How to Crop an Image Precisely

Cropping trims an image down to the part that matters — a clean rectangle, a centred square for an avatar, or a composition-focused cut. This guide shows how to crop precisely (by preset ratio or exact pixels) with the free Crop JPG tool, and when to crop before versus after resizing.

The short version

Open the Crop JPG tool, add up to 30 images, set your options below, press Convert All and download — the whole job runs on your device, so it is free, private and takes seconds.

Step by step

1
Open the tool

Load the Crop JPG page. Nothing installs and nothing signs in — the editor appears immediately, ready for files.

2
Add your images

Drag files onto the drop zone, click to browse, or paste from the clipboard. You can load up to 30 at once for a batch job.

3
Pick the crop

Choose a preset ratio, a shape such as a circle, or enter exact pixel values for x/y/width/height. Crop mode also lets you set a custom region.

4
Convert the batch

Press Convert All. Because everything runs on your device, a whole queue of photos finishes in a few seconds.

5
Download

Save each result individually, or grab the entire batch as a single ZIP. Files keep their original resolution unless you set a cap.

Pro tips & common mistakes

  • Crop first, then resize — cropping to the final ratio avoids stretching.
  • Centred crops suit faces and avatars; offset the box when the subject is not in the middle.
  • Batch it: up to 30 files per run beats doing them one at a time.
  • Keep originals for anything critical — the tool never touches the source file, but always keep your master copy.

Frequently asked questions

Is this really free, with no limits?
Yes. The <a href="/crop-jpg/">Crop JPG</a> tool is unlimited and free — no credits, no sign-up and no watermark on your output. There is no server doing the work, so there is nothing to meter.
Do my images get uploaded anywhere?
No. Everything is computed locally in your browser with Canvas and WebAssembly, so your files never leave your device. That is the whole privacy model of this site.
Will this reduce my image quality?
Operations run at full resolution and re-encode with quality control, so detail is preserved. PNG and WebP outputs keep transparency.
How many files can I process at once?
Up to 30 per batch — load them by dragging, clicking or pasting, run once, and download the results as a single ZIP.
Does it work on iPhone and Android?
Yes — any modern browser works: Chrome, Edge, Firefox and Safari on desktop or mobile, with no installation.
