Crop and compress images to standard blog sizes — featured banners, in-article images, and author avatars — in one browser pass.

- Enable WebP export and optional watermark removal if needed.
- Download optimized assets ready to drop into your CMS.
Output Sizes
Example
A WordPress blogger uploads a 4000×3000 px photo. The prepper exports a 1200×675 featured banner and 800×450 inline image as WebP files under 100 KB each — ready to drop into the CMS without manual cropping.
Frequently Asked Questions
What output sizes does it create?
Common outputs include 1200×675 px featured banners, 800×450 px in-article images, and 150×150 px author avatars aligned with modern responsive blog layouts.
Why are files converted to WebP by default?
WebP delivers smaller file sizes than JPEG or PNG at similar visual quality, which helps pages load faster and improves search performance.
How does Gemini watermark removal work?
When enabled, the tool trims a clean 12% strip from the right edge of the image, removing common AI-generated logo watermarks without affecting the main subject.
Will cropping cut off important parts of my image?
The engine fits your image to the target dimensions while preserving borders and legibility. It avoids aggressive center-cropping that often removes text or key details.
Are my images uploaded to a server?
No. All cropping, resizing, and compression happen locally in your browser. Your files are never sent to external servers.
Can I prep multiple blog images at once?
Yes. Upload several images and process them through the same size and quality pipeline, then download each optimized asset.
How does this help with SEO and page speed?
Correctly sized, lightweight images load faster, reduce layout shift, and support better Core Web Vitals — all signals that search engines reward.
