**Quick answer:** To compress images, add one or many JPG, PNG or WebP files, choose the quality and a maximum size, and download the results. Typical phone photos shrink by 60 to 90 percent when you also limit them to 1920 pixels, and the images never leave your device.

## How to use it

1. Choose or drop your images: JPG, PNG or WebP, one or many.
2. Set the quality (75% is a good start) and, if you like, a maximum width or height.
3. Press Compress images.
4. Check the before and after sizes, then download or send the results.

## Where the savings come from

Three things make an image file big: how many pixels it has, how finely it is compressed, and extra data stored with it. This tool handles all three.

- **Quality**: JPG and WebP throw away detail your eye barely notices. Between 70 and 80 percent, most photos look the same as the original at a fraction of the size.
- **Dimensions**: a 12-megapixel phone photo is 4000 pixels wide, far more than any screen shows. Limiting it to 1920 pixels often cuts the size by 70 percent or more on its own.
- **Metadata**: camera details and GPS location are removed from the compressed copy, which saves a little space and keeps where you took the photo private.

PNG files are reduced differently: their colours are mapped to a palette of up to 256, which typically halves screenshots and logos with no visible change.

## Honest results

Every result shows the size before and after and the percentage saved, and the total for a batch. If an image is already well optimised and re-saving it would make it bigger, you get the original back instead, with a note saying so.

Compressed images are new files; your originals are not touched. Keep the originals if you might need full quality again later.

## Pick the right format

| Format | Best for | Notes |
| --- | --- | --- |
| JPG | Photos | Opens everywhere; no transparency |
| WebP | Photos and graphics on websites | Usually 25–35% smaller than JPG; supports transparency |
| PNG | Screenshots, logos, text | Sharp edges, transparency; large for photos |

## Private and fast

Images are compressed by your own browser, in a background worker, so nothing is uploaded and even a batch of fifty photos is done in moments. That also means there is no queue, no daily limit and no account.

Sending photos to someone in full quality instead? You do not need to compress at all: [send the originals free](https://sharelargefilesfree.com/) with a download link. See also [how to share RAW photos](https://sharelargefilesfree.com/share-raw-photos).

## Frequently asked questions

### How much smaller will my images get?

Typical phone photos shrink by 60 to 90 percent when you also limit the size to 1920 pixels, and by 30 to 60 percent with quality alone. Already optimised images shrink less.

### Will I see a loss in quality?

At 70 to 80 percent quality most people cannot tell the difference on screen. Lower settings give smaller files with visible softening.

### Are my photos uploaded?

No. Compression runs in your browser; your images never leave your device unless you choose to send them.

### Does compressing remove location data?

Yes. Compressed copies do not keep EXIF metadata such as GPS location or camera details.

### Can I compress many images at once?

Yes. Add as many as you like, then download them together as a ZIP or send them all with one link.
