IMAGE CROPPER

Crop images by exact pixels — or drag a dotted crop box

Upload a JPG/PNG, set the crop size in pixels, move the dotted crop area wherever you want, and download the result instantly.

Upload an image to start

Controls

Your image stays in your browser. Nothing is uploaded.
Choosing a preset sets width/height and resizes the crop box. Use Lock to keep the size fixed while moving it.
Tip: Drag the dotted box to choose which area is cropped. Resize handles also work (unless locked).

How this tool works

Set a crop size, frame your image, and export instantly — all in your browser.

This cropper uses a draggable dotted crop box. You can resize it freely, or set an exact pixel width/height (or a preset), then move the crop area to frame the part you want before downloading.

Upload image

Load a JPG/PNG and the crop box appears in the preview.

Set size

Choose a preset or enter exact pixels and click Apply size.

Frame it

Drag the dotted crop box to select the exact area you want.

Download

Export as PNG or JPG. JPG quality applies only when JPG is selected.

Privacy note: cropping happens in your browser. Your image is not uploaded.

Practical guide

When presets help, how Lock works, and how to choose PNG vs JPG.

When to use presets

  • Poster (750×1125) – poster-style artwork crops.
  • Video Thumbnail (1628×1000) – platform thumbnail sizing.
  • Banner (3840×1600) – wide hero/cover images.
  • Instagram DP (320×320) – profile picture cropping.

Output format tips

  • PNG – best for sharp text, logos, and transparency.
  • JPG – smaller files for photos; increase quality for cleaner results.
  • If you pick PNG, JPG quality won’t affect output.
Lock mode (best for framing):
Use Lock to freeze the crop size. You can still move the crop box around to frame the image, but resizing is disabled until you unlock.

Tip: Use the meta line under the preview to confirm the final crop size before downloading.

Troubleshooting & FAQ

Quick answers for “why is this disabled?” and “why does it look different?” moments.

Why can’t I resize the crop box?
You likely enabled Lock. Lock disables resizing so the crop stays fixed. Click Unlock to resize again.
I locked the crop size — can I still move the box?
Yes. Lock keeps the crop size fixed, but you can drag the crop box around the image to frame the area you want.
A preset is bigger than my image. What happens?
If your image is smaller than the preset dimensions, the tool automatically applies a scaled version of that preset that fits inside your image while keeping the same aspect ratio.
The downloaded image looks slightly soft. Why?
If the crop is small (or the source image is low-res), the result can look softer. Try a higher-resolution source image, choose PNG for sharp graphics, or increase JPG quality.
My crop dimensions don’t match what I expected.
Check the “Crop: w=…, h=…” line below the preview — that is the real output size. If Lock is enabled, unlock before changing size. Otherwise, use Apply size for exact pixels.
Why is JPG quality disabled sometimes?
JPG quality applies only when output format is JPG. If you select PNG, the quality field is disabled.
Is my image uploaded anywhere?
No. Cropping happens in your browser. The tool does not upload your image to a server.

Tip: If something feels “stuck”, try Reset — and make sure Lock is off when adjusting size.

Quick glossary

A few terms you’ll see while cropping and exporting.

  • Pixels (px) – the exact width/height of your crop.
  • Aspect ratio – width-to-height relationship (e.g., banners are wide).
  • PNG – best for sharp edges, logos, and transparency.
  • JPG quality – higher = clearer image but larger file size.
