Frequently Asked Questions
Quick answers about free downloads, augmentation, splits, and licensing.
Getting started
Search: Find a dataset by keyword (e.g. "traffic lights", "cats") on the search page.
Configure: Pick image size, color mode, and your train/val/test split on the download page.
Augment (optional): Choose augmentations and set the percentage of train images to augment.
Download: Hit download — get a ZIP with an ImageFolder-style layout and a meta.json README.
Train: Plug the folder straight into PyTorch / TensorFlow / Keras. No preprocessing required.
What is images.cv?
images.cv is a free catalog of labeled image datasets for computer vision. Browse, search, and download datasets for classification, detection, and segmentation — no signup required.
Who is it for?
Researchers, students, ML engineers, and product teams that need ready-to-train data for POCs, course work, fine-tuning, or baseline models.
Do I need an account to download?
No. Every dataset on images.cv is free to download anonymously. If you want downloads to arrive by email or save your search history, you can create a free account.
How many images are available?
Millions across thousands of categories. Use the search page to filter by keyword, class, and minimum image count.
Which exports and options are available?
Choose output image size, color mode (RGB / grayscale), and train/val/test split before you download. Datasets arrive as a ZIP with an ImageFolder-style layout ready for PyTorch, TensorFlow, or Keras.
Can I augment images at download time?
Yes. Pick augmentations (rotate, flip, crop, blur, noise, color jitter, and more) and choose what percentage of the train split should be randomly augmented. A slider lets you set the ratio from 0% to 100%.
Where do the images come from?
Images are aggregated from public web sources and community contributions. Datasets are intended for research and educational use; always verify the underlying license for your specific use case.
How large are the downloads?
The download page shows a live size estimate based on your image size, color mode, and augmentation settings. Small datasets are a few MB; the largest reach several GB.
Can you build a custom dataset for my team?
Yes — our B2B team delivers production-grade labeled datasets with QA, custom classes, and annotation formats (YOLO, COCO, segmentation masks). See For Business for scope and timeline.
How is images.cv funded?
images.cv is a free resource supported by voluntary donations (Buy Me a Coffee) and our B2B custom-dataset service. There are no paid consumer tiers for the public catalog.
Found a bad image or broken label?
Open any dataset and use the report button on the image thumbnail — our team reviews reports and removes problematic samples.
