❓ Frequently Asked Questions

Everything you need to know about privacy, compression algorithms, and format conversion.

Are my files or photos uploaded to any remote server?

No, never. InnoviTecho is built on a 100% client-side architecture. All image compression, resizing, and encoding happens entirely in your local browser memory using HTML5 Canvas and WebAssembly. Your photos never leave your device.

Which format provides the smallest file size: WebP, JPEG, or PNG?

For photographic images, WebP provides 25% to 34% smaller file sizes compared to JPEG at equivalent visual quality. PNG is best reserved for graphics requiring transparency or sharp geometric text.

Is there a file size limit or cost to use this tool?

InnoviTecho is completely free with no usage limits, paywalls, or subscriptions. You can compress images up to 50MB with high-resolution output based entirely on your device's available RAM.

Can I use this compressor offline or on mobile smartphones?

Yes. The tool is fully mobile-responsive and functions seamlessly on iOS Safari, Android Chrome, and desktop browsers. Once loaded, the compression algorithms execute entirely on your device without continuous server communication.
