PDF Pipeline
Chain multiple PDF operations in one workflow
All processing happens in your browser. Files never leave your device.
Hoe te gebruiken
Upload one or more PDF files by clicking the upload area or dragging files onto it. Then build your processing pipeline by adding operations: merge multiple files, extract specific pages, rotate pages, add page numbers, apply a text watermark, or convert pages to images. You can reorder operations with the arrow buttons and configure each one individually. Use the Presets tab for common workflows like "Print Ready" or "Watermark All", or save your own configurations as templates for reuse. Click Process to run all operations in sequence. The result downloads as a single PDF, or as a ZIP file when converting to images. All processing runs entirely in your browser.
Voorbeelden
Prepare a report for distribution
Upload your report chapters, merge them into one PDF, add page numbers in "1 / 10" format at the bottom center, then apply a "DRAFT" watermark diagonally across every page. One click produces the final document.
Extract and convert pages to images
Upload a presentation PDF, extract pages 1-5, then convert them to high-quality PNG images. Download all five images in a single ZIP file for use in slides or social media.
Stamp confidential documents
Upload a contract PDF, apply a "CONFIDENTIAL" watermark with 20% opacity in the center, then add page numbers at the bottom right. Save this configuration as a template to reuse on future documents.
Veelgestelde vragen
Are my files uploaded to a server?
No. All PDF processing runs entirely in your browser using WebAssembly and JavaScript. Your files never leave your device and are not sent to any server. This tool works offline once the page has loaded.
Can I save my pipeline configuration for later?
Yes. After configuring your operations, go to the Templates tab, enter a name, and click Save. Your template is stored in your browser's local storage and will be available the next time you visit. You can also use the built-in presets for common workflows.
Does the order of operations matter?
Yes. Operations execute top to bottom. For example, if you extract pages first and then add page numbers, only the extracted pages get numbered. If you add page numbers first and then extract, the numbers reflect the original document. Use the arrow buttons to reorder operations.
Why must "convert to images" be the last operation?
Converting to images produces PNG or JPEG files, not a PDF. No further PDF operations can be applied after conversion. If you need to modify the PDF first (rotate, watermark, extract), add those operations before the conversion step.
Is there a limit on file size or page count?
There is no hard limit. The practical limit depends on your device's memory. Modern devices can handle PDFs with hundreds of pages and tens of megabytes without issues. Very large files (100+ MB) may take longer to process.
