What gets smaller
Most of a large PDF is usually its pictures: scanned pages, photos, screenshots. Pictures bigger than the page needs are scaled down and saved again at the quality you pick. Text, fonts and vector drawings stay sharp, since they are left exactly as they were.
Which level to pick
Recommended keeps pictures at 150 dots per inch, fine for reading on screen and for everyday printing. Light keeps 220 for sharper prints. Strong goes down to 100, for email attachments and upload portals with tight limits.
When a PDF won’t shrink
A PDF that is mostly text, or one that was already compressed well, has little left to take out. If the pictures can’t be made smaller, you still get a copy without the document details, unless even that would be bigger; then you get your original back untouched and the list tells you so.
Hidden details come off
Every PDF that comes back smaller also leaves without its document details: author, title, the app that made it, creation dates and embedded XMP data.
Your files stay with you
Your PDFs are opened and saved on your own device. Nothing is uploaded, nothing is stored, and you don’t need an account. Close the tab and they’re gone.
From our tests
- How much a PDF really shrinks, and when the level matters
Photos and scans shrink by up to 92%; text reports barely move, whatever level you pick.
