Drag and drop your files onto the upload area. Depending on the tool selected, you can add PDFs, images, or Office documents.
Choose your desired operation (compress, merge, split, convert, etc.) and configure the options. Then click Process to start.
Once finished, you can download the resulting files individually or all at once.
Use cases: optimize scanned PDFs, merge signed documents, split large reports by chapter, and convert office files for universal sharing.
