OmniPDF is a batch PDF processing tool. Select multiple files and use shared settings for compression, watermarks, passwords, or page organization. You can also combine several operations into a workflow to reduce repetitive processing and setup. Organize contracts, application documents, reports, and scanned files. Preview the results in the app and review changes before exporting or sharing. 【Batch Processing】 • Compress multiple PDFs with a target file size. • Find and permanently remove searchable sensitive text across multiple PDFs. • Add the same watermark or page numbering to multiple PDFs. • Set, change, or remove passwords required to open multiple files. • Check page orientation, remove blank pages, trim page margins, or adjust paper size. • Remove file metadata and annotations, or make editable content a fixed part of the page. 【Combine Multiple Steps】 • Choose several tools and set their execution order. • Combine compression, sensitive text removal, and watermarks in one workflow. • Save workflows you use frequently and reuse them later. • Review the results, then continue with other operations or export. 【A Complete PDF Toolkit】 • Merge, split, delete, extract, duplicate, and reorder pages. • Rotate and trim pages, insert pages, and replace pages. • Scan documents, turn images into PDF files, and export PDF pages as images. • Add text, annotations, signatures, date stamps, and stamps. Fill existing form fields. • Draw rectangles over areas to permanently remove sensitive content. 【Optional PDF Inspection】 • Check file size, page orientation, blank pages, password protection, annotations, form fields, and metadata. • Choose which items to process based on the inspection results. • Inspect first if needed, or choose a tool and start processing directly. Processing and result previews are available in the app. Exporting or sharing processed files requires an in-app purchase. OmniPDF — one batch of files, multiple steps, one workflow.
