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

The dotted crop box can be moved freely to pick the exact part of the image you want. If you set a width/height (or choose a preset), the crop box is resized to match those pixel values as closely as possible, then you can reposition before downloading.

  • Preset sizes: pick common dimensions (poster, banner, thumbnail, Instagram DP).
  • Exact pixels: enter width/height and click “Apply size”.
  • Lock mode: freeze crop size and only move the box around the image.
  • Instant export: download the cropped area in PNG or JPG.

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

Practical guide

When to use presets

  • Poster (750×1125) — fast crops for poster-style artwork.
  • Video Thumbnail (1628×1000) — ideal for platform thumbnails.
  • Banner (3840×1600) — wide hero images and cover banners.
  • Instagram DP (320×320) — profile picture cropping.

Lock mode (best for framing)

Use Lock when you want the crop size to stay fixed. You can still drag the crop box around to frame the image, but resizing is disabled until you unlock.

Output format tips

  • PNG — best for sharp text, logos, and transparency.
  • JPG — smaller file size for photos (use a higher quality for cleaner results).

Best-results checklist

  • Start with a high-resolution image if you need crisp results.
  • If a preset is larger than your image, the tool will apply a scaled version that fits.
  • Use the meta line under the preview to confirm your final crop size before downloading.

Troubleshooting & FAQ

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, but can I still move the box?
Yes — that’s the point of Lock. The crop size stays 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 using 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 to force exact pixels.
Why is JPG quality disabled sometimes?
JPG quality only applies 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

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