The PDF stays on your device.
Reduce a PDF's file size for email and upload limits. Basic re-saves the PDF more efficiently and keeps everything as it is. Medium and Strong turn each page into a compressed image, which shrinks scanned and photo-heavy PDFs dramatically, but the text can no longer be selected or searched. You see the new size before you download, and if a level doesn't make the file smaller, the tool tells you instead of giving you a bigger file.
Get a scanned document under a portal's 1 MB or 2 MB limit.
Shrink attachments that are too big to send.
Keep archives of scanned paperwork smaller.
Try Basic first for PDFs made from Word or other software. For scans and photo-heavy PDFs, Medium usually gives a big saving with readable pages; Strong is smallest.
Those levels turn each page into an image to save space. Use Basic if you need the text to stay selectable and searchable.
PDFs that are already compact, mostly text, can't be reduced much. The tool only offers a download when the result is smaller.
