Why resize images on-device?

Profile photos, product shots, and screenshots often need exact dimensions before upload. Sending originals to a random “free resizer” risks exposing faces, documents in the frame, or EXIF GPS. This tool uses the HTML5 Canvas API to scale pixels in memory. Set width/height or a percentage, keep aspect ratio, and download. On-device security means the source file never leaves this browser tab.

How to resize an image

  1. Drop a JPG, PNG, or WebP (or click to browse).
  2. Enter target width/height in pixels, or a percentage scale.
  3. Keep aspect ratio locked unless you intentionally want a stretch.
  4. Download the resized image — processing never left your device.

Frequently asked questions

Is upscaling the same as AI enhance?
No. This resizer uses standard canvas interpolation. For enlargements, expect some softness. For true AI upscale, use the dedicated image upscaler tool if available.
Are my photos uploaded?
No. The File API loads the image into memory; canvas draws the scaled result. No image bytes are sent to a Just Tool It backend.
Which formats are supported?
Common web formats the browser can decode — typically JPEG, PNG, and WebP. Output format follows what the tool exposes in the UI.
Can I resize for Instagram or avatar sizes?
Yes. Enter the exact pixel size required by the platform (for example 1080×1080 or 400×400) and download.
