Shrink your PDFs to send them without trouble
Many official forms, upload platforms and email services limit the size of the files you can attach. Compressing a PDF reduces its weight by optimizing mainly the embedded images and the document's internal data, so it stays readable but takes up far less and you can send or upload it without it being rejected.
The biggest savings come from PDFs that contain scans or many photographs, which tend to be the heaviest. A multi-page scanned document can go from tens of megabytes to a comfortable size for email or for an e-government portal that imposes a strict maximum.
In DocuMixa compression runs directly in your browser, so the PDF is not uploaded to any server: your contracts, invoices or personal documents never leave your device. This is especially important with sensitive information.
You can choose the compression level based on your priority: more reduction to meet a tight limit, or more quality when the document must print at good resolution. If the PDF was already optimized, the tool tells you so you do not lose quality unnecessarily.
