Feature request: Batch image compression, quality control and AVIF support

[vibedev56]

It would be great to add three features to the image compression tool https://browserytools.com/tools/image-compression:

1. Batch image compression

   Currently, it is only possible to upload and compress one image at a time. It would be very useful to allow users to upload multiple images at once and compress them all in a single batch.

   Ideally, the tool could process all selected images and provide the compressed files for download, either individually or as a ZIP archive.

2. Compression quality control

   It would be useful to have an option to control the compression level / image quality before processing the images.

   For example, a quality slider or a percentage value (e.g. 10-100%) would allow users to choose the desired balance between file size and image quality. The selected quality setting should be applied to all images when using batch compression.

3. AVIF output format

   It would also be great to have the option to compress or convert images to AVIF format, in addition to the currently supported formats.

These features would make the tool much more convenient for optimizing multiple images and controlling the trade-off between image quality and file size.

Thanks for considering these improvements!
