Target-size behavior
The 500KB target is useful for large photos where visual quality should remain higher.
It gives the browser more room than 100KB or 200KB, so dimension reduction is less aggressive.

- 2Select output format.
- 3Compress toward 500KB and download.
Privacy and limits
- Exact byte size can vary after browser encoding.
- Large panoramas may still exceed the target.
- Images remain on your device.
Common use cases
- Hero photos for websites
- Marketplace listing images
- Large email attachments that need a reasonable cap
Format notes
- WebP often keeps photo detail well at this size.
- JPG is a safe compatibility format.
- Very large panoramas may still need manual dimension reduction.
Original test sample
- Try a 2400px max width for a large photo and compare output around 500KB.
- Use 500KB instead of 100KB when the image contains product details or text.
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.
