Postimages (postimg.cc) is a free, anonymous-friendly image host popular for forum posts. It works, but there's no API, no on-the-fly resize, no animated-WebP conversion, and no custom domain. swiftimg keeps the zero-friction anonymous upload and adds a clean REST API, transforms, signed URLs, and white-label delivery.

swiftimg vs Postimages — FAQ
Will my old postimg.cc links keep working?
Yes — Postimages hosts your existing uploads. You can keep them there and use swiftimg for new uploads, or re-upload to consolidate.
Is swiftimg as anonymous-friendly?
Yes. Anonymous uploads work without an account, return a delete token, and don't expire — same model as Postimages, with API + transforms on top.
Why pay for an alternative if Postimages is free?
If you need an API, on-the-fly transforms, or a custom domain to embed images under your brand, Postimages doesn't have those — swiftimg's free tier still does anonymous web upload for the same use case.
