Years in this space

I've evaluated a lot of these over the years. What stands out here is works in any modern browser — handled better than most — and supports common image formats. Output quality varies by source image is my one real gripe. Worth the time if this is your use case.

Solid for our team

We rolled this out across the team last quarter and simple, no-install browser workflow. Drag-and-drop upload fits neatly into how we already work, and downloadable processed files removed a step we used to do by hand. Output quality varies by source image, which is the main caveat, but it has held up under daily use.

Does the job

Pretty happy overall. Drag-and-drop upload just works and supports common image formats. but no dealbreakers — I'd recommend it to a friend without hesitating.
