About JPG Compressor

JPG Compressor re-encodes your photos at a lower quality setting to shrink file size — the same lossy compression trick every photo editor uses, just automated and instant. JPG (also written JPEG) is the standard format for photos, and it tolerates real quality reduction well: dropping from 100% to 80% quality is rarely visible to the eye, but can cut file size in half or more. Use the quality slider to trade size for sharpness — lower for web thumbnails, higher for anything printed or zoomed in. Everything happens locally in your browser, so your photos are never uploaded anywhere.

How to compress a JPG

  1. 1

    Add your JPGs

    Drag and drop your JPG or JPEG photos, or click to browse. You can add several at once.

  2. 2

    Pick a quality

    Use the slider or a quick preset — lower quality means a smaller file. It recompresses automatically as you adjust it.

  3. 3

    Download

    Save each photo individually, or download every compressed file at once as a .zip.

FAQ

Will compressing my JPG lose quality?
Yes, a little — JPG compression is lossy by nature. At the default 80% quality the difference is rarely visible; drag the slider higher if you want to be extra safe, or lower for the smallest possible file.
What's the difference between JPG and JPEG?
None — JPG and JPEG are the same format under two different file extensions. This tool accepts both.
Are my photos uploaded anywhere?
No. Compression runs entirely in your browser — your files never leave your device.
Is there a file size limit?
Each file can be up to 25MB, and up to 20 files per batch, to keep things reliable on mobile browsers.
