Iterative local compression
Total Privacy — We Don't Save It Anywhere (0 Uploads Policy)
Your photo is never uploaded in the first place. The entire resizing process happens locally, inside your own browser, on your own device. There's no upload step to intercept, no server log to worry about, no brief window where your file exists somewhere outside your control. We don't delete your file afterward because we never received it to begin with. If you want to verify this yourself, turn off your WiFi right after this page finishes loading — the tool will still work perfectly, because it never needed an internet connection.

How to Resize Image Dimensions & File Sizes
Resize a photo to exact pixel dimensions, a target file size, or both — useful for exam forms, ID uploads, or simply making a photo smaller for the web. Lock the aspect ratio to avoid stretching, or set custom dimensions manually. Processing happens entirely on your device.
Frequently Asked Questions
What's the difference between resizing and compressing?
Resizing changes an image's pixel dimensions (width and height); compressing reduces file size (KB/MB), often by adjusting quality. Many forms require both — the right dimensions AND a file size limit — which this tool handles together.
Can I resize without changing the aspect ratio?
Yes — lock the aspect ratio toggle keeps your photo from looking stretched or squeezed.
Can I resize a signature the same way?
Yes — for exam-specific signature presets, see our dedicated Signature Resizer.
