Compress PDF
Shrink scanned or photographed PDFs. Text files barely change.
A PDF made from phone photos is almost always too big to email, because each page is a full-resolution picture. Compressing re-encodes those pictures at a sensible size for reading on screen, which is where most of the weight disappears. A text-only PDF has little to squeeze and will barely shrink.
How to use it
- Open the PDF that is too large.
- Choose how hard to compress it.
- Compare the new size, then save it.
Common questions
How much smaller will it get?
It depends entirely on what is inside. A scanned document of photographed pages often drops by half or more. A PDF that is mostly text may barely change, because text takes almost no space to begin with.
Will the text stop being selectable?
No. Text stays text. Only the images embedded in the pages are re-encoded, which is where the size actually is.
Why is my file barely smaller?
Because it was already efficient. A PDF exported from a word processor holds text and vectors, not photographs, so there is nothing left to squeeze out.
