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:
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)

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.
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.
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.

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.

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

Compress using LOSSY https://compressor.io Note: using LOSSY compression reduces storage size of image significantly but loses a minor amount of quality.
