Questions
How much smaller will my JPGs get?
Photos straight from a phone or camera often shrink by half or more at Balanced. A JPG that was already compressed hard may barely change; then you get your original back, never a bigger file.
What is MozJPEG?
An improved JPEG encoder from Mozilla. At the same quality it makes files around a tenth smaller than the encoder built into browsers, and every JPG viewer opens them.
Are my photos uploaded?
No. Your files are processed on your device. We never upload them.
Can I compress a JPG to a specific size?
Yes. Choose Reach a file size and enter the size. The tool finds the best quality that fits, and if even the lowest is too big, it makes the photo smaller in pixels and says so.
Does it keep the photo details?
No. Compressed files leave out the date, camera, and location, which also saves space. The photo is turned upright first, so it still shows the right way up.
Can I compress PNG or WebP here?
This page takes JPG only. Use Compress PNG for PNGs, or Compress image for a mix of JPG, PNG, and WebP.
