Frequently Asked Questions

Are my photos uploaded to your servers?

No, never. The entire compression process occurs locally in your browser sandbox using HTML5 Canvas. Your original files are never transmitted over the internet, keeping your photos entirely private.

How do I compress HEIC photos from my iPhone?

Simply drag and drop your .heic or .heif images into the dropzone. Our compressor automatically loads a secure web-assembly decoder in the background to translate the Apple compression format and convert it to optimized JPEG, PNG, or WebP.

What compression level should I choose?

We recommend choosing a quality level between 75% and 85%. This typically yields a 60-80% file size reduction with almost zero perceptible loss in visual quality.

Is there a file size limit?

No, since processing is done locally on your machine, there is no server-imposed file size limit. However, files over 20MB may take a few seconds to decode depending on your device's speed.
