Overview

Compress images when uploads, email, or page weight limits require smaller files. The Image Compressor adjusts quality and encoding while you preview tradeoffs.

Lossy compression affects fine detail in photos. For graphics with text, prefer higher quality settings and inspect zoomed regions before publishing.

Combine compression with Resize Image when dimensions are also too large — resizing first often saves more bytes than quality reduction alone.

How to choose

Smaller file for web or email → Image Compressor.
Many files at once → Bulk Image Compressor.

Frequently asked questions

Will compression remove transparency?

PNG and WebP transparency can remain if you use formats that support alpha.

Are images uploaded?

No. Everything stays on your device.

What quality setting should I use?

Start around 80% for photos and adjust while comparing file size and visual quality.
