Image Resizer
Resize JPG, PNG, and WebP images locally for web, email, and social sharing.
Drop images to resize
Resize JPG, PNG, WebP, or AVIF images locally. Set width, height, or both; Utilumo keeps the aspect ratio and avoids upscaling.
Presets
Browser-only resizing
Images are decoded, resized, previewed, and exported in this tab. Utilumo does not upload your files.
Questions
Will JPG, PNG, and WebP need separate resize tools?
No. The Image Resizer recognizes the format automatically and handles common image formats in one tool.
Does the Image Resizer upscale small images?
No. It fits images inside the dimensions you set and avoids upscaling smaller images.
Can I resize many images at once?
Yes. You can process a local batch and download the results individually or as one ZIP file.
Does Utilumo upload my input?
No. This tool is designed for local browser processing and does not send your input to a server.
Do I need an account?
No. Utilumo tools are built to work without accounts or sign-in.
