About this tool
This is a real, in-browser compressor: images are decoded and re-encoded with the Canvas API, so files get smaller right on your device.
Adjust the quality to balance size and sharpness, then download. Nothing is uploaded, making it safe for personal or client photos.
How to use Image Compressor
- 1Drop in a JPG or PNG image.
- 2Move the quality slider to trade sharpness for file size.
- 3Compare the preview and the new byte size.
- 4Download the compressed image.
When you might need this
- You need to shrink photos before emailing them.
- You are speeding up a website by trimming image weight.
- You want smaller images without a cloud service.
Limitations to keep in mind
- Re-encoding is lossy; very low quality settings soften detail.
- PNG with transparency stays transparent but may grow if complexity rises.
- Already-optimized images may not shrink much further.
