How to compress an image
- Tap Choose images or drag your files onto the box. JPG, PNG and WebP all work, and you can add several at once.
- Choose Save as. "Same format" keeps JPG and WebP as they are, and saves PNG as WebP so it actually gets smaller.
- Set the quality. 80% is a good starting point.
- Tap Compress and compare the before and after sizes, then download the files you want.
If an image isn't small enough, compress it again at a lower quality, or resize it first with the image resizer. Smaller dimensions often save far more space than lower quality.
How much quality should you keep?
| Quality | Typical saving on a phone photo | Best for |
|---|---|---|
| 90% | 30–50% | Images you'll print or edit |
| 80% | 50–70% | Websites, email, most uploads |
| 60–70% | 70–85% | Strict upload limits, previews |
These are rough guides. Photos with lots of fine detail compress less; simple images with plain areas compress more. The tool shows the exact result for each file, so there's no guessing.
Why compress images?
- Upload limits. Many forms cap files at 1–2 MB, while phone photos are often 3–8 MB.
- Faster websites. Smaller images make pages load faster, which visitors and search engines both notice.
- Email and messaging. Smaller attachments send faster and fit within size limits.
- Storage. Compressing large photo collections frees space on your phone or cloud storage.
Privacy bonus: location data removed
Photos from phones usually carry hidden metadata, including the camera model and often the GPS location where the photo was taken. Because this tool re-encodes the image, that metadata is removed from the compressed copy. That's worth knowing before you post photos publicly.
Nothing is uploaded
