Compress a PDF Without Uploading It
Shrink a PDF for email or upload limits without sending the file to anyone. IYONM compresses it inside your browser, so the document never leaves your device.
0 KB uploaded. Open your browser's Network tab while you use any IYONM tool and you will see zero data leave your device.
Private compression
Reducing a file's size should not require handing it to a stranger's server. IYONM compresses your PDF locally, which is faster and keeps the contents private.
