How do I compress a PDF on a Mac?
Preview can shrink a PDF with its Reduce File Size filter, but it decides the result — you find out how large the file became after it has finished. Working from a limit reverses that: you say the document must be under 10 MB, and the search happens against that number. PX7 PDF Compress measures the saved file again before reporting it as complete.
How do I get a PDF under a specific size, like 10 MB?
Enter the limit and let the app search for the highest quality that fits below it, instead of trying a quality setting and checking the size afterwards. PX7 PDF Compress has presets for 2, 5, 10 and 25 MB and accepts any figure you type, and it says so plainly when a document cannot reach the target safely.
Does compressing a PDF remove the searchable text?
It can, because the usual way to make a PDF much smaller is to turn its pages into images, which discards the text layer. Automatic mode in PX7 PDF Compress protects pages that have selectable text; Flatten All is there for when reaching the size matters more than keeping it, and the comparison shows searchability before you commit.
Can I compress a whole folder of PDFs at once?
Yes. Drop in a folder, or open a Finder selection, and the same limit is applied to every document. Originals are never overwritten — each result gets a new collision-safe filename.
