Frequently Asked Questions
Is the Noamax Online Image Compressor Free?
Yes. You can compress in seconds and download instantly JPG and PNG images without an account, credit card, daily allowance, or Noamax credit.
Are My Images Uploaded to Noamax?
No. File checks, previews, compression, comparison, and download preparation happen locally in your browser. Your source and compressed images are not sent to Noamax.
Which Image Formats Can I Compress?
The online image compressor accepts static JPG, JPEG, and PNG files up to 30 MB each, with a maximum of five files at a time. Animated PNG files and other formats are not supported.
Can I Compress JPEG and PNG Images Together?
Yes. Free image compressor accepts a mixed batch and preserves each source format. Images are processed one at a time in sequence, even when you select Compress All.
Does the Image Compressor Change My Image Format?
No. JPEG files remain JPEG and PNG files remain PNG. The compressor accepts both formats in the same batch, while the format-specific pages let you work with JPEG or PNG files only.
What Does the Quality Setting Change?
For JPEG, quality controls lossy compression. For PNG, settings below 100% reduce the color palette; 100% keeps full color detail. Lower settings usually create smaller files but can make visual changes more noticeable.
Will the Default 80% Quality Setting Cause Visible Quality Loss?
Every image starts at 80% quality by default. This setting is designed to reduce file size while keeping visual differences unnoticeable during typical viewing. Lower values apply stronger image compression and can reduce quality, especially in detailed photos, gradients, and graphics, so use the Before and After comparison when choosing a lower setting.
Why Can a Compressed File Be Larger?
File size depends on image content, source encoding, format, and quality. A source that is already highly optimized can produce a result that is the same size or larger at a high quality setting.
