Compress PDF to 150 KB

How do I compress a PDF to 150 KB?

Upload your PDF to our free compressor, select a compression level, and download the result. If the first attempt is still over 150 KB, try a higher compression setting or split the PDF into smaller sections.

Why do I need to compress a PDF to 150 KB?

Many platforms that require passport photo and ID document scans have a strict 150 KB file size limit. These limits exist to save storage and bandwidth on their servers.

Will compressing the PDF reduce quality?

For text-heavy PDFs, compression has almost no visible impact. For PDFs with many high-resolution images, higher compression levels may slightly reduce image sharpness — but text remains crisp.

Is it safe to compress PDFs online?

With our tool, yes — 100% safe. All compression happens inside your browser using JavaScript. Your PDF is never uploaded to any server and remains completely private on your device.

What if my PDF is still over 150 KB after compression?

Try splitting the PDF into multiple pages. If it contains scanned pages, try OCR tools to convert scans into text PDFs which compress much better. High-resolution images embedded in the PDF are usually the biggest factor.
