Can the Windows app process a folder at once?

Yes. Add intentionally selected files or a folder to one task queue, then set shared format and processing choices.

Why might a compressed image not be smaller?

Image content, existing encoding, and target settings affect the result. With Skip larger outputs on, a candidate that is not smaller can be left unwritten.

Are images uploaded during batch processing?

No. Import, conversion, compression, and output happen locally.

How to batch-compress images on Windows

ImgConvert processes the images or folders you intentionally choose on your Windows device instead of uploading them to a web service.

Steps

Add files or a folder to the task queue.
Choose JPEG, PNG, WebP, or AVIF as the output format.
Adjust quality or lossless mode for the job.
Confirm the directory and keep Skip larger outputs on when useful.

Notes

Results depend on image content, target format, and encoder settings; no setting can guarantee every image will be smaller.

Common question

You can process intentionally selected files or folders in a batch, entirely locally.
