Compression

Rewrites the file and keeps text selectable. Many PDFs will not shrink much.

What this tool does

Keep text rewrites the PDF and drops unused objects. Selectable text stays. Many files will not shrink much that way.

Smaller file and Smallest file redraw each page as a picture. That often reduces size for scanned or image-heavy PDFs. The new file is no longer a text document.

When nothing is saved

If the new file is not smaller, the page says so. It does not pretend a reduction happened. Try the smaller-file setting, or leave the original as it is.

Questions

Will every PDF get smaller?

No. Rewriting a file that is already compact often saves nothing. Image-heavy PDFs usually shrink only when pages are redrawn as pictures, which also removes selectable text.

Does compression unlock a password?

No. Password-protected and encrypted PDFs are rejected. SizeUply does not bypass protection.

Are PDF files uploaded?

No. SizeUply reads the PDF in your browser and creates the new file there. The PDF is not uploaded for processing.
