Online tool to flatten PDF files using ImageMagick.
Our PDF Flattener is a specialized online tool designed to convert layered PDF documents into flat, single-layer files by rasterizing all elements. This process merges annotations, forms, images, and text into a unified image layer, making the PDF non-editable and secure. Ideal for finalizing documents before sharing or archiving, the tool uses ImageMagick to process PDFs with high resolution (300 DPI) and quality (90%). Whether you're preparing contracts for signing, securing sensitive documents, or ensuring compatibility across devices, this flattener provides a simple, effective solution. Upload your PDF, and download the flattened version instantly, with all interactive elements preserved as static visuals.
The PDF Flattener operates by converting the PDF into a series of high-resolution images using ImageMagick's convert command. The process begins with file upload and validation to ensure it's a valid PDF. ImageMagick then rasterizes each page at 300 DPI with 90% quality, flattening all layers, annotations, and form fields into a single image layer per page. The resulting images are reassembled into a new PDF file. This server-side processing ensures security and efficiency, with temporary files deleted after download. Note that the output is image-based, so text becomes non-searchable, but visual fidelity is maintained.
Your PDF privacy is fully protected. Uploaded files are processed temporarily on the server and deleted immediately after flattening. We do not store, share, or analyze your documents. The tool operates without user accounts or data collection, ensuring that confidential or proprietary PDFs remain secure. All processing happens in real-time with no long-term retention of your data.
