About SleekKitBox
SleekKitBox is an independent web project offering PDF utilities, an invoice generator and fillable invoice and document templates. There is no account to create or software to install. Some features send files or form values to our server for processing; see the Privacy Policy for details.
Why this site exists
Most online PDF tools are either subscription products, loaded with intrusive ads, or require an account before you can do anything. We wanted a straightforward alternative: tools that load quickly, do one job well, and let you download your results. Advertising helps support free access to core tools.
What you can do here
- PDF tools — watermark, merge, split, compress, protect, unlock, rotate, PDF-to-image and remove pages.
- Invoice generator — create invoices and download PDF copies. Invoice history and client details are stored with the current browser session and can be cleared from the history section.
- Invoice & document templates — 22 fillable templates covering invoices, receipts, credit/debit notes, trade documents, rental forms and finance models, each with live calculation and PDF download.
- Everyday & utility tools — QR codes, unit and date calculators, JSON formatter, color converter, timezone converter, word counter, password generator, UUID generator and Base64.
How we handle your files
- PDF tools & watermarking — files are processed server-side and temporary uploads are subject to the cleanup process described in our Privacy Policy.
- Invoices — invoice and client details are stored in the application database under your browser session so you can reopen recent invoices; use the history control to clear those records.
- Feedback & custom template requests — attachments you send us are stored on our server so we can actually review them; they are removed when you ask us to delete them or when we delete the related request.
- Google AdSense is loaded after page load. See the Privacy Policy for information about third-party processing and the consent configuration that must be checked for your region.
About the guides on this site
Our guides explain how the tools and templates work and discuss common use cases. Legal, tax, financial and safety topics are general information, not professional advice; requirements vary by location and transaction. Verify current rules with official sources or a qualified adviser before relying on a template.
