Image Compressor
Compress JPEG, PNG and WebP images in bulk with adjustable quality and max size, compare before and after, and see the space saved. Nothing is uploaded.
Drop files here, or
JPEG, PNG, WebP, GIF and more. Choose several at once, up to 50 MB each.
Or paste an image with Ctrl/⌘ + V
Files are never uploaded.
Lower means smaller files but worse quality; 70–85 usually looks the same.
Your browser cannot save WebP, so only JPEG is offered.
Leave empty to keep the size. Otherwise larger images shrink, keeping their proportions, until both sides fit.
How to use
- Drop or choose one or more images (JPEG, PNG, WebP, GIF and more).
- Adjust the quality (80 by default), pick an output format if you like, or enter a max width / height to shrink oversized photos too.
- Each image shows its size before and after and the percentage saved, with a total below. Click “Compare” and drag the slider to check the quality.
- Click “Download” on each image to save it. There is no ZIP download yet, so save them one by one.
FAQ
Are my images uploaded?
No. Compression runs entirely in your browser; your images never leave your device and are not sent to any server.
Why is the compressed file larger?
The original may already be heavily compressed, or it is a lossless PNG: browsers re-encode PNG without extra optimization, so the result is often larger. The tool warns you when this happens, and “Keep original” downloads your original file instead. You can also lower the quality or switch the output to WebP.
What quality should I use?
For everyday photos, 70 to 85 usually looks identical while making files much smaller. Use a higher quality for printing or editing. For messages and web pages, combine it with a max width / height for the biggest savings.
Is the EXIF data (date taken, GPS location) kept?
No. The image is re-encoded, which strips EXIF, GPS location and other metadata; the photo is first turned upright according to its EXIF orientation. To view or remove EXIF data only, use the EXIF Viewer & Remover.
Can I compress animated GIFs?
Browsers cannot save GIF, so a GIF is saved as WebP (or JPEG) and only its first frame is kept; the animation is lost.
Are there size or count limits?
Each image can be up to 50 MB and about 50 megapixels. There is no limit on the number of images, but they are processed one at a time, so many or very large images take a while and use more memory.
