Frequently Asked Questions

Are my private documents and photos safe with these multimedia tools?

Absolutely. ModernCalcs uses high-performance HTML5 Canvas and native file APIs that run entirely in your local browser sandbox. Your photos, pictures, PDF documents, and graphics are never transmitted to any third-party server.

How does the local image compressor work?

The compressor utilizes canvas pixel adjustments to reduce metadata size and optimize color profiles. You can select exact quality outputs (Balanced, High, Low) to reduce file sizes by up to 90% without visible pixelation.

What image formats can I convert?

You can convert between all modern high-efficiency and classic image formats, including AVIF, WebP, JPG, PNG, GIF, and even combine multiple images into a single PDF document.
