How to Compress PDF Without Losing Quality

Our tool offers two distinct ways to reduce your file size:

  • Smart Compression (Recommended): This mode only targets embedded images. It recompresses them to a more efficient format while leaving your text and vector graphics untouched. This ensures your document remains searchable and professional.
  • Maximum Compression: This mode converts every page into a high-efficiency image. While this results in the smallest possible file size, the text will no longer be selectable. Use this for documents where size is the only priority.

Optimized for Malaysian Government Portals

Many official Malaysian websites have strict upload limits:

LHDN (Income Tax)

Usually requires PDFs to be under 2MB. Use Smart Mode at 70% quality to easily meet this requirement.

KWSP / EPF

Supporting documents often need to be compressed for quick upload. Tuko ensures your EPF statements stay clear yet small.

Why Tuko is the Safest Way to Shrink PDFs

  • No Uploads: Your files never leave your browser's memory.
  • GDPR & Privacy Compliant: We don't store, see, or track your document content.
  • Faster Processing: Since there's no upload/download time, compression is near-instant.

Compress PDF Online FAQs

Common questions about using our Compress PDF Online tool.

How does Tuko compress PDFs without uploading them?

We use WebAssembly to run a powerful PDF engine directly inside your web browser. This means your files are processed locally on your device's memory, guaranteeing that no sensitive data is ever sent to a server.

Is there a risk of my compressed PDF being read by third parties?

No. Since the compression happens entirely on your own device without any uploads, it is impossible for third parties or even us to access or read your files.

Does compressing reduce the quality of my PDF?

Our 'Smart' mode only compresses the images inside the PDF while preserving the original crispness of text and vector graphics. The 'Maximum' mode performs stronger compression but may slightly lower the overall visual quality.

What is the file size limit for LHDN or KWSP submissions?

Most Malaysian government portals like LHDN and KWSP have a file size limit of 2MB or 5MB. Our 'Smart' compression is usually enough to get your documents under these limits while maintaining readability.
