Image Resizer

Resize images to exact pixel dimensions

Leave height empty to keep the aspect ratio. Set both for exact dimensions. Original format (PNG/JPG/WebP) is preserved.

About Image Resizer

Design specs and platform requirements often demand exact pixel dimensions, and eyeballing a resize never lands you on the precise numbers. The Image Resizer lets you set the width and height in pixels so your output matches the spec exactly, whether that's a 1200x630 social card or a 64x64 avatar.

Upload an image, enter your target dimensions, and the tool resamples it to those exact pixels and returns the file for download. It works entirely in the browser, free, with no signup and no watermark, so your images stay private. The resized output appears instantly, making it quick to produce assets that fit grid layouts, thumbnails, or any fixed-size slot.

  • Generating fixed-size avatars and thumbnails for a user interface

FAQ

Does it keep the aspect ratio?

Because you set exact width and height, entering mismatched values will stretch the image. Use proportional dimensions if you want to avoid distortion.

Can I enlarge a small image?

Yes, but scaling up beyond the original resolution introduces softness. For genuine quality gains on upscaling, an AI upscaler is the better tool.

What formats can I resize?

It accepts common image formats. Upload your file and it will be resampled to the dimensions you specify.

Can I use Image Resizer on mobile?

Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
