How to Compress JPEG Photos

1Upload JPEG
Select your JPG/JPEG photos.
2Choose Quality or Target KB
Set quality slider (e.g. 80%) or enter an exact target size (e.g. 100KB).
3Download Compressed JPEG
Save your lightweight JPEG image instantly.

Target File Size (KB): Automatically tunes compression to hit your target file size.
Strip EXIF Metadata: Removes embedded GPS coordinates and camera information.

Target Size Mode
Specify an exact target file size in KB for strict upload portals.
Split Screen Inspector
Drag Before vs After slider to inspect visual sharpness in real time.
EXIF Data Removal
Strip camera settings and GPS metadata for privacy.
Local Web Worker Engine
Off-thread compression prevents browser freezing.

Camera EXIF metadata contains embedded GPS location tags, camera serial numbers, and thumbnail caches that add unnecessary kilobytes to JPEG images.

Because it was already compressed. JPEG discards detail on every save, and a file that has already been through that once has little redundancy left to remove — you pay a second round of artifacts for a small saving. If a photo is already a modest-sized JPEG, the effective lever is dimensions, not quality: resize it to the size it will actually be displayed at and the file gets dramatically smaller with no visible penalty.

You are told, rather than quietly handed something that misses it. Target mode works by encoding, measuring the real result and adjusting, and for some images there is no setting that reaches an aggressive target without destroying them — a detailed 12-megapixel photo will not become 20 KB and still be a photo. In that case the closest achievable result is returned along with a notice saying the target was not met, so you can decide whether to loosen the budget or reduce the dimensions first.

Progressive encoding stores the image in successive passes, so a viewer sees a full-size rough version almost immediately and it sharpens as the rest arrives, instead of the picture painting downward from the top. On a slow connection that feels considerably faster even though the total bytes are similar — occasionally slightly smaller for large photos. For small thumbnails it makes no perceptible difference and is not worth thinking about.
