How it works
- Drop your images.
- Choose a longest side, or exact width and height.
- Resize and download individually or as a ZIP.
Why nothing is uploaded
Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.
Verify it yourself
- Open your browser’s developer tools (F12) and select the Network tab.
- Load your file and run the tool.
- The only requests you will see are the tool’s own code and, once cached, none at all.
Frequently asked questions
Why do resized images here look less jagged?
Because large reductions are done in halving steps rather than one jump. Drawing a 6000-pixel photo straight into a 400-pixel box makes the browser sample too few pixels and the result crawls with aliasing; halving repeatedly averages properly.
Can I enlarge an image?
You can, but nothing is gained: the detail is not there to recover. Upscaling is only worth doing when a system demands a minimum pixel count.
Are the images uploaded to convert them?
No. The image is decoded by your browser, redrawn on a canvas and re-encoded there. Load the page, switch your connection off and the conversion still works — that is the proof.
Is there a size or batch limit?
None that we impose. Drop a hundred files if you like; they are processed one after another with a progress bar, and the ceiling is your device’s memory.
What happens to EXIF and GPS data?
It is dropped by default, which is usually what you want before sending a photo to anyone. Tick “Keep EXIF” if you need the capture date and camera preserved in a JPEG output.
