EPFO UAN Portal PDF Upload Requirements

The Employees' Provident Fund Organization (EPFO) requires all members to complete KYC (Know Your Customer) by uploading supporting documents to the UAN (Universal Account Number) portal. These documents — including Aadhaar cards, PAN cards, bank passbooks, and service certificates — must be uploaded as PDF files under 500KB each.

Failing to meet the file size limit is the single most common technical issue reported during EPFO KYC submissions. Applications are often held up for weeks simply because scanned documents exceed the 500KB threshold. This guide explains how to compress each type of EPFO KYC document to the required size using a completely private, browser-based tool.

EPFO KYC PDF Size Limits by Document

  • Aadhaar Card: PDF under 500KB (the full e-Aadhaar PDF is often 800KB-1.5MB and needs compression)
  • PAN Card: PDF under 500KB
  • Bank Passbook / Cancelled Cheque: PDF under 500KB
  • Service Certificate / Joining Letter: PDF under 500KB each
  • 10th Marksheet / Date of Birth Proof: PDF under 500KB

How to Compress EPFO Documents to Under 500KB

  1. Open the PDF Compressor to 500KB tool on CompressKaro.
  2. Upload your PDF document — drag and drop or select the file from your computer.
  3. Adjust compression quality using the slider. The tool shows the estimated output file size in real time.
  4. Download the compressed PDF — the output file is generated entirely in your browser.
  5. Verify the size by checking the downloaded file properties — it should be under 500KB.
  6. Upload to UAN portal at epfindia.gov.in under the KYC section.

Why Aadhaar PDF Compression Is Tricky

The e-Aadhaar PDF downloaded from the UIDAI website typically contains a high-resolution image of your Aadhaar card along with encrypted signature details, resulting in a file between 800KB and 1.5MB. Compressing this to under 500KB requires a tool that can intelligently reduce image resolution within the PDF while preserving text legibility. The Aadhaar PDF compressor is specifically tuned for this use case, optimizing the embedded image while keeping the text selectable and clear.

What Happens If Your PDF Exceeds 500KB?

The EPFO UAN portal will reject the upload with a generic error message like "File size exceeds the allowed limit." You will then need to compress the document and re-upload it. There is no way to bypass this limit, so preparing documents in advance during the KYC application process is strongly recommended. Using a local compressor means you can iterate quickly without uploading sensitive EPFO documents to third-party servers.

Complete Privacy for EPFO Documents

EPFO documents contain highly sensitive personal information — your Aadhaar number, PAN, bank account details, and employment history. Uploading these to any online PDF compressor exposes them to potential data breaches and server-side storage. CompressKaro's PDF compression runs entirely in your browser using WebAssembly (Ghostscript). Your documents never leave your device, making it the safest choice for EPFO KYC document preparation.
