JPEG Compressor
Compress
The canvas previews the compressed result live as you adjust the settings. Click Compress for the exact size and a before/after split — drag the divider to judge the quality, then download. The original file is never modified.
Your images are processed locally in your browser and never uploaded to any server.
The .jpeg extension is the original spelling of the JPG format. The two are byte-for-byte identical. This compressor is tuned for JPEG photos: adjustable quality, batch processing, and instant size savings, all without your files ever leaving your computer.
How to use the jpeg compressor
- Drag your .jpeg (or .jpg) files into the upload area, or select them manually.
- Choose a quality level. Start at 80 and adjust based on the preview.
- Check the compressed size and percentage saved for each file.
- Download individually or as a ZIP containing every compressed image.
Frequently asked questions
Is .jpeg different from .jpg?
No. Both extensions store identical JPEG data. Early Windows versions only allowed three-letter extensions, so .jpeg was shortened to .jpg. Any tool that treats them differently is doing it wrong.
What is the best JPEG quality for websites?
Quality 75 is a good default for full-width photos; 80–85 for hero images where detail matters. Combined with sensible dimensions (most photos do not need to exceed 1920px wide), this typically yields files under 200 KB.
Can I compress JPEG without losing quality?
Truly lossless JPEG compression barely exists: savings of 5% at best. If you need a genuinely lossless reduction, converting to WebP lossless or optimizing dimensions is the better strategy; for visual quality, 85+ is indistinguishable from the original.
