Image Compressor — Reduce Image Size Without Uploading
Free image compressor. Reduce JPG, PNG and WebP file size right in your browser with a quality slider and live size comparison. No upload.
Runs in your browser — your data is never uploaded.
Large images slow websites and fill inboxes. Drop in a picture, choose the quality and output format, and the compressor shows the new file size and the percentage saved before you download. Compression happens locally in your browser, so your photos are never uploaded. WebP usually gives the smallest files for the web.
How to use the Image Compressor
- Choose or drop an image.
- Adjust quality and format.
- Compare sizes and download the compressed image.
