EzPDF is a free suite of PDF tools that run entirely in your browser. Merge, split, compress PDFs, and convert between images and PDF — without ever uploading your files. Every operation happens client-side using pdf-lib and pdfjs. There are no servers processing your documents, no accounts to create, and no limits on file size. Your files stay on your device the entire time.
