Built around a task
Put a few PDFs together, take out selected pages, or turn images into a document. For images, convert formats, reduce file size or limit the longest edge. Other image tasks remain available in the batch workspace.
Each tool explains what it does, what it does not do, and what you should check before downloading. There are no claims of guaranteed savings or perfect results.
Your browser does the work
Your selected files are processed in browser memory. This site has no file-upload endpoint, account system or cloud drive. Download results before leaving, refreshing or closing the workspace.
Original files are not overwritten. A new output can change encoding, metadata or document structure. Check important results before relying on them.
English first, Chinese alongside
Tools and information pages have separate English and Simplified Chinese addresses. The language control keeps you on the same kind of page. Within a workspace, switching languages keeps the current files and settings.
