Work with PDFs.
Keep the file with you.

Interleaf is a browser-based PDF workspace for the document jobs that happen before you hit send. Open a file, shape its pages, and export the result without uploading it.

Why browser-local matters

The app reads and changes your file on your device. It does not upload the document to a server, and it does not need an account, ads, tracking, analytics, or cookies to do its job.

That keeps the boundary simple. A contract, scan, or form can stay in the browser while you work on it.

What Interleaf is today

Today, Interleaf focuses on browser-local PDF work. It can open PDFs and PNG/JPEG images together, add files later, let you review, select, reorder, rotate, and remove pages, export pages as images, open password-protected files, and losslessly compress an untouched PDF. That is the current scope.
