Image exports are still images. PNG preserves transparency; JPG uses a solid background. Large files and batches depend on your device memory. Always preview important results before sharing.

What to know about Bulk Image Compressor.
Will compression always make my file smaller?
No. An already optimized source can produce a larger export. Reducing dimensions or quality can help, but always compare the reported output size.
Are my files uploaded for processing?
No. File contents are processed in your browser. The site, codecs and any required models still need to load over the network; local results depend on your device and browser.
