The form says 200 KB. Your photo says 4.2 MB.

Drop it on any tool below and it comes back the right size, in the right shape. Everything runs in this browser tab — the file is never uploaded to a server.

Why nothing gets uploaded

Most sites that promise to resize an image quietly send it to a server, resize it, and send it back. That is a round trip of several megabytes, a copy of your photo on someone else's disk, and a wait.

These tools use the canvas element and a bit of arithmetic to do the same job inside the tab you already have open. There is no upload endpoint, and no server-side code that could store a file even if it wanted to. Turn off your Wi-Fi after the page loads and every tool here keeps working.

The trade-off is that very large files (over about 60 MB) can exhaust a phone's memory and crash the tab. For those, use a desktop machine.

Questions

Is there a file size limit?

Practically, around 60 MB on a desktop and less on older phones — the limit is your device's memory, not a server rule. The tools warn you before trying.

Do you keep my images?

There is nowhere for them to go. The processing happens in JavaScript in your browser; no image data is ever sent over the network.

Why does it say HEIC is not supported?

HEIC is Apple's format, and only Safari can decode it. If you are on a Mac or iPhone, your photo is already readable. If you are on Windows or Chrome, export the photo as JPG from the Photos app first.

Can I use these commercially?

Yes. The output files are yours, with no watermark and no attribution requirement.
