Bulk Image Compressor

If the total zip file size exceeds the browser limit, the file will be downloaded in parts. To do this, you need to enable multiple downloads in your browser.

For Chrome: Go to Settings > Privacy and Security > Permissions > Additional Permissions > Automatic Downloads, and allow imagetoolshub.com to automatically download multiple files.

For other browsers, please search online for instructions on enabling this setting.

To optimize image processing speed:

1. Keep your browser window open and active throughout the processing. Avoid minimizing it.

2. Stay on the processing tab, or keep it open in a side window. Switching to another browser tab may pause processing, as browsers limit resources for inactive tabs.

3. If the tool uses AI, ensure you have an internet connection to initialize AI models, even though the actual image processing doesn't require it.

4. If possible, use a dedicated monitor or split your screen to keep the processing tab visible while working on other tasks.

5. Don't put your computer into sleep mode during processing. This may pause or slow down the processing.

By following these steps, you can help maintain processing speed and avoid unnecessary interruptions.

When you select the 'Compress output image' option, processing can take a considerable amount of time for large images, such as those with dimensions of 50000x50000 pixels or larger. These high-resolution images are uncommon in everyday use. Compression of such large files typically requires extended processing, varying based on file size and your device's capabilities. Please be patient during this process.
