The JPEG Compressor is built specifically for .jpg and .jpeg photographs. It re-encodes the image at a smaller size while keeping skin tones, gradients, and fine detail looking natural. This is ideal for shrinking camera photos before emailing them, uploading to a website, or attaching to a form with a size limit.
Frequently Asked Questions
JPEG is a lossy format, so it responds very well to compression. The JPEG Compressor lets you cut file size dramatically while keeping photographs looking sharp.
Yes. A quality slider lets you choose anywhere from maximum compression to near-original quality so you can hit a specific target size.
Re-encoding a JPEG removes most embedded metadata such as location data, which is a small privacy bonus when sharing photos online.
This page compresses JPEG files. Compression re-encodes the image at a lower quality setting, discarding detail the eye is least likely to miss, and everything happens locally in your browser.
How it works
- Select your JPEG files — several at once is fine.
- Set the quality level and watch the estimated saving.
- Compare the preview against the original before committing.
- Download the compressed files.
Good to know
JPEG files respond differently to compression depending on their content. Photographs with smooth gradients compress well; images with sharp text or flat colour regions show artefacts sooner and are often better served by resizing or a format change.
Frequently asked questions
How much smaller will my JPEG get?
It depends entirely on the source. Photos straight from a phone often shrink by 60 to 80 percent with no visible difference; files that were already compressed once have far less left to remove.
Can I undo the compression?
No. Compression is lossy and the discarded detail is gone for good, so always keep your original file. The compressed copy is a derivative, not a replacement.
