Compress JPG Online

Shrink JPG photos in your browser: lower the quality, cap the width, compare before-and-after sizes and download a lighter file. Originals are never replaced or uploaded.

Why JPGs are heavier than they need to be

Cameras and phones save JPEGs at very high quality settings because storage on the device feels free. The weight shows up later: an email that refuses the attachment, a product page that loads slowly, a form with a 2 MB upload cap. The image compressor above re-encodes your JPG at a quality you choose — typically 75–85 for photos — and can also cap the width, showing you the exact before-and-after byte counts before anything downloads.

Quality down, dimensions only if you ask

Two levers, honestly labelled: quality trades invisible detail for size, and maximum width shrinks dimensions for screens that will never display the full resolution. Images are never enlarged, and every result is a new file, so experimenting costs nothing. If a source was already well optimised, the tool tells you when a result is not smaller rather than hiding it. Graphics with transparency belong in the sibling workflow, compress PNG, and if a form demands a specific ceiling, compress image to 200KB walks through hitting a target size.

Private by default

Your photos are decoded and re-encoded on your own device. No upload, no account, no copies left on a server.

Frequently asked questions

How much smaller will my JPG get?

It depends on the source. A camera JPG at maximum quality often shrinks dramatically at quality 80 with no visible change; an already-optimised web JPG may barely move. The preview shows the real byte comparison before you download.

What quality setting should I use?

Around 75–85 is the usual sweet spot for photos: much smaller than the original with differences that are hard to spot. Go lower for thumbnails and previews, higher for anything that will be printed or edited again.

Will compressing change the dimensions?

Only if you set a maximum width: the image is scaled down to fit and never enlarged. Leave the width unset to keep the original pixel dimensions and save space through quality alone.

What if the compressed file comes out larger?

That can happen with already-efficient sources, and the tool reports it clearly instead of pretending. Download only the results that are actually smaller, or try a lower quality setting.

Are my photos uploaded to be compressed?

No. Compression runs in your browser on files you select, and every download is a new file — your originals are never replaced or sent anywhere.
