URL parameters for PDF tools document the query strings the pages already understand. /compress-pdf?target=200kb opens Compress and treats 200 KB as a goal, not a guarantee. /compress-image?target=50kb does the same for images. /compress-pdf?gray=1 starts the black and white option. /split-pdf?pages=1-3 fills the range box. /presets/ followed by an id opens Get it accepted for that record, and a draft id is refused. Controls on these pages have accessible names, and the main buttons carry data-action attributes for tests and for a future agent hook. If the browser exposes a standard way to offer tools to an assistant, the app registers compress, merge, split, presets, and the share check. The registration only opens a local page.

URL parameters for PDF tools 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: a query string only sets options in this tab.
• 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.
