About iDuckImg
24 free image tools that run in your browser, from the makers of iDuckPDF.
What happens to your files
Every tool runs in your browser. Your pictures are opened, changed and saved on your own device, and they are not uploaded to our servers. Our host, Cloudflare, sees the same ordinary web requests for our pages that any website sees. Please do not rely on that alone for anything truly secret: check any tool you trust, and close the tab when you are done.
Who runs it
iDuckImg is made and run by Basic App Company. It is a sister site ofiDuckPDF, which has free PDF tools, and shares its look.
What it costs
Nothing. There is no sign-up and no watermark on your results. We may show ads to cover the running costs, and we will keep them away from the upload area and the download button. See Support for ways to help.
How it is built
The pages are plain static files made with Astro, with small Preact pieces for the tools. The heavy lifting is done by open-source code compiled to WebAssembly and run in a background worker in your browser: jSquash for JPG, PNG and WebP, libheif for iPhone HEIC photos, and pdf-lib for PDFs. Because everything runs on your device, large photos can take a moment on an older phone.
