File & data
Merge PDFs, reshape data files and encode text — all processed locally.
- PDF StudioSee every page of every PDF you open, drag them into order, rotate, delete, split and watermark, then export. Nothing is uploaded.
- Merge PDF FilesMerge PDFs and images into one PDF, extract or reorder pages, split into separate files, rotate scans. JPG to PDF works offline too.
- CSV to JSON ConverterConvert CSV or TSV to JSON or NDJSON and JSON back to Excel-ready CSV — quoting, commas and type detection handled correctly.
- Base64 Encoder & DecoderEncode and decode Base64 text, and turn any file into a Base64 data URI for embedding.
