How our compression levels work
What changes when I choose Extreme or Recommended?
Both modes rebuild each PDF page as a compressed image. Extreme produces lower-resolution pages; Recommended uses higher-resolution pages and JPEG quality. This can be useful for scans and photo-heavy PDFs, but the output no longer contains selectable text, interactive forms, existing PDF links or valid original digital signatures.
Which mode keeps searchable text?
Choose Less compression. It reorganizes PDF data without converting pages to images. Files that are already optimized might not get any smaller, so we return the original file when it is the smallest result.
Why is my PDF not smaller?
A compact or mostly text-based PDF may already be efficient. Rasterizing text can even increase file size. PDFLife checks the resulting file size and does not claim savings when none occurred. Image-based modes process up to 40 pages in your browser.
