Target-size behavior
This tool searches for a quality setting and may downscale dimensions to get closer to 100KB.
It is designed for practical upload limits, not laboratory-exact byte matching.

How it works
- 1Choose an image.
- 2Keep WebP or switch to JPG.
- 3Compress toward 100KB and download.
Privacy and limits
- Exact target size depends on image detail and browser encoding.
- The tool may reduce dimensions to approach the target.
- Very complex images may stay above 100KB.
Common use cases
- Profile photos with strict upload caps
- Application forms that reject large files
- Small document images for quick transfer
Format notes
- WebP usually gives the best chance of reaching 100KB.
- JPG may be required by some upload forms.
- Detailed photos may need smaller dimensions to fit the target.
Original test sample
- Start with WebP output for photos above 1MB, then switch to JPG if the target site requires it.
- Inspect faces and small text after compression because 100KB is a tight target.
Frequently asked questions
Are my images uploaded?
No. ImgShrink processes selected images in your browser and does not upload them to a server.
Can this tool guarantee an exact file size?
No. Target compression gets close when possible, but the final bytes depend on image detail, dimensions, format and browser encoding.
Why is an output format unavailable or different?
The browser controls image decoding and export support. Some browsers may not export AVIF or may flatten unsupported transparency.
Source and compatibility notes
This tool works in the browser, so output support depends on what your browser can read and export.
