How do I use Compress to 100 KB?
Compress toward a 100 KB maximum by selecting images and running the preset. Check the measured output size; enable smaller dimensions if the result is over target.
- Choose your JPG, PNG, or WebP images. Processing stays in this browser.
- The 100 KB target is already selected. Choose an output format and enable smaller dimensions only if you want them.
- Compress your images and check the measured size. Download the results that meet your needs.
Still JPG, PNG, and WebP images are supported. Each image can be up to 25 MB, 24 megapixels, and 8,192 pixels on either side. Your original file is never changed.
What should I know before using this tool?
Is 100 KB guaranteed?
The target is a maximum, not an exact size. 100 KB means 100,000 bytes. If the image cannot fit with your settings, the result clearly says Over target. Allow smaller dimensions or choose another format and try again.
Will my image dimensions change?
Dimensions stay unchanged unless you enable Allow smaller dimensions if needed. If enabled, the compressor can reduce width and height together to help reach the target.
Why isn't my PNG getting smaller?
PNG uses lossless compression and does not have a lossy quality slider here. Re-encoding an already optimized PNG can make it larger. WebP can give a smaller result while retaining transparency; JPG is suitable for opaque photos.
Does compression remove metadata?
Images that are re-encoded through the canvas do not carry their original EXIF metadata. If a file already meets the target and uses the selected format, it is returned unchanged, including its metadata.
Where can I learn more about image formats and browser tools?
JPEG uses lossy compression; PNG supports lossless compression and transparency. Choose a format that fits the image and where you will use it. MDN: Image file type and format guide.
WebP supports lossy and lossless compression, as well as transparency. Actual output size depends on the image and encoder settings. Google: WebP format overview.
