This page processes your file inside this browser tab. It makes no network requests with your data — check it yourself in 10 seconds.
How it works
- Choose an image — its current dimensions load automatically.
- Type a new width or height; the other side follows to keep proportions.
- Pick the output format and quality, resize, and download.
🔒 Your files never leave your device
There is no upload step to worry about, because there is no server. The file you choose is processed by your own browser, on your own device, and the result downloads straight from its memory. Once this page has loaded, the tool keeps working with the internet disconnected — try it in airplane mode. Unlike sites that promise to “delete your files after one hour”, there is nothing to delete: your file was never sent anywhere. See how to verify this yourself →
Frequently asked questions
Is my image uploaded?
No — resizing happens on your device, in this tab.
I need an exact file size in KB, not just pixels.
That's the photo-to-spec tool — it hits pixel dimensions and a KB window together, which is what exam portals demand.
Which format should I export?
JPG for photos, PNG for screenshots and graphics with text, WebP for the smallest files where it's accepted.
Does enlarging an image improve it?
No — upscaling can't add detail. Downscaling is crisp; upscaling is soft.
