Image Compressor
An assistant-style compressor that analyses your image, recommends a compression level, and lets you preview the result before downloading — all processed privately on your device with the canvas API.
Examples
2.4 MB JPG
~480 KB JPG (80% smaller)
How it works
The Image Compressor analyses your image and chooses a balanced quality setting that reduces file size without making visible damage obvious. For photos, it prefers JPG and WebP encoding strategies that preserve detail while cutting bytes.
Compression works by removing data the eye is least likely to notice, then recompressing the remaining pixels. The preview shows the file size before and after, so you can confirm the image still looks right.

How to use Image Compressor
Why use this tool
Frequently asked questions
Upload the image, then lower the quality slider until the preview shows a file size near 100 KB. The tool keeps the image local and shows the expected savings in real time.
Yes. The compression happens entirely in your browser using the canvas API, so your image never leaves your device.
Some quality is traded for a smaller file, but the tool recommends a balanced setting and lets you preview the result before you download.
Use JPG or WebP for photos and complex images. WebP usually gives the smallest files with good quality, and JPG is a safe fallback for wide compatibility.
