Pick a level in WUJIEE Doc Tools and it steps down the embedded image DPI and quality to shrink the file. Text-only PDFs have little room; image/scan-heavy files shrink a lot — start with the middle level and step up if needed.
Compression resamples embedded images (e.g. 300→150/96 DPI) and re-encodes them, so lower DPI means blurrier images, while vector text is unaffected. Use the middle level for on-screen reading and keep 150DPI+ for printing.
Compress first, then upload. Email attachments, application portals and government systems often cap at 2MB or 500KB; WUJIEE Doc Tools compresses to your target size without sending the large file to a third party first.
Free, no watermark, no sign-up, no usage limit — unlike upload-based tools that gate high compression behind a membership.
In WUJIEE Doc Tools compression is processed locally and your data is destroyed when you close the page, so IDs, bank statements and contracts stay safe without leaving a copy on a server.
