Resize PDF to 300KB - Free Instant Tool

UPSC, state PSC, NDA, and CDS applications often require one exact file size limit, not a vague small or medium compression setting. This tool is built around KB targets so you can prepare documents for portals that reject files even a few KB over the limit.

The compressor first removes metadata and saves the PDF with object streams. For scanned PDFs, it can render pages to compressed JPEG images and rebuild the PDF to reach smaller targets.

The tool is designed for India-first workflows: UPSC forms, SSC applications, railway uploads, banking KYC, college admissions, and job portals. These forms are usually completed on a deadline, often from mobile, and they need a fast answer.

No server upload is the core privacy promise. Your PDF stays inside your browser while the compression logic runs locally. That also keeps the tool fast and free because there is no upload queue.

300KB is useful when a portal asks for a strict upload size and rejects larger PDFs. Text-based documents usually compress easily, while scanned PDFs may need stronger image compression.

If your PDF is already below the target, the tool still strips metadata and prepares a clean download. If the target is very aggressive, check readability before uploading to the portal.
