Frequently Asked Questions
Everything you need to know about privacy, security, and offline processing.
Are my images uploaded to any remote server?
No, absolutely not. All rendering, decompression, metadata removal, and format encoding execute entirely within your browser sandbox via HTML5 OffscreenCanvas and WebAssembly.
What sensitive metadata is stripped during conversion?
When "Strip EXIF" is enabled, camera serial numbers, GPS latitude/longitude, timestamp logs, aperture settings, and thumbnail caches are completely purged during pixel rebuilding.
Is there a batch file limit or subscription fee?
PrivToolbox is free for individual batch usage. Processing happens locally on your machine, so there are no cloud queue restrictions or hidden bandwidth paywalls.
