Compress an image
Choose a JPG, PNG or WebP image, adjust quality or optional max dimensions, then download the compressed copy.
Lower quality usually reduces JPG and WebP size. PNG changes may be limited.
This browser does not report WebP output support.
Optional resize limits
Blank keeps the original width unless max height scales it down.
Blank keeps the original height unless max width scales it down.
Browser-based file processing
Files are processed in your browser. NoNoiseTools does not need to upload this image to a server for this tool.
Large files may use browser memory and may be limited by canvas or file-processing support.
Avoid uploading highly sensitive files to any online tool unless you understand how it works.
How this image compressor works
Choose a JPG, PNG or WebP image, then set a quality level and optional maximum dimensions. The tool decodes the image in your browser, draws the output to a canvas and creates a local download from the generated file.
JPG vs PNG vs WebP
JPG and WebP usually respond well to quality compression. PNG output can be useful for transparency and crisp edges, but browser canvas quality settings may not reduce PNG size much. For PNG files, reducing dimensions or converting format can make a bigger difference.
Privacy notes
The image is processed in this browser tab. NoNoiseTools does not need a server upload for this tool, and the compressed download is created locally.
Browser-side processing avoids a required upload, but highly sensitive images still need caution on any website, shared device or managed browser.
Large files may use browser memory and may be limited by canvas or file-processing support.
What this tool does not include
This tool runs without a required server upload. It does not batch-compress many files, promise lossless compression, remove metadata completely, edit image content or guarantee an exact final file size.
Key terms and assumptionsBrowser processing notes, quality settings, PNG limits, file-size comparisons and local downloads.
- Browser processing
- Images are decoded, optionally scaled down and exported in this browser tab using canvas APIs. NoNoiseTools does not need a server upload for this tool.
- Image limits
- Images over 25 MB, over 16,384 pixels on one side or over 50 megapixels are rejected for browser memory safety.
- Quality setting
- Quality applies mainly to JPG and WebP output. PNG output may not shrink much through browser canvas encoding.
- Optional dimensions
- Max width and max height scale the image down only when the original exceeds those limits; they do not upscale smaller images.
- No exact target size
- The final size depends on image content, selected format, quality, dimensions and browser encoder behavior.
- No server storage
- The tool creates a local Blob download in the browser tab and does not store image files on a NoNoiseTools server.

FAQs
Is my image uploaded?
No required upload. The image is decoded, optionally resized and exported in this browser tab, and the compressed download is created locally.
Why did my PNG not get much smaller?
PNG compression through browser canvas can be limited. Reducing dimensions or converting to JPG/WebP may reduce size more, but can change transparency or quality.
Can the compressed image be larger than the original?
Yes. Some images are already optimized, and changing format or quality can occasionally create a larger file. The tool shows a calm note when that happens.
What quality setting should I use?
Start around 80% for JPG or WebP, then lower it if you need a smaller file and the preview still looks acceptable.
Can I set an exact target file size?
No. The output size depends on image content, dimensions, format, quality and your browser's encoder.
Does compression remove metadata?
Canvas export may omit some metadata, but this tool does not promise complete metadata removal.
Can I compress multiple images at once?
Not in this version. This page compresses one image at a time so browser memory and previews stay predictable.
