How to use Recompress a JPG
- 1. Load the JPG to shrink. Choose the .jpg file you want to make smaller. The tool decodes it right away and shows the current dimensions and preview.
- 2. Choose a new Quality level. Set the Quality slider below the image's original compression, such as 60, to force a fresh, tighter encode. Lower values cut file size further but introduce more visible blockiness around edges.
- 3. Download the re-encoded file. Compare the estimated size before and after, then download the recompressed .jpg. The dimensions stay the same; only the compression level changes.
When to use Recompress a JPG
Recompress a JPG takes a photo that's already in JPG format and re-encodes it at a new quality setting, shrinking the file without resizing it. It's the fastest fix when a JPG is bigger than it needs to be for where it's going.
- Fitting an upload size limit. A form or CMS caps image uploads at 1 MB and your camera's JPG is 3.5 MB. Dropping the quality to 60 or 50 usually clears the limit while the photo still looks fine on screen.
- Trimming a photo gallery's load time. A portfolio site serves full-resolution camera JPGs straight from an export folder. Recompressing each one at a moderate quality cuts page weight without anyone noticing a difference in the browser.
- Reducing storage costs in bulk. A shared drive full of event photos is eating into a storage quota. Running each JPG through a lower quality pass can reclaim significant space before archiving the folder.

About the Recompress a JPG tool
Recompress a JPG is a free online tool that works entirely inside your web browser. Re-encode a JPG at a new quality to shrink its file size. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.

You can shape the output with the Quality (%) setting, and the result refreshes the moment you change it. The finished file is put together in browser memory and saved with the Download button, so it never touches a server on the way to your disk.

Because nothing leaves your device, the tool is suitable for sensitive content such as internal documents, credentials or customer data. It also responds instantly, since every keystroke is handled on your own machine rather than by a remote API.
