How to compress a JPG
Add your photos
Drop JPG or JPEG files here, tap "Choose images", or paste a picture with Ctrl+V.
Set the quality
75 is a great default for photos. Lower it for smaller files, or switch to a target size in KB.
Compare and save
Drag the comparison slider, then download your JPGs one by one or as a ZIP.
Smaller JPGs with MozJPEG
Most cameras and phones save JPGs at a very high quality setting, which keeps detail no one can see on a screen. Re-encoding with MozJPEG at quality 75 removes that excess while keeping the photo looking the same. Progressive encoding means the image also appears faster on slow connections.
Use the comparison slider on each result to check fine details, such as hair, foliage and text, before you download.
Resize photos for the web and email
Phone photos are often 4,000 pixels wide or more. For websites, emails and chats, set a max width of 1920 or 1280 pixels. Images are scaled down proportionally and never enlarged, so smaller photos stay untouched.
Resizing and compressing together typically turns a 4 MB phone photo into 200–400 KB.
Need a specific size?
Upload forms often ask for photos under 100 KB, 200 KB or 1 MB. Switch to Target file size and enter the limit in KB. The compressor finds the highest quality that fits, and scales the photo down if needed. For the most common case, use the 100 KB preset.
JPG or something newer?
JPG is the most compatible photo format. If the image is for a website, consider WebP or AVIF instead: choose them under Save as for files 25–50% smaller at the same quality. Our image compression guide explains when each format makes sense.
Frequently asked questions
What quality should I use for JPG?
Between 70 and 80 suits most photos. You'll rarely see a difference from the original, and the file is typically 50–80% smaller. Use 60 or lower for thumbnails, and 85–90 for photos people will zoom into.
What's the difference between JPG and JPEG?
Nothing. JPG and JPEG are two spellings of the same format. Older versions of Windows only allowed three-letter file extensions, which is why ".jpg" became common.
Why use MozJPEG?
MozJPEG is an improved JPEG encoder from Mozilla. It produces files that are noticeably smaller than standard encoders at the same visual quality, and the result is a normal JPG that opens everywhere.
Does compression remove the photo's location?
Yes, by default all metadata is removed, including GPS location, camera details and dates. Untick "Remove metadata" to keep it.
Can I make a JPG smaller without lowering quality?
Resizing is the answer. A 12-megapixel photo resized to 1920 pixels wide keeps full quality at the size it's actually viewed, with a fraction of the data. Set a max width in the settings.
