- Click Compress and check the size saved on each image.
- Use Compare to inspect before and after, then download one image or all of them as a ZIP.
Frequently asked questions
Are my images uploaded to a server?
No. The images are decoded and re-encoded by your own browser, so they never leave your device. You can even disconnect from the internet after the page loads.
What quality setting should I use?
For photos, 70–80% usually cuts the file size by half or more with no visible difference. Go lower for thumbnails, higher for images you'll print or edit again.
Why was my image marked “kept original”?
Some files are already compressed very efficiently. If re-encoding would make the file bigger in the same format, the tool keeps your original instead of giving you a worse file.
How does the target size in MB work?
The compressor lowers quality step by step (and, unless you turn it off, the dimensions) until the file fits the size you set, for example 1 MB for an upload form.
Should I convert to WebP?
WebP is typically 25–35% smaller than JPG at similar quality and supports transparency. All modern browsers display it, but some older desktop apps and upload forms still only accept JPG or PNG.
What happens to EXIF data?
By default it is removed, which also strips GPS location and camera details. Turn on “Keep EXIF” to copy it into compressed JPGs; the orientation is reset so photos still display upright.
