SEOptim is a batch image SEO workflow for agencies, ecommerce teams, and digital teams with repeated image-optimisation work. Upload an image batch, review localised metadata and accessibility signals, then export WebP images plus CSV metadata โ€” without building a spreadsheet pipeline or publishing AI output blindly.

It began with a real image workload: a friend working independently with local UK businesses needed batch image optimisation, SEO-friendly filenames, and localised alt text. The founder wrote Python scripts to do the work. The scripts helped, but they were inconvenient for the person who needed them. Turning that process into a usable, reviewable workflow became SEOptim.

What you get:

  • Batch image processing
  • WebP-optimised image output
  • SEO-friendly filename candidates
  • Localised alt-text candidates (multiple locales per job)
  • WCAG-aware accessibility scoring with rationale to support human review
  • ZIP, CSV, and PDF exports

Powered by Mistral, with European image processing: hosted in Germany, object storage in the EU, and Bunny.net at the public edge. Outputs stay portable. 14-day trial for up to 50 images (card required)

  • Customization Options
    The app allows users to adjust various parameters such as quality, resizing, and other advanced settings for greater control over the compression.

    Squoosh is an open-source project, meaning that its code is transparent and can be reviewed, modified, and improved by the community.
  • Offline Capability
    The application can also be used offline, adding a layer of convenience for users who may not always have consistent internet access.

Possible disadvantages of Squoosh

  • Limited Advanced Features
    While great for basic compression tasks, Squoosh might lack some advanced features found in professional image editing software.
  • File Size Limits
    There might be limitations on the size of the files that can be uploaded and processed, which could be a constraint for users dealing with very large images.
  • Web-Based Dependency
    As a web application, its performance can be influenced by the browser and device capability, which could vary significantly among users.
  • No Batch Processing
    Squoosh is designed for single-image processing. Users looking to compress multiple images at once will find this feature lacking.
  • Privacy Concerns
    Although it can be used offline, the nature of a web app raises concerns for users who prioritize privacy and data security.
  • Limited Support Resources
    Being a free tool, it doesn't come with professional support, so users might have to rely on community forums or documentation for help.

Questions & Answers

As answered by people managing Squoosh and SEOptim.

What makes your product unique?

SEOptim's answer:

SEOptim combines the whole batch image SEO workflow in one place: WebP optimisation, SEO-friendly filename candidates, localised alt-text candidates, and WCAG-aware accessibility scoring with rationale, then exports everything as ZIP, CSV, and PDF. Compression tools only shrink files; alt-text generators only write text. SEOptim keeps human review in the loop and gives agencies a reviewable, portable output they can hand to clients.

Why should a person choose your product over its competitors?

SEOptim's answer:

If you only need smaller files, a compression tool is faster and cheaper. If you need a delivery network, a CDN is the right choice. SEOptim is for the repeated batch job: upload a client's image batch, review localised metadata and accessibility signals, and export WebP assets plus CSV metadata in one workflow, without building a spreadsheet pipeline or publishing AI output blindly. The European provider stack is documented, and outputs stay portable.

How would you describe the primary audience of your product?

SEOptim's answer:

SEO and digital agencies serving ecommerce or multilingual clients, plus ecommerce SEO and content teams managing large or multilingual image catalogues. Agencies are the primary focus: recurring image batches, short buying paths, client reporting needs, and access to multiple downstream customers.

What's the story behind your product?

SEOptim's answer:

A friend working independently with local UK businesses needed batch image optimisation, SEO-friendly filenames, and localised alt text. The founder wrote Python scripts to do the work. The scripts helped, but they were inconvenient for the person who needed them. Turning that process into a usable, reviewable workflow became SEOptim.

Which are the primary technologies used for building your product?

SEOptim's answer:

Mistral vision-language models generate the metadata candidates. The application is self-hosted in Germany, with EU object storage, and a European CDN at the public edge (Bunny.net). Outputs are WebP images plus ZIP, CSV, and PDF exports.

Who are some of the biggest customers of your product?

SEOptim's answer:

Seoptim is in its launch phase, so no customer names are published yet. The 14-day trial is open for agencies to run a real client batch

  • Can you build a recognizable World Map in under 500 bytes?
    Its a fun challenge. I used https://squoosh.app to make a pretty good one. Mostly just a resize and then OxiPNG for compression. Managed a 124x62 black/white image. OP has a resolution of 195x53, so I had very similar, but slightly worse I think? Mostly a different aspect ratio + map projection I think. Playing with Squoosh.app is very fun, and you can very easily see how the jump from 500b to ~1.5kb turns a map... - Source: Hacker News / about 2 months ago
  • Speed Up Your WordPress Site in 30 Minutes: A No-Plugin Performance Guide
    Use a free tool like Squoosh (by Google) to batch convert your existing images to WebP. - Source: dev.to / 3 months ago
  • Free Browser Tools for Developers Who Make Content
    Every image goes through Squoosh before it lands in any repo I own. Drag the file in, pick WebP or AVIF, drag the quality slider until the preview still looks clean, download. The size reduction is usually 60โ€“80% with no visible quality loss. It runs entirely locally in your browser โ€” nothing is uploaded anywhere. For a performance-conscious developer this matters. Best for: Pre-commit image optimisation, blog... - Source: dev.to / 4 months ago
  • Rust WASM vs TypeScript Performance: Why the 'Faster' Language Lost by 25% [2026]
    The Squoosh image compression app from Google is a great example. It runs codecs like MozJPEG and WebP entirely in WASM, processing large image buffers with minimal boundary crossings. Near-native compression performance, right in the browser. - Source: dev.to / 5 months ago
  • Flutter App Taking Too Long to Start? Here's What You're Doing Wrong
    For images, tools like TinyPNG or Squoosh can reduce file sizes dramatically, often by 60-80%, with little to no visible quality difference. For your splash screen specifically, consider using a simple vector image (SVG) or even a plain color with your logo instead of a heavy raster image. Flutter's native splash screen supports this out of the box and it's blazing fast. - Source: dev.to / 6 months ago
