About resize image

Resize images to a target box — keep the aspect, crop to fill, or stretch. Batch supported. It sits in the image shelf alongside 168 other image tools, needs no account, and keeps the same behaviour whether you open it here or call it through the REST API.

It takes any image you give it and gives back several files. It runs over a whole batch in one go. The work happens in your browser, so the file is never uploaded and the tool keeps working offline. The same operation is available programmatically at POST /v1/image/resize.

Resize Image questions

Does Resize Image upload my file?

No. Resize Image runs as WebAssembly inside this browser tab: the file is read from your disk by the page, processed on your own machine, and handed straight back. It is never sent anywhere, so there is nothing for us to store or delete.

What files can I use with Resize Image?

Any image file your browser can read. The limit is 100 MB per file.

Can I run Resize Image on several files at once?

Yes — select or drop as many as you need and they are handled together.

Do I need an account to use Resize Image?

No. Resize Image works without signing in, and that is not a trial — it is how the free tier works. An account only matters for things that need one to exist at all: larger server jobs against your quota, API keys, saved workflows and billing.

Can I run Resize Image from my own code?

Yes. Every tool on the site is reachable from the REST API with the same slug — `image-resize` — and the same options as this page, so anything you can do here you can automate against your own files.
