Make your photos and graphics smaller so pages load faster and files are easier to share. Compress several images at once and download them individually or together as a ZIP file.
Your images never leave your device. Compressing also removes camera data such as location (EXIF) from the saved copy.
How to use the Image Compressor
- Drop your JPG, PNG or WebP images onto the box, or click it to choose files.
- Adjust the quality slider. Around 70 to 80 percent usually looks the same as the original at a much smaller size.
- Optionally choose an output format or a maximum width to shrink large photos further.
- Compare the sizes, then download each image or all of them as a ZIP.
Getting the smallest file without losing quality
JPG and WebP are lossy formats, which means a little detail is traded for a much smaller file. WebP usually gives the smallest result at the same visible quality. PNG is lossless, so recompressing a PNG saves less. If the picture is a photograph, converting it to JPG or WebP will shrink it far more.
Large photos from modern phones are often 4000 pixels wide or more, far bigger than most websites need. Setting a maximum width of 1600 to 2000 pixels can cut the file size dramatically with no visible difference on screen.
PNG images with transparent areas will get a white background if you convert them to JPG, so choose WebP or keep PNG if you need transparency. If an image is already well optimized, the tool keeps your original file rather than making it bigger.
Frequently asked questions
Are my images uploaded to a server?
No. Compression happens on your device, in your browser. Your images never leave it.
Does compression reduce quality?
JPG and WebP compression is lossy, but at moderate settings the difference is rarely visible. Try 75 percent and compare.
Why is my compressed file not much smaller?
The image may already be well compressed, or it may be a PNG. Try WebP or JPG output, lower the quality or set a smaller maximum width.
Is camera data removed?
Yes. Saving through the browser removes metadata such as location, camera model and date, which is also good for privacy.
