A PAN card application needs three files at three different sizes: the photograph under 50 KB<\/strong>, the signature under 20 KB<\/strong>, both as JPEG, and supporting documents under 300 KB<\/strong> as PDF. Those limits are identical on Protean<\/a> (formerly NSDL e-Governance) and UTIITSL<\/a>.<\/p>\n

Resize all three free with the PAN card photo resizer<\/a>, the signature resizer<\/a> and the document resizer<\/a>. Everything runs inside your browser, so no file is uploaded to any server.<\/p>\n

Why “File Too Large” Is Often the Wrong Diagnosis<\/h2>\n

The portals validate an upload in a fixed order: format first, then pixel dimensions, then file size. Because the rejection message is generic, a file that fails the first<\/em> check often produces an error people read as a size problem.<\/p>\n

In practice that means you can compress a photograph to 30 KB and still be refused, because the image is landscape rather than portrait, or because it is a PNG that was renamed to .jpg<\/code>. Portals read the file header, not the extension. Compressing harder cannot fix either fault.<\/p>\n

The reliable order of operations is: convert to JPEG, crop to portrait passport proportions, then compress. Doing it in that order removes all three failure modes at once.<\/p>\n

Why the Signature Is the Hardest File<\/h2>\n

The signature limit is 20 KB \u2014 tighter than the 50 KB allowed for a photograph, which surprises people, since a signature looks like the simpler image.<\/p>\n

The reason is how JPEG compression works. It is efficient on smooth gradients such as skin tones and soft shadows, and inefficient on hard, high-contrast edges. A signature is nothing but hard edges: black ink meeting white paper, thousands of times over. A signature scanned at 300 DPI routinely lands between 150 KB and 400 KB despite holding far less visual information than a portrait.<\/p>\n

This also explains why background matters so much. Pure white compresses almost for free, because large uniform areas cost JPEG very little. Cream-tinted paper, a hand shadow, or the faint rules of a notebook page add variation across the entire image \u2014 often enough to hold a borderline signature above 20 KB no matter how hard you compress.<\/p>\n

How to Resize Each File<\/h2>\n
    \n
  1. Photograph.<\/strong> Open the photo resizer<\/a>, upload your image, crop to the passport frame, download. Output is JPEG under 50 KB.<\/li>\n
  2. Signature.<\/strong> Sign in dark ink on blank white A4, photograph it flat in even light, then use the signature resizer<\/a>. Crop tightly \u2014 excess paper is what keeps the file large.<\/li>\n
  3. Documents.<\/strong> Scan at 200\u2013300 DPI in greyscale rather than colour, crop to the page edges, then use the document resizer<\/a> and combine pages into a single PDF.<\/li>\n<\/ol>\n

    Frequently Asked Questions<\/h2>\n

    What is the PAN card photo size in KB?<\/h3>\n

    Under 50 KB in JPEG format, with a white background and passport proportions. The signature must be under 20 KB in JPEG. Both Protean and UTIITSL apply the same limits.<\/p>\n

    Can I use the same files for NSDL and UTI?<\/h3>\n

    Yes. The two agencies operate under identical Income Tax Department specifications, so a correctly sized set of files works on either portal without changes.<\/p>\n

    My file is under the limit but still rejected. What now?<\/h3>\n

    Check format and orientation before compressing further. A PNG renamed to .jpg, or a landscape photograph, fails validation before the size check ever runs \u2014 which is why the error rarely names the real cause.<\/p>\n

    Does compressing to 50 KB reduce the printed quality?<\/h3>\n

    Not visibly. The photograph is printed at roughly 3.5 \u00d7 4.5 cm, and a JPEG at 45 KB carries more than enough data for that area. The difference between a 50 KB and a 500 KB file is not detectable at that print size.<\/p>\n

    Are my files uploaded to your server?<\/h3>\n

    No. All processing happens in your browser using the HTML5 Canvas API. Your files never leave your device and cannot be seen, stored or recovered by us.<\/p>\n
