Is my photo uploaded to a server?

No. All conversion happens inside your browser using the Canvas API. Your image data never leaves your device.

Why does my HEIC file fail to convert?

HEIC/HEIF decoding depends on your browser's built-in codec support. Safari on macOS/iOS has full HEIC support. Chrome and Firefox may not decode HEIC natively — try Safari if you see an error.

What quality setting should I use?

Quality 85 is a good default — it produces sharp images at roughly 60–70% of the original file size. Lower values (60–75) shrink files more but may introduce visible artifacts on photos with fine detail.

What is WebP and why use it?

WebP is a modern image format developed by Google. It provides 25–40% smaller file sizes than JPEG at comparable visual quality, and supports transparency like PNG. All major browsers support WebP.

Can I convert HEIF files too?

Yes. HEIF and HEIC are closely related — HEIF is the container format and HEIC is the codec variant used by Apple. Both are handled the same way by the converter.

Will the converted image look different?

At quality 85 or above, the difference is imperceptible to the human eye. At very low quality settings (below 60) you may notice some compression artifacts in areas with gradients or fine texture.
