Common Tool67 image workflows accept standard web image formats such as JPG/JPEG, PNG and WebP. Some upload components can help with HEIC/HEIF conversion, while other tools may ask you to convert the file first.
Why can limits differ?
Different AI providers and local workflows have different input requirements. The uploader on each tool page shows the current number of files, size and dimension limits for that workflow.
If a file fails, try exporting it as a standard RGB JPG or PNG and upload again.
