Optimizing dozens of photos individually takes too much time. Batch photo compression allows you to drag a folder of up to 25 images and compress them simultaneously with consistent quality and format settings.
Streamlining photo workflows with batch image compression
Batch compression is essential when prepping client galleries, product uploads, or web archives. Applying one uniform quality setting across the entire set saves time and ensures predictable file weights.
How to batch compress up to 25 images in seconds
Drop your files into ImageDock Bulk Compressor, select your target quality percentage (80% is recommended for web use), and watch each image compress locally in browser memory.

Additional information about bulk image compressor
The best result comes from matching the tool to the real job rather than applying the strongest setting by default. Keep an original file, make a separate download for the destination, and review it at the size people will actually see.
ImageDock processes this workflow in the browser. That makes it practical for quick, focused work, while still leaving you in control of the file you choose to download and share.
