How to use this image resizer

Use this tool when an image needs a specific pixel size, aspect ratio, or export format before it can be uploaded or published.

  1. Drag an image onto the upload area or choose an image file.
  2. Enter the output width and height you want, or choose a preset size.
  3. Position and resize the crop box directly on the image.
  4. Download in the uploaded file type, or choose another format from the arrow menu.

Supported image types

The resizer accepts JPG, PNG, and WebP images from a local file. Downloads use the uploaded file type by default, with other formats available from the download menu.

Use JPG for photographs when broad compatibility and smaller file sizes matter. Use PNG when sharp edges, screenshots, or transparency are important. Use WebP when you want modern compression and the destination supports it.

Resizing changes pixel dimensions. Cropping changes the composition by selecting part of the image. If a platform requires a fixed ratio, such as a square post or widescreen thumbnail, crop deliberately so important faces, text, logos, or product details are not cut off.

How resizing works

The selected image is decoded locally, edited with a browser crop box, drawn to a canvas at the requested dimensions, and exported as a downloadable PNG, JPEG, or WebP file. The original image is not uploaded or stored by utilkit.

The crop box preserves the requested output ratio so the downloaded file is not stretched. If the requested size is larger than the source crop, the browser has to upscale pixels, which may make the result look softer. For best quality, start with an image that is at least as large as the final size.

Metadata such as camera EXIF data may not be preserved in the exported canvas image. That is usually helpful for privacy and file size, but it matters if you need to keep original camera details.

Image resizer FAQ

Are my images uploaded?
No. The image is read and resized in your browser.
What file type will I download?
The main download button uses the uploaded file type. Use the arrow menu to choose another format. JPEG downloads fill transparent areas with white.
Will resizing make a small image sharper?
No. Upscaling can create a larger file, but it cannot restore detail that was not in the original image.
What size should I choose for social media?
Use the preset closest to the platform and placement you need, then check the platform's current image requirements before publishing important assets.
