What this tool does
Use Image Optimizer when a file looks fine but is still too heavy for the next step in the workflow. That usually means screenshots for documentation, product images for a CMS, assets for a changelog, or visuals attached to tickets and internal notes. The goal is simple: reduce weight without introducing unnecessary friction or sending the file to a third-party compression service.
- Compresses and resizes images directly in the browser before publication or sharing.
- Helps you compare common output formats such as PNG, JPEG, and WebP depending on the kind of asset.
- Makes it easier to reduce file size before uploading screenshots, blog assets, release images, or support material.
How to use it
- 1
Upload the image you want to optimize.
- 2
Choose the output size, format, or compression level based on where the file will be used.
- 3
Preview the result and compare file size against visual quality.
- 4
Download the optimized image and use it in your docs, CMS, ticket, or website.
Example
A developer exports a 3 MB PNG screenshot for a changelog entry, converts it to a smaller WebP, and keeps the text readable while cutting the upload size.
Use cases
- Compressing screenshots before adding them to documentation, support tickets, or release notes.
- Preparing lighter assets for a CMS, blog post, changelog, or landing page.
- Reducing file size before sharing images in issues, internal docs, or product handoff.
Common mistakes
Over-compressing images with text
Screenshots, UI captures, and diagrams often need gentler settings than photos. If the image contains labels or code, check readability before exporting.
Picking the wrong output format
JPEG is fine for photos, but PNG or WebP may preserve sharp UI edges better depending on the source image.
Only checking file size
A smaller file is not automatically a better result. Always review dimensions and clarity in the context where the image will be used.
FAQ
When should I use PNG, JPEG, or WebP?
PNG is often better for UI captures, diagrams, and transparency. JPEG is usually better for photos. WebP is a good choice when you want smaller files for the web and the target environment supports it.
Will compression make my screenshots blurry?
It can if you push the settings too far. Images with text or code should be checked carefully after compression.
Is this useful for documentation work?
Yes. Large screenshots slow down docs, make uploads heavier, and create friction in review workflows.
Should I resize before compressing?
Usually yes. If the source image is much larger than the final display size, resizing often delivers the biggest reduction.
Can I use it for internal or unpublished assets?
It is designed to keep processing in the browser, which reduces unnecessary exposure, but you should still follow your own handling rules for sensitive material.
Privacy and security
- Image processing is designed to stay in the browser.
- Files are not sent to a remote optimization service by default.
- That reduces unnecessary exposure when you are working with draft assets, internal screenshots, or unpublished material.

Next step
Use Image Optimizer when the image is ready visually but still too heavy for the workflow around it. Compress it, resize it, and move on with a lighter file that is easier to publish and share.
