Image Resizer

Good times to use it

Use Image Resizer for preparing images for thumbnails, hero sections, product cards, social previews, and fixed upload requirements. It works well when you want a resized image in the chosen format and do not need a bigger workflow around it.

• Best fit: preparing images for thumbnails, hero sections, product cards, social previews, and fixed upload requirements.
• You start with an image plus target width, height, or scale.
• The useful choices are target dimensions, aspect ratio lock, scale percentage, format, and quality.
• Check distortion, blurry details, text readability, file size, and whether the crop should happen before resizing.
• You end up with a resized image in the chosen format.

Use Image Resizer like this

1. Start with an image plus target width, height, or scale.
2. Choose target dimensions, aspect ratio lock, scale percentage, format, and quality.
3. Run the tool once, then review distortion, blurry details, text readability, file size, and whether the crop should happen before resizing.
4. Copy, export, or download a resized image in the chosen format.
5. Open the export at the size people will actually see before you publish it.

Easy ways to ruin the result

• Upscaling cannot add real detail; it only creates a larger version of the available pixels.
• Keeping aspect ratio prevents distortion when only one dimension needs to change.
• Crop first when composition matters, then resize to final dimensions.
• Use exact dimensions when a marketplace or CMS rejects oversized uploads.

What changes the output

• The selected image is drawn to a canvas at the requested dimensions.
• Contain, cover, and stretch modes control how the source fits the output.
• Transparent images converted to JPG use a white background.
