Start with dimensions
Large camera photos often stay heavy even after quality changes. Reducing a 4000px photo to 1600px or 1200px can remove far more weight than a tiny quality tweak.

Best use
A 100KB target depends on the original image, format, dimensions, and detail. Photos usually shrink best as WebP or JPEG.
How to compress an image toward 100KB
- Add your JPG, PNG, or WebP image.
- Start with WebP output and a quality setting around 70-80%.
- Lower the max width or max height if the file still needs to be smaller.
- Download the result, then repeat with a lower quality value if needed.
Pick the right format
WebP is usually a strong default for web uploads. JPEG works well for photos without transparency, while PNG is best when transparent edges matter.
100KB compression FAQ
Can every image be compressed to exactly 100KB?
No. The final size depends on image detail, dimensions, and format. This tool gives you the controls to move toward that target without uploading the file.
Is WebP better for reaching 100KB?
Often, yes. WebP usually gives smaller web files than PNG and can beat JPEG for many images while keeping good visual quality.
Are my images sent to Pixwright?
No. Compression runs in your browser tab using local canvas APIs.
