Merge, split or compress PDF files entirely in your browser. No upload, no account — your documents never leave your device.
Drag and drop PDF files below, reorder them, then merge into one PDF.
Yes. All processing happens entirely in your browser using JavaScript. Your files are never uploaded to any server.
Select the Merge tab, drag and drop your PDF files or click to upload them, reorder if needed, then click Merge & Download.
Select the Split tab, upload your PDF, choose which pages to extract (e.g. 1-3, 5, 7-9), then click Split & Download.
The compressor removes redundant metadata, optimizes structure and re-encodes the PDF. This works best on PDFs with large metadata or duplicate resources. Image-heavy PDFs may not shrink significantly.
