Batch Processing FAQ
Does the batch processor upload images to a server?
No. ImgLab batch processing runs entirely in your browser. Images are never uploaded to any server.
How many images can I process at once?
There is no hard limit. The practical limit depends on your device's RAM. A few hundred images is typically fine on a modern computer.
What operations are supported in batch?
Compress, convert, and resize are supported. Apply the same settings to every image and download as a zip.
How do I download the results?
Once processing finishes, click Download ZIP. All processed images are bundled into a single zip file.
Will large images slow things down?
Large images use more memory and CPU. For best performance, keep images under 5000px on the longest side and process in groups of 50-100.
Does it work on mobile?
Yes, but mobile devices have less RAM. We recommend processing fewer images at a time on phones to avoid crashes.
