How to Compress PDF to 500KB (or Less) - Free Online Tool

Why You Need to Compress PDF to 500KB

Most job portals, government websites, and university applications have strict file size upload limits—often 500KB or 200KB. Even email providers limit attachments to 25MB.

If your PDF is too big, you need a PDF compressor. But be careful: many online tools upload your sensitive documents to their servers.

ExactPDF is different. We compress your PDF locally in your browser. Your file never leaves your device.

Steps to Compress PDF to 500KB

Open the Tool: Go to ExactPDF Compress PDF.

Select Your File: Drag and drop your PDF.

Choose Compression Level:

* Medium: Good balance for documents (usually gets below 500KB). * High: Strong compression (great for < 200KB). * Extreme: Maximum reduction (best for < 100KB).

Click Compress: Processing happens instantly.

Download: Save your smaller PDF.

How to Check Your File Size

After compression, check the file size in your file explorer: * Windows: Right-click > Properties * Mac: Right-click > Get Info

If it's still over 500KB, try the "Extreme" compression level or split the PDF into smaller parts.
