Compress a PDF

Make a PDF smaller for email or upload. Images above 225 ppi are resampled to 150 ppi JPEG and unused objects are removed, the same as Reduce File Size in the app.

Choose PDF files or drop them hereProcessed in this browser with the Docura engine. Nothing is uploaded.

Frequently asked questions

Are my files uploaded?

Nothing is uploaded: the Docura engine runs inside this browser tab, so the file never leaves your device.

Why did my file barely shrink?

PDFs that are mostly text are already small; the savings come from large photos and scans.
