Guides & learning hub
Practical, no-fluff guides for preparing product images the right way — alt text that helps shoppers and search engines, clean filenames, and naming conventions that scale. Every guide pairs with the free AltForge tool, which does the work in your browser with nothing uploaded.
Alt text for Etsy & product images
Accessibility-first alt text, the 125-character guideline, what to include and leave out, with real examples.
Bulk rename product photos
Why filenames matter for Shopify & Etsy, naming conventions that scale, and a safe manifest-based workflow.
SKU & filename naming conventions
Deterministic slugs, hyphen separators, field order, length limits, and de-duplication for a tidy catalog.
Alt-text checklist
A people-first pre-publish checklist: what to include, what to omit, length and tone, common mistakes.
Preparing a rename manifest
Build and apply a bulk product-image rename manifest safely, from slug rules to avoiding duplicates.

Frequently asked questions
Is AltForge really free?
Yes. The core tool is free with no account and no sign-up, and you can process unlimited images per batch. A Pro tier is planned but not live yet — nothing is for sale today.
Are my images or CSV uploaded anywhere?
No. Everything is read and processed locally in your browser. No image or spreadsheet is ever uploaded, and there are no analytics or tracking scripts.
How long should alt text be?
Aim for a concise phrase under about 125 characters — usually 8 to 16 words. Lead with the product type, add the key attribute, and skip "image of".
Why rename product image files?
Descriptive names are easier to manage, avoid upload collisions, map images to SKUs, and give search engines a small extra signal. Camera names like IMG_4821.jpg say nothing.
Do I need an account or install anything?
No account, no installation. AltForge runs entirely in a modern web browser and works on your machine once loaded.
Does it work for Etsy and Shopify?
AltForge is a standalone, brand-neutral tool, not affiliated with any marketplace. Its editable drafts and clean slugs are useful wherever you manage product images. You review the final output.
