About this tool
The PixelForge Image Resizer lets you resize images to any pixel dimensions, percentage scale, or maximum width/height — directly in your browser with no server upload. Resize images before uploading to WordPress, Shopify, social media, or email to reduce page load times and storage usage. The tool preserves aspect ratio by default, but you can also set exact dimensions for thumbnails, avatars, and other fixed-size requirements.
Frequently Asked Questions
Yes. The 'Lock aspect ratio' option is enabled by default. Enter one dimension and the other is calculated automatically.
Yes. Switch to percentage mode to scale the image by a relative amount — for example, 50% to halve both dimensions.
Resizing to smaller dimensions always reduces file size. The exact reduction depends on the format and content. Combine resizing with the Image Compressor for maximum size reduction.
JPG, PNG, WebP, and GIF are all supported as input and output.
No. All resizing is done locally in your browser using the Canvas API. Your images are never transmitted anywhere.
