The image compressor for everyday JPG photos
This is the site's general image compressor, built for the most common case: a JPG photo that is larger than it needs to be. Choose a JPG, set the quality slider, and the tool re-encodes the photo and shows the before and after file sizes, so you can download only when the saving looks worth the quality trade. The JPG compressor handles photos one file at a time.
Where JPG compression pays off
Photos from phones and cameras are usually exported at high quality settings that web pages, emails and listings do not need. Dropping the quality moderately often cuts the file size sharply while the photo still looks the same at its display size, which helps pages load faster and keeps uploads under attachment and platform limits.
Good to know
JPG compression is lossy: lower quality means smaller files but increasingly visible artifacts, especially around sharp edges and text in the image. Your original file is never changed, so you can run the tool again at a higher quality if the first result looks too rough.
Frequently asked questions
Can I compress a JPG to an exact size in KB?
No. The quality slider controls the compression applied, and the final size depends on the photo's content. If it is still too big, lower the quality further or first reduce dimensions with the Image Size Reducer.
What quality setting should I start with?
The slider starts at 80, a sensible first try: a clear size saving with artifacts hard to see at normal sizes. If the saving is small, step down gradually rather than jumping very low.
Are my photos uploaded to a server?
No. Files are processed in your browser and never sent to the site's server. The photo stays on your device from selection to download, and the original is left exactly as it was.
