Drag PDF files here, or click to choose files from your computer.
Compression rasterizes pages (text becomes an image) — perfect for portals with size limits, not for editing later.
Nothing is uploaded. Open your browser's DevTools, go to the Network tab, and run a merge or compress — you'll see no requests carrying your files.

Frequently asked questions
How do I compress a PDF to under 200KB?
Upload your file above, check "Compress to a target size," set 200 in the KB field (or click the 200 KB preset), and click merge. The tool rasterizes each page and binary-searches image quality and scale until the result is at or under 200KB, or reports the smallest size it could reach.
Can I merge PDFs without uploading them?
Yes. This tool runs entirely in your browser using client-side JavaScript — your files are read locally and never sent to a server. You can merge PDFs without uploading them at all, which is exactly the point for anyone who cares about privacy or confidentiality.
Does this work offline?
Yes. Once the page has loaded, merging and compressing both work offline — there is no network call for either operation. The only network requests this site makes are for the page's own assets and an anonymous analytics beacon.
