Frequently Asked Questions

Why is the text not selectable in the compressed PDF?

To achieve maximum compression, we convert each page to an optimized JPEG image. This process, called rasterization, significantly reduces file size but means text becomes part of the image and cannot be selected or searched.

How much can I reduce my PDF size?

Results vary depending on the original PDF content. Image-heavy PDFs can often be reduced by 70-90%. Documents with mostly text may see smaller reductions but still significant savings.

Is this safe for sensitive documents?

Absolutely. All processing happens entirely in your browser. Your PDF is never uploaded to any server, making this the safest option for compressing confidential contracts, financial documents, and private information.
