Work with PDFs
PDF Tools has three tabs: Compress, Merge and Split. They need no extra software on any platform.
Password-protected PDFs cannot be opened. The app reports Could not open … — is it a valid, unencrypted PDF? Remove the password in another program first.
Compress
Open PDF Tools. The Compress tab is open.
Add one or more PDFs.
Select Compress PDF (or Compress 3 PDFs).
The PDF is rebuilt with the strongest compression for its internal data. Results get _compressed added to the name, and each row shows the size before and after.
PDFs made mostly of large scanned images may shrink only a little, because the images themselves are not changed.
Merge
Open the Merge tab.
Add at least two PDFs, in the order you want them.
PDFs are combined in the order they were added. To move a file, remove it and add it again; it goes to the end.
Select Merge, which shows the count, for example Merge 3 PDFs.
The result is named after the first PDF with _merged added. Its row shows the total number of pages.
Split
Open the Split tab and add one or more PDFs.
Under Split mode, choose:
- Every page (default): each page becomes its own PDF.
- Page range: one new PDF with only the pages from From page to To page, both included.
Select Split into pages or Extract pages.
Every page creates a folder named after the PDF with _pages added, holding files such as report_page_01.pdf, report_page_02.pdf. Page range creates one file such as report_p2-5.pdf.
If the range is not valid (empty, below 1, or To page before From page), the app asks you to Enter a valid page range, e.g. 2 to 5. A range past the last page fails with a message giving the allowed range.
