Frequently Asked Questions
How many images can I compress at once?
There is no hard limit — you can upload and compress as many images as your browser memory allows. For very large batches (100+), we recommend processing in groups of 50.
What formats are supported?
JPG, PNG, and WebP are fully supported for batch compression.
Are my images uploaded to a server?
No. All compression happens entirely in your browser. Your images never leave your device.
Can I set different quality levels per image?
Currently the quality setting applies to all images in the batch. For individual quality control, use the standard Image Compressor tool.
