Compression level
This rasterizes each page into an image to shrink file size. Text will no longer be selectable or searchable in the result — ideal for scanned documents, not for text-heavy reports you need to edit or search later.
Files are processed locally — nothing is uploaded to any server
How PDF compression works here
Your PDF's pages are rendered as images, re-compressed at your chosen quality, and rebuilt into a new PDF. This is very effective for scanned documents, photos, or image-heavy files, which is where PDF size usually comes from in the first place.
When not to use this
If your PDF is mostly typed text you need to search, copy, or edit later, this tool isn't the right fit — rasterizing turns the text into a picture of text. For that kind of file, reducing embedded image quality with dedicated desktop software preserves the text layer better.
Which compression level should I choose?
"Balanced" is a good default for most scanned documents. Choose "Smallest file" for strict upload limits where visual quality matters less, or "Best quality" when the file still needs to look sharp when printed.
