Are my files uploaded to a server?

No. This tool runs entirely in your browser — your files and text never leave your device, which makes it fast and completely private.

Why is my compressed file sometimes the same size?

If an image is already well-optimized, re-compressing can't make it smaller — the tool keeps your original in that case. Use the “Resize to” option to shrink large images further.

What's the best way to make a huge image much smaller?

Lower the quality to around 50–70% and pick a “Resize to” value like 1920px — that combination dramatically reduces size while staying sharp for screens.
