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.
About JPG Compressor Online
Make JPEG photographs lighter while choosing how much visual detail to retain. Start with moderate quality, inspect fine text and sharp edges in the preview, and lower the maximum width if the image is larger than its intended display size.

What to know about JPG Compressor Online.
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.
