Frequently Asked Questions
Are my images uploaded to a server?▾
No. All processing happens entirely in your browser. Images never leave your device.
Which formats are supported?▾
Input: JPEG, PNG, WebP, AVIF, HEIC/HEIF. Output: JPEG, PNG, WebP, AVIF (with automatic fallback to WebP on browsers that cannot encode AVIF).
How many images can I compress at once?▾
There is no hard limit. Select multiple files and download them as a single ZIP. Up to ~50MB per file is recommended.
How much smaller will my images get?▾
It depends on the source and quality, but JPEG→WebP typically saves 30–60% and AVIF 50–80%.
