FAQ
Compress image questions
Is compression lossless?
JPEG and WEBP compression is lossy by design. PNG re-encoding may reduce size but is not the same as vector optimization.
Is document or URL content sent to analytics?
No. Optional analytics records only which tool you used and job status. Filenames, file bytes, page text, and screenshot URLs are never tracked.
Can I automate this for my product?
Yes. See the developer quickstart for API keys, webhooks, and higher throughput when you need automation.
