Why this matters
Most online compressors upload your image first. That is fine for a random product photo. It feels worse for client work, screenshots, documents, or anything personal.
Browser based compression skips that upload. The image opens on your device, gets compressed there, and downloads back to you.
How to do it
Open a local image compressor, drop your files in, choose a size if you need one, then download the result. If the tool is built properly, the file never leaves your browser.

When it is enough
For blog images, website assets, social graphics, and email attachments, local compression is usually enough. If you are processing thousands of huge camera files, a server tool may still be faster.
