Is DesiToolz really 100% free with unlimited usage?

Yes, 100%! All tools on DesiToolz are completely free with zero limits, zero paywalls, and no hidden subscriptions. We build lightweight, efficient client-side and Node.js utilities that process data right in your browser without requiring costly server charges.

How are my uploaded files and data protected from leakage?

Privacy is guaranteed by architecture. All core utilities (CSV to Excel, JSON formatting, image compression, QR generation, PDF operations) run directly on your own device using client-side JavaScript, HTML5 Canvas, and WebAssembly. Your files and data are NEVER uploaded to any remote server or stored anywhere.

How does the CSV to Excel converter fix messy single-column data?

If your CSV was exported with non-standard delimiters (semicolons, pipes, tabs, carets) and is lumped into a single column, DesiToolz automatically analyzes character frequencies, detects the underlying delimiter, and offers a 1-click option to divide data into neat tabular columns or keep raw format based on your explicit consent.

How can I convert Excel spreadsheets to clean PDFs without webpage headers or upload buttons?

Our Excel (XLSX) to Clean PDF engine contains an isolated document canvas. When saving or printing to PDF, it strips out all navigation menus, upload buttons, configuration forms, and webpage chrome, exporting strictly your clean tabular report, title, and page numbering.

Do I need to create an account or provide payment details?

No account is needed. You can use every tool immediately without signing up, entering email addresses, or providing credit cards.

Can I convert very large CSV or Excel files without crashing?

Yes. Our CSV and Excel parser uses streaming browser workers and memory-optimized chunks that can handle hundreds of thousands of rows smoothly with zero browser freezing and instant XLSX file downloads.

Can I use DesiToolz tools offline without an active internet connection?

Yes! Because all 30 utilities are powered by client-side browser engines (pdf-lib, SheetJS xlsx, canvas, browser Web Crypto), once the page is cached in your browser you can run conversions, compress images, and merge PDFs even completely offline.

How does DesiToolz compare to Smallpdf, ILovePDF, or TinyURL?

Unlike legacy SaaS tools that impose daily limits, queue timers, file size caps, and watermarks unless you purchase an expensive monthly subscription, DesiToolz is 100% free, unlimited, ad-light, and guarantees strict local privacy.

What is the safe subtitle bounding box for 9:16 vertical video?

Keep all critical text between 220px from the top (below header hazard) and 420px from the bottom (above description hazard), with at least 80px left and 120px right margins.
