BundleStamp FAQs
- Do my documents get uploaded anywhere?
- No. BundleStamp runs 100% offline on your laptop - merging, numbering, OCR and export all happen on-device. Nothing ever leaves your computer, which is exactly what confidential case files and client records require.
- What file types can BundleStamp merge?
- Folders, ZIP archives, PDFs, images, Word (.docx) and Excel (.xlsx). Word and Excel files are converted to PDF automatically, and oversized spreadsheets can be truncated to just the rows you need.
- Does it support Bates numbering?
- Yes - flexible Bates-style page numbering with custom prefix, suffix, position and zero-padding, plus auto-generated bookmarks that mirror your folder and file structure.
- Who is BundleStamp for?
- Anyone who assembles documents that have to be right: lawyers and legal teams preparing exhibits and case bundles, chartered accountants bundling statements and annexures, consultants building report packs, and businesses organizing contracts and records.
- How much does BundleStamp cost?
- It's free to install on Windows and macOS - you're billed only for the pages you export. Create an account at pdf.kras.ai to activate.
