Image Resizer
Change an image’s width and height, with common size presets. The work happens in your browser — the file or text is not uploaded to ToolVerse.
Or drop a JPG, PNG, WebP or GIF here. Maximum 15 MB. Processing stays on your device.
How to use this tool
- Choose or drop an image (JPG, PNG, WebP or GIF, up to 15 MB).
- Enter a width and height, or pick a preset. Keep the aspect ratio on if you do not want the image stretched.
- Choose a download format and save the file. Check the result before you publish it.

Frequently asked questions
Is my image uploaded?
No. Resizing uses the canvas in your browser. The image is not sent to a ToolVerse server.
Will the image look stretched?
If “Keep original aspect ratio” is on, changing one side updates the other. Turn it off only if you want exact width and height, which can stretch the picture.
What happens to animated GIFs?
The browser reads a GIF as a still image, usually the first frame. Animation is not preserved.
Is there a size limit?
The tool accepts files up to 15 MB, and each side can be up to 10,000 pixels. Very large images may be slow or may fail on phones with limited memory.
