Compress Image in Browser
Compress screenshots, blog images, and previews locally before upload or publishing.
Long-tail guide
Who this is for
Creators, students, developers, and site owners who want smaller images without uploading originals to a separate compressor.
Browser image compression is useful when you need a quick lighter copy for a page, form, README, support ticket, or social preview. The original should still be kept when quality or metadata matters.
Good use cases
Common tasks
- Reduce a screenshot before attaching it to a form.
- Create a smaller blog image before publishing.
- Resize a product preview for a landing page.
- Compare JPEG, PNG, and WebP outputs quickly.
Recommended workflow
- Choose a copy of the source image.
- Set the maximum width and output format.
- Preview file size and dimensions.
- Download the compressed result and keep the original separately.
When not to use it
- Do not discard originals when image quality matters.
- Do not use browser compression for legal evidence or archival images.
- Do not assume metadata will be preserved.

FAQ
Are images uploaded?
The current Toolkits image workflow processes images in the browser and does not intentionally upload them.
Which format should I choose?
Use JPEG for photos, PNG for sharp transparent graphics, and WebP for many web publishing cases when compatibility is acceptable.
