Compress PDF the scans shrink, the text stays text.
Big PDFs are big because of pictures: scans, photos, a Word export full of images. This re-encodes the pictures at the size you choose and leaves the text exactly as it is.
Drag a page to move it. Click one to select it. Arrow keys move a focused page; R rotates it; Delete removes it.
Compress PDF at a glance
content.win compresses where the weight is. Scanned pages and the photos inside text pages are re-encoded at 110, 150 or 200 dpi; the text itself is copied as it is, so a report stays searchable and a scan gets small.

How to compress a PDF
- Drop the PDF in. Every page appears as a thumbnail.
- Pick a size. Smallest for email, Balanced for most things, Sharper if the scan has small print.
- Compress and download. The result line shows the old and new size.
What gets smaller and what does not
- Scans and photo pages
- Rendered again as JPEG at the dpi you chose. A 300 dpi scan at Balanced usually drops by 60 to 80 percent.
- Pages with text
- The text is copied exactly: sharp, selectable, links working. The photos on those pages are re-encoded and scaled to the dpi you chose, which is where a Word export with pictures carries its weight.
- Already small files
- A PDF that is mostly text is often as small as it gets; the result line says so instead of handing you a worse file.
Questions people ask
How do I reduce a PDF's file size?
Drop it in, pick Balanced, click Compress and download. The result line shows the before and after.
Will the text still be selectable?
Yes. Text is never turned into pixels; only the pictures are re-encoded.
Why did my PDF barely shrink?
It was mostly text, or its pictures were already small or in a format this tool leaves alone (PNG-like graphics, images with transparency). Try Smallest; if nothing gets smaller, the result line says so and no file is saved.
What dpi should I pick?
Balanced (150 dpi) reads well on screens and prints fine. Smallest (110 dpi) for email limits. Sharper (200 dpi) for small print or forms you need to zoom into.
Is there a size limit?
No fixed one; very large files depend on your device's memory.
Can I compress several PDFs at once?
Yes, but they come out as one combined PDF. For separate files, do them one at a time.
