NSDL Protean PAN Image Compression and Resizer Tool

Are you submitting a PAN Card application online through the official Protean NSDL portal? One of the most common issues applicants face is uploading their passport photograph and scan of their signature. The NSDL system has a automated, strict validation protocol. Unless your photo is exactly 212x212 pixels and signature is exactly 400x200 pixels, and both files are smaller than 50KB, your upload will fail.

OptiKit's NSDL Image Compressor solves this problem. It allows applicants to crop, resize, and compress their passport photos and signature scans completely in the browser without uploading any files to server-side queues. It also ensures the necessary 600 DPI density tags are added, keeping the upload fully compatible with Protean regulations.

NSDL Image Compressor FAQs

For NSDL (Protean) PAN card applications, the passport photo must be exactly 212 x 212 pixels (aspect ratio 1:1) and the file size must be under 50KB. The signature scan must be exactly 400 x 200 pixels (aspect ratio 2:1) and the file size must be under 50KB. Both files must be in JPEG format at 600 DPI resolution.

Yes. Protean/NSDL portals reject files with low DPI settings (72 or 96 DPI). Our browser-side processor automatically rewrites the JPEG binary density markers, forcing a strict 600 DPI resolution header in the output file, assuring 100% submission success without complex setups.

Upload failures are almost always due to incorrect specifications: (1) Dimensions are not exactly 212x212 px or 400x200 px, (2) The file size is larger than 50KB, (3) The file is PNG, WebP, or PDF (only JPG/JPEG is allowed), or (4) The DPI metadata is under 600.

Absolutely. OptiKit performs all resizing, cropping, and compression entirely offline in your browser. Your photo or signature scan is never sent to our servers, assuring maximum security and 100% data privacy.

Signatures must be written with a thick black ink pen on clean, blank white paper without any lines or designs. Use a stable smartphone shot or a scanner to capture the signature before uploading it to our compressor.
