About the X Post Image Resizer

The output is exactly 1600 x 900, which is the size X expects.

Filling the frame keeps proportions and crops the edges; fitting keeps the whole image and pads around it. Neither ever stretches the picture.

Platforms re-compress uploads regardless, so exporting at the exact size gives their encoder the least work to do and produces the sharpest result.

Questions people ask

Is your image uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your image never leaves your device. You can confirm it by opening your browser's network panel while the tool runs, or by disconnecting from the internet after the page has loaded.

Is it free, and do I need an account?

Yes, it is free, and there is no account, no sign-up and no watermark on the result. The project is funded by optional donations.
