Upload an image and resize it to exact dimensions or a percentage — right in your browser.
About the Image Resizer
Our free image resizer changes your photos to any exact width and height — by pixels or by percentage — without uploading anything. Bloggers use it to fit featured images, favicons and thumbnails; sellers use it for marketplace photo requirements.
How to Use the Image Resizer
- Choose an image file.
- Enter a width and height, or set a scale percentage (e.g. 50% for half size).
- Keep Lock aspect ratio on to avoid stretched images.
- Pick PNG, JPEG or WebP output and click Resize & Download.
Tips
- Blog featured images: resize to your theme's recommended size (often 1200 × 630) for faster loading.
- Thumbnails: use percentage scaling to keep proportions.
- Format choice: WebP gives the smallest files; PNG keeps transparency.
Frequently Asked Questions
Will resizing reduce quality?
Downscaling is safe; upscaling beyond the original size can look soft. For best results, resize down, not up.
What is aspect ratio lock?
It keeps width and height proportional so circles stay circular — turn it off only when you intentionally want to crop-stretch.
Is my photo uploaded?
No — resizing happens locally in your browser; your images never leave your device.
