Bulk Upload Optimized Images to Blogger

Uploading multiple images to Blogger can be time-consuming, especially if they aren't optimized. Slow-loading posts not only frustrate readers but also affect your SEO and Google Discover reach. Fortunately, by using image compression tools and smart upload strategies, you can boost performance and save time.

In this guide, you’ll learn the best ways to compress, prepare, and bulk upload images into Blogger — the right way for SEO.

Bulk uploading is ideal for long-form posts, tutorials, product reviews, and portfolios. But it's essential to ensure your images are fully optimized to avoid slowing down your website. Luckily, you don’t need to sacrifice quality to reduce size.

Why Optimized Images Matter

Uncompressed images can slow your pages, especially on mobile. Optimized visuals help pass Google's Core Web Vitals — a key SEO factor. Tools like ProCompressor make it easy to batch-compress images and download them in a ZIP file, ready for upload.

Step-by-Step: Uploading Images in Bulk

Follow this workflow to upload SEO-friendly images into Blogger quickly:

1. Compress your images using ProCompressor.
2. Use descriptive filenames with relevant keywords (e.g., seo-image-upload.jpg).
3. Go to Blogger post editor → click the image icon → select multiple images.
4. Upload all images at once from your ZIP folder (after extracting).
5. Use the "center" alignment and "original size" for display quality.
6. Add alt text to each image using your keyword: e.g., “upload images Blogger SEO.”

Extra Tip: Use the Right Image Dimensions

For best results on Google Discover and featured snippets, use 1200x675 px for featured images. This 16:9 ratio ensures your images scale perfectly across devices.
