Local first
Compression, conversion, editing and privacy cleanup run in the browser whenever practical.
About Image Toolkit
Image Toolkit provides browser-based image tools with clearly labeled local and cloud processing.
AI with labels
On-device, cloud and preview features use different badges and disclosures.
Workflow oriented
A useful result should lead naturally into the next tool without another upload.
Technical architecture
Astro renders the product and content layer. React islands power interactive workspaces. Cloudflare Workers handles authenticated routes, D1 stores account and usage records, and R2 holds explicitly uploaded temporary sources. Local files do not touch those services.
