How to use Crop a PNG Image
- 1. Upload your PNG. Add the image you want to crop, such as graphic.png. Any photo, screenshot or graphic works as long as you know the region you want to keep.
- 2. Set the crop region. Enter Left (px) and Top (px) to mark where the region starts, then set Width (px) and Height (px) to define exactly how large the kept area is, such as 250, 120, 400 by 300.
- 3. Download the cropped PNG. Save the resulting file, containing only the selected region, such as a 400 by 300 area, and use it wherever the cropped subject is all you need.
When to use Crop a PNG Image
Crop a PNG Image cuts out a rectangular region of a PNG and discards the rest. Crop a PNG Image runs entirely in your browser and is for isolating a subject, removing unwanted background, or trimming a screenshot down to exactly the area that matters.
- Isolating a subject from a wider photo. A photographer wants just the center subject of graphic.png and crops the region at 250, 120 with a 400 by 300 size to remove distracting surroundings.
- Trimming a screenshot for documentation. A support engineer taking a screenshot for a help article crops out the browser chrome and irrelevant sidebar to leave only the relevant part of the screen.
- Preparing an image for a specific aspect ratio. A social media manager needs a photo cropped to a square for a profile picture and defines the exact pixel region that keeps the subject centered.
Examples
Crop the center subject
Input
graphic.png + region (250, 120, 400×300)
Output
graphic.png containing only the selected 400×300 region
About the Crop a PNG Image tool
Crop a PNG Image is a free online tool that works entirely inside your web browser. Cut out a rectangular region of a PNG and discard the rest. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 108 PNG utilities on EditSafely. Each one does a single job well, and all of them follow the same rule: your input stays on your machine.
You can shape the output with 4 settings, including Left (px), Top (px), Width (px) and Height (px), and the result refreshes the moment you change one. The finished file is put together in browser memory and saved with the Download button, so it never touches a server on the way to your disk. A worked example further down the page shows exactly what the tool produces for a real input.
Because nothing leaves your device, the tool is suitable for sensitive content such as internal documents, credentials or customer data. It also responds instantly, since every keystroke is handled on your own machine rather than by a remote API.
