About Image Optimizer

Image Compression

The app minimizes your image weight while maintaining the image quality.

  • Compression type - Lossless: reduce image size by 15%, preserve image quality by 100%.
  • Compression type - Lossy: reduce more image size by 30%. You can define your own settings, thus minimize the image weight even more. With proper optimization of images, the app can save a huge website weight, thus naturally make the site load much faster.

Compress All Image Types and Even Other Images (Custom Upload Feature)

  • The app can compress product images, collection images, blog post images, asset images. The compression action can be done manually or in bulk. You can select separate products or collections and check the preview before hitting the Start button.
  • Custom Upload feature: you can manually upload and compress any image.

Automatically Updating ALT Text To Improve SEO Ranking

The search engine can not “read” your product images like scanning text on your website, thus you need image ALT text to make sure Google crawler bot understand what your image is about and able to rank it accordingly. Images with optimized and keyword-rich ALT text can help to improve SEO and get better ranking in Google Image Search.

  • Automatically optimize the ALT text of images in bulk.
  • Provide pre-made templates for Product ALT text. Or you can set your own custom ALT text template. [NEW UPDATE]: You can now choose not to overwrite the old ALT text of products. The ones you already set ALT text will remain the same.

Convert Image Format From PNG To JPG

JPG provides the best image quality with the smallest file size, while PNG tends to be in a much bigger size. Converting image format from PNG to JPG can save you a lot in image weight.

Automation for Image Compression and Image ALT Update

The app will scan for new images (once per week) and automatically optimize them according to your pre-set setting. Even when you log out of the app or Shopify, the automation is still on-going.

Display Text-Based Watermarks On Images

The app includes a watermark on your images to protect images from thieves. With the text-based watermark, you can customize it any way you wanted.

Image Backup and Restore

We always store your original images in at least 30 days so that you can back them up in any case. Just 1 button and you can restore individual images or all images.

Fairly priced and does what it says on the tin :) Glad I found this compared to a bunch of the others on offer for ludicrous pricing!


Pathetic app. Actually made my site speed slow as compared to before. Pathetic customer support. Have asked for refund.

Quality app with fast image compression. Some other apps seem to be a little slow but Image Optimizer completes the task in good time.
