Compress PDF to 400KB

What is a PDF Compression Tool?

A PDF compression tool reduces the size of PDF documents while preserving the elements that matter most.

Large PDF files often become difficult to upload online, email, store, or share quickly. Compressing PDFs makes documents lighter, faster, and easier to manage across devices.

PDF compression is widely used by students, office workers, businesses, teachers, freelancers, and government job applicants.

Why People Need to Compress PDF Files

Many websites and online portals have strict file size limits, so users often run into messages like "File size too large", "Upload failed", "PDF exceeds limit", or "Document size not supported".

Instead of recreating documents manually, users compress PDF files to reduce size quickly and keep uploads moving.

Compress PDF for Government Job Applications

Government recruitment portals often require PDF documents under specific limits.

Candidates regularly need to compress files such as resumes, scanned signatures, Aadhaar cards, certificates, mark sheets, and other ID proof documents.

This is one of the most common reasons people use PDF compression tools online.
