Image batch processing pipeline
A batch pipeline chains several image steps (resize → watermark → round → compress/convert) and runs them over a whole batch in one go, downloading the results as a ZIP. No more repeating the same steps image by image — configure once and process dozens or hundreds the same way. image cat does it all locally in your browser; images are never uploaded.

How to image batch pipeline
- 1Drop multiple images.
- 2Tick the steps you want: limit max width, add a text watermark, round corners, final format and compress-to-target.
- 3Click “Process batch & download ZIP” — each image runs through the pipeline.
- 4Results are zipped and downloaded automatically.
Why use image cat's Image Batch Pipeline?
- Configure once, run the whole batch: uniform resize / watermark / compress across dozens of images, no per-image repetition.
- Local and private: the whole batch stays on your device.
- Lossless intermediates: middle steps use PNG and only the final step encodes to your target format/size, avoiding repeated lossy compression.
Frequently asked questions
No. The entire pipeline runs locally in your browser; images are never uploaded — good for processing large sets of private photos.
In a fixed order: resize → watermark → round → final encode/compress, with each step individually toggleable. This ensures the watermark sits on the resized image and compression happens last for the best quality-to-size tradeoff.
JPG has no alpha channel, so the rounded-away areas fill with black. To keep transparent rounded corners, set the final format to PNG or WebP.
There's no artificial count limit — your device's memory and time are the constraints; more and larger images take longer. For very large images, enable the “limit max width” step first.
