JPG compression notes
This page focuses on photographic JPG input, where quality and pixel width usually control most of the final size.
It is a better fit than PNG compression for camera photos, product photos and large hero images.

How it works
- 1Select a JPG file.
- 2Tune quality or reduce max width.
- 3Download the compressed JPG or WebP file.
Privacy and limits
- The JPG is processed locally.
- Metadata may be stripped by canvas export.
- Output size varies by image detail.
Common use cases
- Reducing product photos before upload
- Preparing article images for faster pages
- Making form attachments smaller while keeping JPG compatibility
Format notes
- Lower quality removes detail and may introduce visible blocks.
- WebP output may be smaller than JPG, but JPG remains more widely accepted by older forms.
- Canvas export usually removes EXIF metadata.
Original test sample
- For a 12MP phone photo, first cap width near 1800px, then compare JPG quality 70, 76 and 84.
- If a CMS accepts WebP, test WebP quality 80 against JPG quality 76 for visible detail and bytes.
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.
