Is my document secure?

Yes. The PDF compressor runs entirely client-side, meaning your document is processed in your browser memory and never uploaded to our servers.

Does it support password-protected PDFs?

Yes. The tool will prompt you for the password to decrypt the file locally before compressing it.

Uploading documents to the UPSC portal or updating your details on the UIDAI Aadhaar website requires PDF files to be under 300KB. This tool helps you compress your PDFs to meet these limits securely.

How to Compress PDF to 300KB

1. Click the **Go to PDF Compressor** button. 2. Upload your PDF file. 3. The tool adjusts resolution and removes unneeded metadata locally. 4. Download your optimized PDF under 300KB instantly.

Why 300KB is Important

Both UPSC and UIDAI enforce a strict 300KB limit for certificate and identity uploads. Files exceeding this limit will fail to upload, but our local compressor helps you avoid registration issues.
