Compress Image

Reduce common image sizes with local browser codecs. Process batches sequentially, optionally limit dimensions and keep the original whenever a generated file would be larger.

Questions about Compress Image

Will every image become smaller?

No. Already optimized images can be smaller than a new encoding. Premier keeps the original when the generated file is larger.

Are my files uploaded to Premier?

No. This tool processes compatible input on your device. The selected file is not sent to a Premier conversion server.

Is there a daily limit?

Premier Tools does not impose a daily conversion quota. Practical limits depend on your browser, memory and device.
