Is BulkIt completely free to use?
Yes! BulkIt is 100% free with no hidden fees, no registration required, and no watermarks. We believe image compression should be accessible to everyone.
Are my images uploaded to your servers?
Absolutely not. All image processing happens entirely in your browser using client-side JavaScript. Your images never leave your device, making BulkIt the most privacy-friendly image compression tool available.
What image formats are supported?
BulkIt supports JPG, PNG, WebP, and GIF input formats. Output is optimized WebP for best compression, or PNG when transparency needs to be preserved.
