What do the Good, Small and Tiny levels do?

In strong mode pages become JPEG images: Good is up to 1800 px wide at 80% quality, Small 1300 px at 65%, Tiny 900 px at 50%.

What if light mode barely makes it smaller?

If it saves less than 5%, you get no download; you see the size and can try strong mode instead.

Is there a page limit for strong compression?

Yes, 200 pages. Split a longer PDF first.

Compress a PDF

Make a PDF smaller: a light pass that keeps the text selectable, or a strong pass that re-renders pages as images at the quality you pick.

When you'd use it

A job application portal rejects your CV and certificates because the upload is over its limit.
A scanned stack of receipts is too large to email to your accountant.
A photo-heavy brochure needs to open quickly on phones.

Just say what you need

There are no menus to learn. Drop your file on pdfagents.ai and type it the way you would say it:

“make this small enough to email”
“compress it”
“shrink it under 5 MB”

How it works

Drop the PDF.
Choose light or strong, and the quality.
See the before/after size and download.

The strong mode turns pages into images, so text is no longer selectable. If nothing can be gained, you are told instead of handed a bigger file.
