SwiftPDFLab vs BentoPDF: Two Client-Side PDF Toolkits
SwiftPDFLab and BentoPDF both process PDFs in your browser, so your files stay on your device with either tool. This balanced comparison looks at where each one excels — and where the other is the stronger choice.

- Bates numbering for legal and multi-document sets

Licensing & hosting
SwiftPDFLab is a proprietary product that is free to use as a hosted service maintained by Teamz360 LLC. BentoPDF is dual-licensed: it is available as open-source software (AGPL-3.0) that you can inspect, modify and self-host, and it also offers an optional paid commercial license for proprietary use, alongside a hosted site. Neither model is inherently more private for standard client-side operations — both process your files in the browser. The practical difference is control: choose SwiftPDFLab for a maintained hosted toolkit with measurement, annotation and redaction tools, or BentoPDF if you want open-source code you can run and extend yourself, with in-place text editing and a visual workflow builder.
The Verdict: Two Strong Tools for Different Needs
Because both are client-side, you are not trading away privacy by choosing either one. Pick BentoPDF if you need in-place text editing that reuses embedded fonts, a visual workflow builder, Bates numbering or the freedom to self-host open-source code.
Pick SwiftPDFLab if you want a single hosted editor for annotation, signatures, secure redaction and forms, plus measurement tools, OCR, bookmarks, PDF comparison and a catalogue of 100+ standalone tools — all free and private in your browser.

Is BentoPDF a client-side tool like SwiftPDFLab?
Yes. Both SwiftPDFLab and BentoPDF process PDFs in your browser using client-side technology, so for standard operations your files stay on your device with either tool rather than being uploaded to a server for processing.
What is the main difference between SwiftPDFLab and BentoPDF?
BentoPDF focuses on in-place editing of existing PDF text (reusing the document's embedded fonts), a visual workflow builder, Bates numbering, and open-source self-hosting. SwiftPDFLab focuses on a unified hosted editor with measurement tools (distance, area, perimeter), secure redaction, page labels, OCR, bookmarks and table of contents, PDF comparison, and a catalogue of 100+ standalone tools.
Does SwiftPDFLab edit existing PDF text like BentoPDF?
SwiftPDFLab's editor can edit supported existing PDF text in place — replacing text and changing font size, bold or italic where compatible font faces already exist — and also adds annotation markup such as text boxes, highlights, underline and strikethrough. It does not reflow paragraphs. BentoPDF's editor likewise edits existing text directly in the PDF, reusing the document's embedded fonts.
Which tool is more private?
Both keep processing in the browser, so neither uploads your files for standard client-side operations. Privacy is comparable for typical use. Choose based on features, licensing, and whether you prefer a maintained hosted product or software you can self-host.
Is BentoPDF open source and free?
BentoPDF is dual-licensed: open-source (AGPL-3.0) that you can inspect, modify and self-host, with an optional paid commercial license for proprietary use, and it also offers a hosted site. SwiftPDFLab is a proprietary product that is free to use as a hosted service. Both can be used free of charge.
