Is LeanImg really free, and is there a catch?

Yes, it is free with no paid plan, no credits, and no daily limit. There is no hidden tier that unlocks resolution or removes a watermark, because there is no watermark to remove. The trade-off is that your device does the computing, so very large batches will be limited by your own hardware.

Are my images uploaded anywhere?

No. Every tool runs client-side in your browser using JavaScript and WebAssembly. Your files and the extracted text stay on your machine, which is why the background remover must download its model before the first run.

What are the file limits?

Nine of the eleven tools set a size limit. Batch tools (compressor, resizer, converter, image to text, PDF to text) accept up to ten files of 50 MB each, and the PDF reader stops at page 25. The cropper and favicon generator take one file up to 10 MB, while the upscaler and background remover take one file up to 50 MB.

Can it make compliant passport photos?

It supports passport, visa, and ID photos for 205 documents across 92 countries, auto-detecting the face and applying each document's head-size rules. It also produces a printable sheet for most documents, though some (such as UK online applications) do not require a crop.

How accurate is the AI image detector?

The tool first checks Content Credentials and embedded AI labels, then looks for hidden watermarks, and only then runs a model estimate. In the site's October 2026 test on untouched files it flagged 110 of 114 AI images, while 3 of 69 real photos scored 50% or higher — so treat the result as a signal, not proof.
