Free Image Resizer FAQ
Everything you need to know about our free AI image resizer.
Is this AI image resizer really free?
Yes, completely. No hidden fees, watermarks, or account requirements. Our AI-powered resizer is free to use with no limits on the number of images you resize.
What image formats can I resize?
You can resize images in PNG, JPG/JPEG, WebP, AVIF, HEIC, GIF, BMP, and TIFF formats. The output format matches your input file, so a PNG stays a PNG after resizing.
What does "maintain aspect ratio" do?
When enabled, the resizer keeps the proportional relationship between width and height. If you set only a width, the height is calculated automatically (and vice versa). This prevents your images from looking stretched or squished.
Is there a file size limit?
Each image can be up to 10 MB. You can upload up to 10 images at once for batch resizing.
Are my images stored on your servers?
Uploaded and processed images are temporarily stored for 4 minutes so you can download them. After that, they are permanently deleted. We do not keep copies or use your images for any other purpose.
What is the maximum output resolution?
You can resize images up to 10,000 x 10,000 pixels. For most social media and web use cases, you will not need anything close to that limit.
Can I resize images for social media?
Yes! Use our quick presets to instantly resize images for Instagram, Facebook, Twitter, YouTube, LinkedIn, Pinterest, and more. Each preset uses the exact dimensions recommended by each platform.
