Compress JPG online — reduce JPEG size
Built for JPEG/JPG photos from phones, cameras, and social exports. When the file is too heavy, upload forms, inboxes, and shop backends reject it. Adjust quality here, compare the before/after look and size, then download — still JPG, no format hop unless you want one elsewhere.

JPEG is already lossy, so compressing again trades a bit more detail for bytes. For portraits, landscapes, and product shots, quality around 75% is often invisible to the eye while the file shrinks a lot.
If the photo is 4000+ pixels wide, resizing before compressing usually beats dragging quality to the floor — a blurry 2000px image helps nobody on a webpage.
Re-compressing the same JPG over and over stacks damage. Start from the original when you can and keep a backup.
How to compress JPG
- Upload a JPG/JPEG photo

JPG compression tips
- Try 75–80% first, then nudge based on the preview.
- Skies and flat walls band first when pushed too hard — raise quality slightly.
- Already tiny JPG? Gains may be minimal; maybe you need resize instead.
- Need transparency? JPG cannot do it — use PNG or WebP.
Reference
| Input | Output | Note |

Compress JPG FAQ
- Does this change width and height?
- This page adjusts compression quality, not resolution. Use Image Resizer for dimensions.
- Colors look off after compression?
- Lossy encoding can shift gradients and shadows. Raise quality or verify colors in the preview before downloading.
- Can I output PNG?
- Use the general image compressor or image converter. This page focuses on staying JPEG.
- Why is it slow on my phone?
- Very large photos are heavy on mobile. Resize to ~2000px on the long edge first.
