Frequently asked questions
Which image formats can I work with?
JPEG, PNG, GIF, WebP, TIFF, and AVIF are popular starting points. Available input and output formats vary by Robot, so you can choose the right workflow for photos, graphics, or animated images. Browse supported image formats.
Can I create several image sizes from one upload?
Yes. Add several resize steps to one Template and reuse the same input. You can make thumbnails, product cards, and larger images in one API call. Explore image resize options.
How do I make images smaller without changing their dimensions?
Use image optimization to reduce file size, or choose a different output format and quality setting when resizing. Savings depend on the original image and the settings you choose. Learn about image optimization.
Can I crop images and add watermarks?
Yes. Control crop strategy, dimensions, and positioning, then add a text or image watermark. Save those settings in a Template to keep results consistent across uploads. See the available image controls.
Can I remove EXIF data from public images?
Yes. Enable metadata stripping in your image resize step to remove image metadata from its output. This is useful when originals contain information you do not want to publish. Read about the strip parameter.
Can I keep images in my own storage or transform them on demand?
Yes. Export prepared images to your own storage, or use Smart CDN to transform supported images when requested and cache the results. Choose the approach that fits your publishing workflow. Explore on-demand delivery.
How can I estimate and control costs?
Rates vary by operation and usage. Set a soft bill limit for alerts or a hard limit to stop processing. For larger workloads, ask about volume pricing and extra priority slots. Estimate your workflow costs.
