FAQ

Are images uploaded?
Core processing, OCR and model inference run in the browser. Source images stay off the site server.
Does it work on phones?
Yes. Large images and batches use more memory, so keep mobile batches moderate.
How do I compress an image to 200KB?
Open Compress Image to Target Size, enter 200KB and enable automatic resize.
What order should I use for ID or product photos?
