Privacy-first
All processing is client-side. Your files never leave your device.
FAQ
Do you upload my images to a server?
No. Everything runs locally in your browser using the Canvas API. Your files stay on your device.
Can I batch convert many images?
Yes. Select multiple files and click Convert All, then download individually or as a ZIP.
Will EXIF / orientation be preserved?
Most metadata is stripped; rotate before converting if needed.
How does Target KB work?
We try quality first (binary search). If still above target and Auto-resize is on, we gradually scale down the image until we’re within tolerance.
