What does this image resizer do?
An image resizer changes the pixel width and height of a picture. This editor also lets you crop before resizing, so you can remove unwanted edges, improve composition or match a required shape without stretching. It works with JPG, PNG and WebP files directly in your browser.
After adding an image, drag the crop frame or its edge and corner handles. Ratio presets cover Free, Original, 1:1, 4:5, 4:3, 16:9 and a custom W:H ratio. Platform size presets (Instagram, YouTube thumbnail, Open Graph and more) set both the crop shape and the export dimensions in one step.
How to crop and resize an image
- Upload a JPG, PNG or WebP image, or paste one from the clipboard.
- Optionally pick a size preset for common social and web formats.
- Move and resize the crop frame; use Precise crop for exact coordinates.
- Choose Exact pixels, Percent of crop, or Fit within max width/height.
- Keep output ratio locked in Exact mode to avoid distortion.
- Choose JPG, PNG, WebP or keep the source format; set quality, JPG background colour and resampling if needed.
- Create the image, review the preview and download the finished file.
The crop size and output size are separate. For example, you can select a 1200 by 800 pixel portion and export it at 600 by 400 pixels, at 50% of the crop, or fitted inside a 1920×1080 box.
Formats and quality
JPG is often best for photographs and offers quality plus a background colour for transparent areas. PNG keeps sharp graphics and transparency. WebP is efficient for the web. Resampling controls how pixels are interpolated when you scale (High is the default; Off uses nearest-neighbour).
Why edit locally?
Local editing avoids an upload queue and keeps personal images on your device. Your original file is never changed; the tool creates a separate result for download.
