Shrink JPG, PNG and WebP images without uploading them. Compress up to 50 photos at once, resize them, and convert between formats.
Settings
70–80 looks the same as the original for most photos.
Before and after
Drag across the image or the slider to compare.
How to compress images
Drop your photos onto the box, choose a quality and output format, and each image is compressed on your device in a second or two. Use the before-and-after slider to check the result, then download images one by one or all together as a ZIP.
For websites, 1920 px wide at quality 75 in WebP is a good default. Smaller images load faster, which improves your search ranking and saves visitors’ mobile data.
Frequently asked questions
Are my images uploaded?
No. Images are decoded and re-encoded by your own browser. They never leave your device, so private photos and documents stay private.
Which format gives the smallest file?
WebP is usually 25–35% smaller than JPG at the same visual quality and works in every modern browser. Use JPG when a website or app doesn’t accept WebP.
Why did my PNG barely shrink?
PNG is lossless, so re-saving it can’t throw away detail. For photos saved as PNG, convert to JPG or WebP for savings of 70–90%. Keep PNG for logos, screenshots and images with transparency.
Does compressing remove photo location data?
Yes. Re-encoding drops EXIF metadata such as GPS location, camera model and date taken. The photo’s rotation is applied first, so it still appears the right way up.
