Frequently asked questions

Will my PDF still be clear at 150KB?

Yes. Our algorithm keeps text sharp and lightly optimizes images, so your document stays readable while it drops under the 150KB limit.

Can I compress scanned PDF files to 150KB?

Absolutely. This tool is tuned for scanned documents under 150KB, though very large scans may need a little resizing before they reach the target.

What if I need more or less compression?

Use the Compress PDF to 100KB tool for smaller files, or the Compress PDF to 200KB tool when you want to keep more image detail.

Is my document safe and private?

Your file is handled securely during compression and is not kept for the long term, so your certificates, resumes, and forms stay private throughout the process.

What file types can I upload?

This tool works with PDF files only. Drag and drop a PDF into the upload zone, or click it to browse and pick a file from your device.

What if my file is already under 150KB?

If your PDF is already 150KB or smaller, the tool lets you know that no compression is needed, so you avoid shrinking a file that is already small enough.

Need a different target? Try the Compress PDF to 100KB tool for a smaller file, or the Compress PDF to 200KB tool to keep more image detail.
