Image Cropping Guide

Crop Image by Pixels — Exact Width, Height & Coordinates

Crop by pixels with custom dimensions. Crop image to exact size and crop image width and height on Canvas — precise image cropper for portals and ad slots.

Set width×height and map X/Y on Canvas for exact pixels (1080×1080, 1920×1080, 1200×628, and more). Convert HEIC first; JPG/PNG/WebP crop natively.

X/Y coordinate mapping for pixel-perfect frames

When a form or ad unit lists numbers, ratio presets are not enough. Use this page to crop by pixels, crop image by pixels, and crop image to exact size with custom crop dimensions. Dial crop image by dimensions and crop image width and height until you crop image to exact dimensions that match the brief. Photographers also crop photo by pixels when a marketplace rejects soft auto-crops. Think in Canvas coordinates: origin at top-left, X increases right, Y increases down — map selection left/top/width/height so you crop image accurately every time. Named targets include Crop Image to 1080×1080, Crop Image to 1920×1080, and Crop Image to 1200×628. Pair with resize and crop image when you must both reframe and change output scale. Works as a precise image cropper on crop image windows, crop image mac, and crop image linux browsers. Native JPG/PNG/WebP; convert HEIC to JPG first for iPhone shots.

How it works

  1. 1

    Enter custom dimensions

    Set crop image width and height or pick Crop Image to 1080×1080, Crop Image to 1920×1080, or Crop Image to 1200×628 — custom crop dimensions on Canvas.

  2. 2

    Map X/Y on the selection

    Nudge the box with top-left X/Y logic so crop by pixels and crop image by dimensions land on the subject — crop image accurately, not by guesswork.

  3. 3

    Export exact pixels

    Download after you crop image to exact dimensions. Use resize and crop image with Image Resizer when scale still needs a second pass.

Problems we solve

Portals reject wrong pixel sizes

Crop image to exact size and crop photo by pixels until width×height matches the upload checklist.

Off-by-a-few-pixels framing

Use X/Y mapping to crop image by pixels accurately instead of freehand drifting.

Confusing resize vs crop

Crop keeps a region; resize changes scale — combine resize and crop image when both are required.
