PX7 PDF Compress preview showing a sample photo document reduced from 1.1 MB to 126 KB using Flatten every page
This sample previews a reduction from 1.1 MB to 126 KB with Flatten every page. That method turns pages into images: text, links and form fields are no longer interactive. Results depend on the document and settings. Demo photo: Clay Banks / Unsplash.

Set a size limit and verify the exported PDF.

Actually under the target

Enter 2 MB, 10 MB or another hard limit. The saved PDF is measured again before it is reported as complete.

The highest quality that fits

Compress searches automatically instead of asking you to guess at an arbitrary low, medium or high setting.

Keep searchable text

Automatic mode protects pages with selectable text. Use Flatten All only when reaching the target matters more than retaining that text layer.

See the real result first

Compare Original and Compressed, including verified size, savings, page count and searchability, before processing the batch.

One PDF or a whole folder

Open a Finder selection, drop complete folders or use the Shortcuts action. Apply one exact rule to every document.

Image resolution, grayscale and metadata settings

Choose maximum image resolution, optional grayscale and metadata removal. The app explains when a protected document cannot reach the requested size safely.

Your originals stay untouched

Every result uses a new collision-safe filename. Existing files are never overwritten.

Questions about PX7 PDF Compress

Which Macs can run PX7 PDF Compress?

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 custom limits of at least 50 KB, 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.
