How this compressor works

Each page is rendered and saved as an optimised image, then rebuilt into a new PDF. This is very effective for scanned and photo-heavy PDFs, which are the files that usually exceed upload limits.

Because pages become images, text in the compressed file can no longer be selected or searched. For text-only PDFs that are already small, the result may be larger, and we will tell you if that happens so you can keep the original.

Getting under 200 KB

Choose Under 200 KB and turn on grayscale if the document is black and white. If the PDF has many pages and still does not fit, use Split PDF to send only the pages required, or check whether the portal allows a larger limit.

Frequently asked questions

How do I compress a PDF to 200KB?

Choose the PDF, tap Under 200 KB and then Compress PDF. Turn on grayscale for extra savings.

Why can I not select text after compressing?

This method stores each page as an image to save space. Keep the original if you need selectable text.

Why did my PDF get bigger?

Text-based PDFs are already efficient. Image conversion cannot improve them. Keep your original file in that case.

Are my files uploaded to your server?

No. This tool runs entirely inside your web browser using JavaScript. Your files are processed on your own phone or computer and are never sent to us or anyone else. You can even disconnect from the internet after the page loads and it will still work.

Is there a page limit?

No fixed limit, but long PDFs take longer because every page is processed on your device.
