PDF Compressor
Make a PDF smaller — offline, without uploading it.
Runs in your browser — nothing is uploaded
⬒ Drop a PDF to compress
Nothing is uploaded; the file is read in this tab. Text and vector art are
never re-encoded in either mode, so the document stays selectable and
searchable.
Document
Image re-encoding 70 — lower is smaller and softer.
No size is predicted from this: pressing Compress does the work and
reports the real numbers.
An image carrying more detail than this across its page is scaled down
to it. An image already below it keeps its own size — nothing is ever
scaled up.
Output
The PDF libraries — the writer that rewrites the file and the renderer that draws the pages beside it — are downloaded the first time you drop a file, never when the page loads.
How to use
- Drop a PDF.
