How to compress images without losing visible quality
Pick your images, choose a quality (70–80% is usually indistinguishable from the original) and press Compress images. You see the size before and after for every file, and a ZIP of everything when you process several at once. If a file is already optimal, your original is kept instead of making it bigger.
Are my images uploaded?
No. Compression happens inside your browser using your own device. Files never reach a server.
Which format is smallest?
WebP is usually smallest and keeps transparency. JPG is best for photos that need to work everywhere.
Why did a PNG become WebP?
In Smart mode PNGs become WebP, which is typically far smaller and still supports transparency. Choose JPG or WebP explicitly if you prefer.
