (Protean) and UTIITSL PAN application portals. Whether you are applying for a new PAN card, a correction, or a reprint, the document requirements are identical.

🔧 How This Tool Works

Our NSDL PAN Document Resizer is a 100% client-side web application. This means all processing — PDF rendering, image cropping, JPEG compression — happens entirely in your browser using JavaScript. Your files are never uploaded to any server.

Step-by-step process:

1. Upload: Click the Upload button on any card. For the supporting document, you can upload a PDF, JPG, or PNG. For photo and signature, only image files are accepted.
2. PDF rendering (documents only): If you upload a PDF, it is rendered to an image using pdf.js at approximately 200 DPI (1654 pixels on the longest edge). This happens locally in your browser — the PDF is never sent to a server.
3. Crop: A visual crop editor (powered by Cropper.js) opens. Drag the crop box to select the region you want. The aspect ratio is locked to the target dimensions (1:1 for photo, 2:1 for signature, A4 portrait for document).
4. Adjust: Use the brightness, contrast, saturation, rotate, and grayscale sliders to fine-tune your image. For signatures, grayscale is enabled by default since signatures are typically black-and-white.
5. Compress: Click "Apply & Compress". The tool creates a canvas at the exact target dimensions, applies your adjustments, and exports as JPEG. It starts at 95% quality and recursively reduces by 5% until the file size is under the KB limit (minimum quality: 15%).
6. Download: The compressed JPEG is displayed in the preview area with its file size shown. Click Download to save it to your device.

Technologies used:

• pdf.js (v3.11.174) — renders PDF pages to canvas images, client-side
• Cropper.js (v1.5.13) — visual crop editor with drag/resize/zoom
• HTML5 Canvas API — image resizing, filter application, JPEG export
• Recursive JPEG compression — quality 95% → 15%, step 5%, until size limit met

🔒 Privacy & Data Security

Your documents never leave your device. This tool runs entirely in your web browser. We do not have a server that receives your files. Here is exactly what happens:

• Your photo, signature, and document files are loaded into your browser's memory (RAM) when you select them.
• pdf.js renders PDFs to canvas images locally — no server round-trip.
• Cropper.js and the Canvas API process the images entirely on your device's CPU.
• The compressed JPEG is offered as a download directly from your browser's memory.
• When you close the browser tab or refresh the page, all data is permanently erased.

We do not use cookies, analytics trackers, or any third-party scripts that could access your files. The only external resources loaded are the open-source JavaScript libraries (pdf.js, Cropper.js) from cdnjs.cloudflare.com and the Plus Jakarta Sans font from Google Fonts.

This tool is safe to use with sensitive documents like Aadhaar, passport, and voter ID. However, always ensure you are on the official pasandtech.com website before uploading any document.

❓ Frequently Asked Questions

📝 Complete Guide to NSDL PAN Document Requirements

What is NSDL PAN?

NSDL (National Securities Depository Limited), now known as Protean eGov Technologies Limited, is one of two authorized agencies in India that process Permanent Account Number (PAN) card applications. The other is UTIITSL (UTI Infrastructure Technology and Services Limited). Both agencies follow the same document upload specifications for online PAN applications.

Why do document specifications matter?

The NSDL/Protean online PAN application portal enforces strict file size and dimension limits to ensure fast uploads and consistent processing. If your photo, signature, or supporting document exceeds these limits, the portal will reject the upload and you cannot complete your application. Common rejection reasons include:

• Photo larger than 30 KB or not 213×213 pixels
• Signature larger than 20 KB or not 400×200 pixels
• Supporting document larger than 300 KB or wrong dimensions
• Wrong file format (portal requires JPEG/JPG)
• Low resolution or blurry image after compression

What documents are accepted as supporting proof?

The NSDL/Protean PAN application accepts the following documents as proof of identity and/or address. You only need to upload one supporting document:

• Aadhaar Card — most commonly used; issued by UIDAI
• Voter ID (EPIC) — issued by Election Commission of India
• Passport — Indian passport (current or expired within 3 years)
• Driving License — issued by RTO
• Bank Certificate — from your bank with your photograph
• ration Card — state-issued ration card
• Pension Payment Order — for pensioners
• Matriculation Certificate — from a recognized board

How to take a good passport photo for PAN

For the best results with our photo cropper, follow these guidelines when taking or selecting your passport photo:

• Use a plain white or light-colored background
• Face the camera directly with a neutral expression
• Ensure good, even lighting (no harsh shadows)
• Keep your face centered and occupying about 60-70% of the frame
• Remove glasses with reflections, hats, and accessories
• Use a high-resolution source image (at least 600×600 pixels)

Our tool will crop and compress the image, but starting with a good-quality source photo ensures the final 213×213 px result is sharp and clear.

How to create a good signature image for PAN

For the signature upload, follow these tips:

• Sign on a clean white sheet of paper with a black or dark blue pen
• Sign at a reasonable size — about 4-5 cm wide and 2 cm tall
• Take a clear, well-lit photo or scan of the signature
• Ensure the signature is centered with white space around it
• Our tool applies grayscale by default, so color doesn't matter
• Crop closely around the signature using the crop tool

Troubleshooting common issues

My compressed photo is too blurry: Start with a higher-resolution source image. The tool compresses to 213×213 px, so a source of at least 600×600 px gives the best results. Avoid over-compressing — if the KB limit allows, the tool will use higher JPEG quality.

My PDF won't load: If your supporting document PDF is password-protected, you will see a prompt to enter the password. Enter the correct password and the PDF will render. If the PDF is corrupted or very large, try saving a smaller version first.

The crop box is wrong size: The crop aspect ratio is locked to the target dimensions. For photo it's 1:1 (square), for signature 2:1 (landscape), for document it's A4 portrait ratio. You can move and resize the crop box within this ratio.
