How batch works
- Select up to 20 images by clicking or dragging.
- Set the maximum file size for all images.
- Each image is processed one at a time, locally in your browser.
- Download individually or as a ZIP archive.
Why one at a time?
Processing images sequentially keeps memory usage low and prevents browser crashes on mobile devices. Each image still gets the full quality search — multiple candidates tested against your size limit.
Questions, answered plainly.
Does my image get uploaded?
No. Decoding, resizing, encoding, and comparison happen in your browser. Images are not sent to our server.
Why does batch take longer?
Each image can take up to 60 seconds. With 20 images, the full batch could take up to 20 minutes. You can cancel at any time and keep results already completed.
Can I add more images after processing?
Yes. After a batch finishes, you can add more images and run another batch. Completed results can be removed individually or cleared all at once.
What if one image fails?
Failed images are marked and skipped. The rest of the batch continues. You can remove failed items and retry or proceed with successful results.
