Does it apply the same compression level to every image?

Yes, you set one compression level that's applied consistently across the whole batch.

Will compression quality vary across different image content?

The visual impact of a given compression level can look slightly different depending on the image's own complexity and detail, which is normal for any compression algorithm.

Can I compress a mix of JPG, PNG and WebP together?

Yes, mixed formats in the same batch are compressed appropriately for their own format.

Does Batch Image Compressor upload my files to a server?

No. Batch Image Compressor runs entirely in your browser using on-device processing, your files never leave your device.
