What is JPG compression?

JPG compression re-encodes your image at a lower quality setting, trading a small, often invisible amount of visual detail for a meaningfully smaller file size, while keeping the same JPG format. JPG (or JPEG) is a lossy raster image format built for photographs. It compresses images by discarding image data that's hard for the human eye to notice, producing small files at the cost of some quality on repeated saves.

How to compress a JPG file

Choose a JPG file using the drop zone above (or drag and drop it in).
Adjust the compression level if you like, then click "Compress".
Click "Download" to save your smaller JPG file.

Why compress a JPG file?

A smaller JPG file uploads faster, loads faster on a website, and takes up less storage or email attachment space — often with no visible difference in quality.

Is this private?

Yes. This JPG compressor runs entirely in your browser using the Canvas API — your file is never uploaded to our servers, stored, or logged. Closing this tab discards everything.
