Websites load slowly due to massive images, but cloud compressors have low file size limits.
✓ Convert heavy PNGs to WebP and scale dimensions locally without any strict file limits.
Privacy Advocates
Phone photos contain hidden EXIF data (GPS coordinates, timestamps) that cloud tools might log.

Frequently Asked Questions
Is it safe to compress private family photos here?
Absolutely. When you use Refinata, your images are processed directly by your browser's local graphics engine. Your personal photos—and the hidden GPS location data attached to them—never leave your device.
How does the HEIC to JPG converter work without uploading?
Refinata uses WebAssembly to load an HEIC decoder directly into your browser. It translates the Apple HEIC format into standard pixels locally, allowing you to save it as a JPG. No server is ever involved.
Do I lose quality when compressing images?
Our image compressor uses advanced browser-native encoding algorithms. You can visually preview the compression level before saving, allowing you to strike the perfect balance between file size and crystal-clear quality.
Can I process hundreds of images at once?
Yes! Because there is no network bottleneck (zero uploading), you can drag and drop hundreds of images simultaneously. Your computer's CPU will process them locally in a fraction of the time a cloud tool would take.
