Frequently Asked Questions

Are my files uploaded or stored on any server?

No files are uploaded to any server. All processing for the image resizer, PDF designer, and invoice creator occurs locally in your browser using Web APIs. Your files remain on your device at all times.

What is the maximum file upload size for the image resizer?

There is no server-side upload limit because processing happens entirely in your browser. Practical limits depend on your device’s available RAM and CPU. Most users can process multi-gigabyte images without issues.

Can I use the invoice generator to prepare tax-compliant documents?

Yes. The invoice creator includes built-in VAT, service tax, and discount calculations that update in real time. You can toggle per-item taxes and customize the currency symbol to generate professional invoices.

How does the PDF Designer handle formatting?

The PDF tool uses an interactive Markdown composer. Standard Markdown syntax (headings, lists, bold text, code blocks) is translated directly into vector coordinates inside a downloadable PDF document.

Is there any cost, watermark, or hidden pricing tier?

Our basic tools are completely free to use without watermarks. We offer transparent premium tiers for users who need advanced features, larger file uploads, and faster batch processing.

What browsers are supported?

The tools work on all modern browsers including Chrome, Edge, Firefox, Safari, and Opera. For the best experience, use the latest version of your preferred browser. Internet Explorer is not supported.

Does this work on mobile phones and tablets?

Yes, the tools are fully responsive and work on mobile browsers. The interface adapts to smaller screens with a bottom tab navigation and touch-friendly controls. Performance depends on your device’s RAM and CPU.

What happens to my data when I close the browser?

All processed files are cleared from memory when you close the tab or browser. We only store harmless preferences like your dark mode choice and newsletter subscription status in local storage — no documents, images, or personal data are retained.

Can I use these tools for commercial purposes?

Yes! Free users can use them for standard tasks. Premium subscribers unlock full commercial rights and high-volume limits for corporate workflows.
