Product facts

BatchMint is a static browser application that processes up to 20 JPEG, PNG or static WebP inputs locally and exports JPEG, PNG, WebP or AVIF. This page separates implemented behavior from future plans and marketing assumptions.

What the current build is

BatchMint is a static Astro website with a React image workspace. The deployed product is a browser application rather than a hosted image-processing API: transforms run behind the local processing engine in Web Workers, and completed files return to the page as browser Blobs for review and export. Planned cloud processing is not presented as a current capability.

Current inputs, outputs and batch limit

Fixed processing order

Worker and device behavior

Heavy decoding, resizing, watermarking and encoding run outside the main interface thread in local workers. Desktop processing uses no more than four workers, while mobile uses one to reduce decoded-image memory pressure. A cancelled job stops queued work and completed object URLs are released when the interface no longer needs them. Device speed, memory and browser implementation still affect the experience.

Privacy and network facts

The privacy claim is deliberately narrow and testable.
Data or requestCurrent behavior
Selected image bytes and decoded pixelsRemain in the page and local workers
Original filenames and watermark textNot included in BatchMint application network requests
Presets and brand kitsStored in the current browser profile through IndexedDB
Website assetsHTML, JavaScript, CSS, fonts, service worker and codec assets are downloaded normally
AdvertisingPublic content pages may load approved advertising; the workspace excludes the AdSense site script

Export and local persistence

Finished files can be downloaded individually, written to a user-approved folder where the browser supports File System Access, or collected into ZIP volumes. The CSV report records processing outcomes without sending the batch to BatchMint. Presets and brand kits stay in the current browser profile and are removed when that site storage is cleared; BatchMint does not synchronize them across devices.

FAQ

Does BatchMint currently process images in the cloud?

No. The deployed workspace uses the local processing engine. A future cloud engine is an architectural extension, not a current product capability.

How many images can one batch contain?

The current limit is 20 JPEG, PNG or static WebP inputs per batch.

Are product defaults marketplace requirements?

No. Presets and starting values are workflow conveniences. Current Shopify, Etsy, Amazon or other platform rules must be checked separately before upload.
