- Large batches depend on available device memory.
Common use cases
- Converting asset folders
- Creating backup image formats
- Preparing several files for a strict upload workflow
Format notes
- Browser support determines AVIF export.
- PNG output can be larger but preserves sharp edges.
- JPG output removes transparency.
Original test sample
- Convert a mixed image set to WebP and compare total result size.
- Use AVIF only after confirming your browser produces valid downloads.
Frequently asked questions
Are my images uploaded?
No. ImgShrink processes selected images in your browser and does not upload them to a server.
Do batch tools upload files or save history?
No. The queue runs locally in your browser, and ImgShrink does not create an account, database record or saved image history.
Why is an output format unavailable or different?
The browser controls image decoding and export support. Some browsers may not export AVIF or may flatten unsupported transparency.
Source and compatibility notes
Batch limits are based on the current local browser workflow and are set to reduce memory failures on typical devices.
