## What compression does to JPG

Re-encodes with an optimised JPEG encoder at a tuned quality and strips bulky metadata.

- **Light:** Near-lossless: re-encodes conservatively and keeps the full resolution.
- **Balanced (default):** The default: looks the same for most uses, and typically 40–70% smaller.
- **Strong:** Smallest file: lower quality, and large images are downscaled.

Need it much smaller? WebP reaches the same visual quality in a noticeably smaller file, if the place you're uploading to accepts it. [Convert JPG to WebP](https://www.converterrr.com/jpg-to-webp).

## How to compress JPG

1. **Add your JPG files.** Drag and drop JPG files onto the compressor, paste them, or click to browse. You can add several at once.
2. **Pick a level or a target.** Balanced is selected and suits most files. Choose Light to stay closer to the original or Strong for the smallest file, or set a target size or a percentage to reduce by.
3. **Compress.** Click Compress. Your JPG files are processed right in your browser, usually in seconds.
4. **Download.** Download each smaller JPG, or everything at once as a ZIP.

## Good to know

- Phones and cameras save JPGs at very high quality, so there's usually plenty of room to shrink a photo without any visible change.
- Every JPG re-save loses a little detail. Compress once, from the best copy you have, rather than re-compressing a file that was already squeezed.
- Need to meet an upload limit? Set a target size (or a percentage to reduce by) in the compressor and the photo is compressed to fit, downscaling it if it has to.
- JPG compression runs entirely in your browser with WebAssembly, so nothing is uploaded and your files never leave your device.

## About the JPG format

JPG is the most widely supported photo format. Its lossy compression makes photographs small while keeping them visually close to the original.

## Compressing JPG: frequently asked questions

### How do I compress a JPG file?

Drop the JPG onto the compressor above, keep Balanced or pick another level, and click Compress. Download the smaller JPG when it's done; it usually takes a few seconds.

### Does compressing JPG reduce quality?

A little, by design: JPG is a lossy format. Balanced is tuned to look the same for most uses; choose Light if you want to stay closer to the original.

### How much smaller will my JPG get?

Photos straight from a phone or camera typically shrink by 40–70% on Balanced. JPGs that were already optimised for the web shrink less, because there's less left to remove.

### Can I compress JPG to a specific size?

Yes. Set a target size in the compressor, or a percentage to reduce by, and the file is compressed to land at or just under it. Common sizes like 20 KB, 50 KB, 100 KB or 200 KB are listed on this page with the target preset.

### Is it safe to compress JPG files here?

Yes. JPG files are compressed inside your browser with WebAssembly and never uploaded to a server.

### Is the JPG compressor free?

Yes. Compression is free with no watermark and no sign-up, within the same daily allowance as conversions.

### Should I convert my JPG instead?

Sometimes. WebP reaches the same visual quality in a noticeably smaller file, if the place you're uploading to accepts it. The JPG to WebP converter does that in one step.
