Frequently Asked Questions

Everything you need to know about compressing images for Australian applications.

Will compressing my photo ruin the 300 DPI quality? +

No. Dopic uses advanced algorithms to reduce file size (KB) by optimizing data encoding, not by reducing pixel dimensions. Your image retains its original resolution and 300 DPI quality, making it suitable for both digital upload and high-quality printing.

Is my photo uploaded to a server? +

Absolutely not. Dopic processes all images directly in your web browser using WebAssembly technology. Your photos are never sent to our servers, ensuring maximum privacy and security for sensitive documents like visas and driver's licenses.

Can I compress an image to exactly under 50KB? +

Yes. You can select specific target limits such as under 20KB, 50KB, 100KB, or 200KB. The tool will automatically adjust the compression ratio to meet your specified threshold while maintaining the best possible visual quality.

Does this work for PNG and WebP files too? +

Yes, Dopic supports compressing JPG, PNG, and WebP formats. Whether you need to convert a heavy PNG to a lighter JPG or optimize a WebP file, the tool handles all major formats efficiently.

Will the background color change during compression? +

No. For official ID photos requiring a white background (#FFFFFF), Dopic preserves the exact color values. This ensures your photo meets strict government requirements for passport and visa applications.
