// Why this matters
Most Sanity images are missing portable metadata.
Sanity stores media assets and custom fields, but your image file itself often carries no useful IPTC, copyright, title or description metadata. When the same asset is reused across multiple frontends, portable metadata becomes critical.
43%
Content teams reuse the same Sanity media across websites, apps and campaigns. File-level metadata keeps image context portable everywhere.
2.4x
Cleaner image workflows when metadata is generated before upload and reused across channels.
0
Manual metadata work needed per asset when teams rely only on CMS fields instead of file-level metadata.
// Common image SEO problems
The four gaps that slow down Sanity content teams.
Headless CMS teams often publish the same image to many channels. The same metadata gaps appear again and again, and they are fixable before upload.
02
No copyright protection
Without embedded copyright and creator fields, images reused across multiple frontends lose ownership context and attribution.
03
Disconnected asset context
Generic filenames and empty embedded metadata make it harder for developers, marketers and editors to understand what each asset is for.
04
Manual alt text across channels
When one Sanity asset powers several frontends, teams often rewrite image descriptions manually for websites, apps and campaigns.
Batch metadata for Sanity
Skip the manual work — add brand name, keywords and copyright to all images before upload.
// How Exif Injector helps
One tool. Clean metadata. Ready before upload.
Upload Sanity media assets, describe your brand and content model once, and let AI generate titles, descriptions, keywords and copyright metadata directly inside the files.
EXIF editing
View and edit EXIF fields before assets enter Sanity. Remove GPS, clean device data and keep only the fields your publishing workflow needs.
- Bulk view across files
- Selective field stripping
- GPS removal in one click
IPTC keywords
Relevant keywords written directly into IPTC fields so assets keep context outside the CMS database.
- AI-generated from image + context
- Multi-language support
- Editable before export
AI descriptions & alt text
Generate titles, captions and descriptions that your content team can reuse in Sanity fields, frontend alt text, metadata APIs and SEO workflows.
- One-line title (SEO-ready)
- Full IPTC description
- Accessibility-friendly alt text
Copyright injection
Write creator, copyright, credit line and license terms directly into each asset before it is served through your CDN or frontend.
- Bulk copyright stamping
- License URL embedding
- Creator + credit line fields
Fill IPTC fields in one pass
Use the Sanity template to generate titles, descriptions, keywords and copyright metadata.
// How it works
From media asset to Sanity-ready in three steps.
No plugin required. Use the browser tool for batches or the API for automated Sanity media pipelines.
01
Upload Sanity assets
Drop images exported from Sanity, or connect Exif Injector to your upload pipeline. JPEG, PNG, WebP, TIFF, HEIC and AVIF are supported.
02
Generate metadata
Describe your project, content type, brand, language and target frontend. AI writes keywords, title, description and copyright fields into each file.
03
Download or automate
Download optimized files as a ZIP or send them back to your workflow through API. Upload them to Sanity with metadata already embedded.
We prepared 1,800 headless CMS assets before a Sanity migration. Every image received AI descriptions, IPTC keywords and copyright fields before being pushed to production.

// FAQ
Questions, answered.
Do I need a Sanity plugin to use Exif Injector?+
No. You can use Exif Injector before upload or through API. Your team uploads optimized files back to Sanity Media Library, or automates the workflow in your backend.
Will it work with Sanity-powered websites and apps?+
Yes. The optimized file works with any Sanity-powered frontend, including Next.js, Nuxt, Gatsby, Astro, React Native, mobile apps and custom e-commerce storefronts.
Can I bulk process my existing Sanity media library?+
Yes. Export or download your Sanity media assets, process them in Exif Injector, then re-upload the optimized files. You can also use the API for automated batch workflows.
Does it preserve my image quality?+
Yes. We only write metadata into the file. The pixel data stays untouched. Output format matches input format by default.
Can I automate this for new Sanity uploads?+
Yes. Use the Exif Injector API in your upload middleware, CI pipeline, Make, n8n or Zapier workflow. Each new asset can be tagged before it reaches Sanity.
Is my data safe?+
Images are processed securely, stored briefly during processing, then deleted. Files are not used to train AI models.
Prepare every Sanity image asset in one batch.
Get started. No plugin. Upload your assets and get them back ready for Sanity, your frontend, your CDN and search engines.
