Why this image resizer is useful
Large images can slow down websites, make forms fail, and increase upload time. This page helps you resize photos, crop to common ratios, lower file size and export a cleaner JPG or WebP file.
The tool uses the browser canvas API. For normal use, the selected image is processed locally in your browser instead of being uploaded to Mini-Tools.uk.
Use it when you need a smaller upload, a cleaner crop for a profile or product image, or a quick WebP version for a website. Always keep an original copy if you may need to edit the image again later.
Local processing note
Your image is rendered and exported in the browser. The page does not need an account, API key or remote upload for resizing and compression.
Common use cases
- Compress a photo before uploading it to a website, CMS or form.
- Crop an image to square, landscape or portrait format for social posts.
- Resize a screenshot before attaching it to a ticket or documentation page.
- Convert JPG or PNG to WebP when you need smaller web images.
Is this image compressor private?
Yes. The image is processed locally in your browser and is not uploaded to Mini-Tools.uk.
Can I crop to common aspect ratios?
Yes. You can switch between original, 1:1, 4:3, 16:9 and 9:16 ratios.
Should I use JPG or WebP?
WebP is often smaller at similar quality, while JPG is still a widely compatible option.
