Compress JPG Images

Re-encode one JPG with adjustable compression. Stronger compression usually makes a smaller file but removes more visual detail. Pixel dimensions do not change, and target sizing is best effort.

Choose an image
Compress JPG
Choose a file to start
Upload a JPG, set the compression level or target size, then download the smaller image from the result panel.
  • Higher compression levels usually create smaller files.
  • Target size is best-effort and may not be possible at the current dimensions.
  • The result panel shows the size change before you download.
Works with JPG images.
Higher values mean smaller file sizes.

JPG Compressor Features

JPG output

JPG is widely supported for photos and sharing.

Compare sizes

See the original size versus the compressed size.

Preview the result

Review the compressed image before downloading.

Compressed filename

Downloads add a -compressed suffix to the filename.

Runs on your device

Compression runs in your browser on your device while you wait.

Compression, not resizing

Pixel dimensions stay the same. Stronger compression trades visual detail for a smaller file.

Frequently Asked Questions

The tool shows the original size, compressed size, and the reduction ratio.

The download keeps your base filename and adds a compressed suffix.

Yes. Stronger compression can remove visible detail to reduce file size. Review the result before sharing it. Pixel dimensions stay the same.

No. The pixel dimensions stay the same. This route changes compression only.

Image Tips and Ideas

Tip

Dial in the balance

Move the quality slider until artifacts are acceptable for your use. Small changes can make a big difference in size.
Tip

Keep an original copy

JPG compression is lossy, so hang on to the original if you may need full detail later.
Tip

Pick the best format

JPG works best for photos. For crisp text, logos, or transparency, PNG may be a better fit.

What JPG compression changes

JPG reduces file size by discarding some image data. At higher compression levels, fine detail can soften and blocky artifacts can appear.

When compression helps most

Compression is useful for web delivery, email attachments, and faster sharing. Preview the result to make sure it still meets your visual needs.

Reading the size results

The tool shows the original size, the compressed size, and the percentage saved so you can decide on a good balance.

Common JPG size targets

Need a fixed limit instead of a general quality pass? Try compress JPG to 100KB or compress JPG to 200KB.
