Questions & Answers

As answered by people managing Sli.do and PDFKit.tools.

What makes your product unique?

PDFKit.tools's answer:

PDFKit focuses on everyday PDF jobs that come up during real document work: compressing files, merging documents, splitting pages, converting PDF and image formats, rotating pages, deleting or reordering pages, adding watermarks or page numbers, extracting text and tables, filling forms, protecting files, and unlocking PDFs when the user has the right password.

The main difference is convenience. PDFKit keeps practical PDF workflows in one browser-based toolkit instead of forcing people to jump between separate tools for each small task.

Why should a person choose your product over its competitors?

PDFKit.tools's answer:

Choose PDFKit when you need quick PDF cleanup or conversion without opening a heavy desktop editor or creating an account for a simple job. It is useful for upload limits, email attachments, application documents, invoices, reports, scans, and everyday office workflows.

Dedicated desktop tools may still be better for complex editing, legal signing, advanced OCR review, or sensitive internal documents. PDFKit is built for fast, practical PDF tasks in the browser.

How would you describe the primary audience of your product?

PDFKit.tools's answer:

PDFKit is mainly for students, office workers, admins, freelancers, consultants, HR teams, creators, and small businesses that handle PDFs regularly.

Typical users need to compress a PDF before upload, merge several files into one document, split pages, convert JPG files to PDF, extract selected pages, add page numbers, remove extra pages, or clean up documents before sharing.

Which are the primary technologies used for building your product?

PDFKit.tools's answer:

PDFKit is a browser-based web application focused on PDF and document workflows. The product is built around practical tools for compression, merging, splitting, conversion, page organization, text and table extraction, form filling, password workflows, and document cleanup.

The important technical direction is to keep the tools accessible from the browser and focused on common PDF tasks rather than becoming a heavy document editor.

What's the story behind your product?

PDFKit.tools's answer:

PDFKit was created because PDF tasks are usually small but disruptive. A person may only need to shrink a file, merge two documents, extract one page, or convert a scan, but that often turns into searching for a separate tool.

The goal behind PDFKit is to keep common PDF workflows in one practical place so document cleanup is quicker and less distracting.

Who are some of the biggest customers of your product?

PDFKit.tools's answer:

  • Students preparing application documents, assignments, and scanned PDFs
  • Freelancers and consultants sending invoices, proposals, reports, and client files
  • Office admins and HR teams cleaning up forms, records, and shared documents
  • Small businesses that need quick PDF compression, merging, conversion, and page organization
  • Creators and marketers preparing PDFs, JPG-to-PDF files, and downloadable documents

PDFKit is not positioned around named enterprise customers at this stage. It is built for individual users and small teams that need practical PDF utilities without a heavy setup.
