Usage Guide & Specs
Master bulk resizing for social media, blogs, and e-commerce.
Why Bulk Resizing is Essential for SEO
High-resolution photos from modern smartphones are often 4000px wide and over 5MB. Uploading these directly to a website will destroy your page load speed. Large image files are the #1 cause of failing Google’s Core Web Vitals. Scaling your images down to web-friendly widths (like 1200px or 800px) reduces file size drastically while maintaining visual crispness on digital screens.
Standard vs. Batch Mode
- Single Mode: Ideal for social media. One master graphic can be scaled into specific dimensions for Instagram Posts (1080px), Stories (1080px), and Pinterest (1000px) simultaneously.
- Batch Mode: Built for efficiency. Process a whole folder of product photos for your Shopify or WooCommerce store. Set a target width, and we handle the math for every file.
Privacy: The Client-Side Advantage
Traditional resizers upload your photos to a cloud server. Filebrr uses **Client-Side processing**. When you select an image, your browser generates a temporary local memory object. It draws that data onto an invisible digital canvas, calculates the aspect ratio to prevent stretching, and exports a new file. **Your original data never leaves your computer.**
Frequently Asked Questions
Will it blur my images?
We use high-quality interpolation to ensure that downscaling remains crisp. However, upscaling (making a small image larger) will naturally result in some pixelation as data is being mathematically "guessed."
How many images can I process at once?
Since everything happens in your RAM, there is no hard server limit. Most modern smartphones and PCs can easily handle batches of 50-100 images without lag.
