How to Compress JPEG Images Online for Free
Your JPEG images stay on your device. The browser validates each file, compresses it locally, and prepares the completed download without uploading the source.
Use our free JPEG compressor for up to five photos, choose quality from 10% to 100%, and check the selected image with a synchronized before-and-after comparison.
- Choose or drag in up to five static JPG or JPEG images.
- Select the preferred quality and start the sequential compression queue.
- Inspect the visual result and download an individual image or every result.
Choosing the Right Quality Level
Higher percentages preserve more photographic detail. Lower percentages create smaller files but can introduce visible artifacts, so choose the range that matches how the image will be used.

Frequently Asked Questions
Is the Noamax JPEG Compressor Free?
Yes. You can compress and download JPEG images without an account, credit card, daily allowance, or Noamax credit.
Are My JPEG Images Uploaded?
No. Validation, previewing, JPEG encoding, comparison, and download preparation happen locally in your browser.
Which JPEG Files Are Supported?
The page accepts static .jpg and .jpeg files up to 30 MB each, with up to five images at a time. Each image must stay within the supported pixel and dimension limits.
How Does JPEG Quality Affect File Size?
Lower JPEG quality usually reduces file size by discarding more visual information. The best setting depends on the image, so use the comparison control to inspect important detail before downloading.
Will the Default 80% JPEG Quality Cause Visible Quality Loss?
Every JPEG starts at 80% quality by default. This setting is designed to reduce file size without noticeable quality loss during typical viewing. Lower values use stronger compression and can make artifacts or detail loss more visible, especially around fine textures and sharp edges, so use the Before and After comparison when choosing a lower setting.
Can I Compress Several JPEG Files at Once?
Yes. Add up to five JPEG files and select Compress All. The browser processes them one at a time in sequence to avoid holding several full-resolution images in memory together.
Why Is My New JPEG Not Smaller?
The source may already be optimized, or the selected quality may preserve more detail than the source encoding. The tool reports the real output size and keeps the result available for comparison.
Does JPEG Compression Change the File Format?
No. JPG and JPEG files remain JPEG after compression, so the tool focuses only on reducing their file size at your selected quality.
