About this tool
Plain language PDF commands reads sentences such as making a file smaller and dropping a page. A built-in parser covers sizes, ranges, rotate, merge, split, grayscale, page numbers, watermarks, and a password request. The password step is shown and then refused, because this version cannot encrypt. If the sentence is not recognised and the browser has an on-device prompt API, the page says so and still does not call a cloud model. You always see numbered steps and press Run. Edit returns you to the sentence. Closing the tab drops the file. The plan is steps only.
Plain language PDF commands stays on this device. The download is the copy you keep, and Weesize does not store a second one. Close the tab when you are finished and the bytes are gone.
- No upload: the sentence is parsed here, and the file is not sent out to be understood.
- Speed: the file does not travel to a server and back, so the wait is only the work itself.
- Quality: the original is kept when the new file would be worse or is not actually smaller.
