Compress an image

No. Your browser opens each image and compresses it on your device. No image or file name goes to our server or to anyone else. The encoders load from yorkvault.com the first time you add an image. After that, you can turn off Wi-Fi and the tool still works.

Choose Target size, type 100 and choose KB. Then add the images. For each one, the tool tries lower quality settings until the file fits. If even a low quality is too large, it makes the image smaller in pixels and tries again. The file is never larger than the size you set. Forms for jobs, visas and exams often set a limit between 20 KB and 240 KB.

JPEG and WebP compression removes detail that is hard to see. At 70 to 80% quality, most photos look the same at normal size, and the file is much smaller than the photo from the phone. Below about 50%, you can see blocks and smeared colors. Use Compare to check the copy at 100% before you download it.

For photos, WebP is smallest. Google measured WebP files at 25 to 34% smaller than JPEG files of the same quality. JPEG opens in every app and on every website. PNG is lossless, so it is right for screenshots, logos and text, but it makes large files from photos. Fewer PNG colors make a much smaller file.

A PNG keeps every pixel, so lossless compression can only find a better way to store the same data. That saves less than lossy compression. To save more, choose 256 colors or fewer under PNG colors, which works well for screenshots and graphics. For a photo, choose JPEG or WebP.

No. The copy has no EXIF, XMP or IPTC data, so it holds no location, date, camera model or serial number. That also makes the file a little smaller. To see what a photo holds before you share it, use the location and metadata remover on this site.
