Your image stays in your browser. The file is decoded with browser APIs and processed with canvas without a ClearUtils server upload.
Prepare web-friendly assets
Resize, compress, or convert images before adding them to websites, documents, support tickets, social posts, or product pages.

What this tool does
Resize browser-local images by width and height with aspect-ratio locking, file-size display, preview, and download output.
Common use cases
Resize an image locally before uploading it somewhere else, sharing it, or preparing a web-friendly asset.
Use Image Resizer when you need to prepare an image for a website, upload form, document, support ticket, or shareable asset while keeping the file in your browser and moving only to related image conversion or optimization tools when needed.
How to use it
- Choose or drag a supported image file into the upload area.
- Review the preview, file type, file size, dimensions, and available options.
- Process the image in your browser, then download the output file.
Example workflow
Choose the image file in your browser, review the preview and output settings, run the image operation, then download the result. If the asset still needs work, continue with related image tools such as crop, resize, compress, convert, or metadata cleanup.
Privacy note
Image resizing runs locally in your browser. Your image stays in your browser and is not uploaded or stored by ClearUtils.
Practical notes for this tool
Best use case
Use Image Resizer when a website, profile, CMS, marketplace, email, or documentation workflow needs a predictable width and height before compression, conversion, upload, or handoff to another image tool.
Prepare a blog hero image
Source image: 4000 × 2600 JPG from a camera export
Resized 1600 × 1040 image with aspect ratio preserved, ready to compress or convert for publishing
Privacy and local processing
Image resizing uses browser file APIs and canvas processing. The selected file is processed in your browser and is not uploaded, stored, or sent to a ClearUtils server.
Limitations to know
- Resizing cannot recover detail that is not present in the original image.
- Very large images can still be limited by browser memory or device speed.
- Canvas export may change metadata and compression characteristics.
Practical FAQ
Should I resize before compressing an image?
Usually yes. Reducing pixel dimensions first removes unnecessary data, then compression can focus on the final display size instead of preserving pixels you will not use.

Does the image resizer upload my file?
No. Your image stays in your browser and is processed with browser APIs and canvas.
What file types are supported?
The first version supports JPG, JPEG, and PNG files up to 10 MB and 25 megapixels.
Can I keep the original aspect ratio?
Yes. Keep aspect ratio is enabled by default so changing width automatically calculates the matching height.
