The Image Compressor reduces an image file's size while keeping visual quality as close to the original as possible, using lossy or lossless compression depending on the format.
How Compression Actually Shrinks a File
Uncompressed or lightly compressed images (particularly PNGs and camera-original JPEGs) often carry far more data than is visually necessary — redundant pixel information, unnecessarily high color precision, or embedded metadata that serves no display purpose. Lossy compression selectively discards data the human eye is least likely to notice, while lossless compression re-encodes the same visual information more efficiently without discarding anything; the right choice depends on whether absolute pixel-perfect accuracy matters for your use case.
Why Compression Level Involves a Trade-off
- Light compression — minimal file size reduction, but visually indistinguishable from the original in most cases.
- Moderate compression — a good balance for most web use, substantially smaller files with quality loss that's difficult to spot at normal viewing sizes.
- Aggressive compression — maximum file size savings, but can introduce visible artifacts, blockiness, or color banding, especially in images with fine detail or gradients.
Why This Matters for Page Speed
Images are typically the single largest contributor to a webpage's total download size. Compressing images before uploading them directly improves page load time, which factors into Google's Core Web Vitals ranking signals and directly affects how quickly visitors can actually see and interact with your content, especially on mobile connections.
