Image Cropper

Create exact social-media dimensions with a focal-point crop that keeps the important subject in frame.

Runs locallyNo image upload to Nirmion

Step 1 / Source

Choose one image

JPEG · PNG · WebP · 20 MB

Drop your image here

Or browse for a JPEG, PNG, or WebP image that you own or are authorised to edit.

One file · up to 20 MB · maximum 50 megapixels

Step 2 / Output

Frame the subject

The tool removes excess edges to fill the exact target dimensions without stretching the image.

Social size preset

Choose a common publishing canvas, then fine-tune the dimensions if needed.

Crop focus

Move the focus toward the subject you want to retain when the edges are removed.

01No server upload

The selected image is decoded and re-encoded inside this browser tab.

02Working copy released

After download, the preview URL, decoded bitmap, canvas, and selected source reference are cleared.

03Your download remains

Nirmion cannot remove the finished file from your device or browser download history.

Workflow guide

One crop, a deliberate focal point

Turn a source image into a full-bleed social canvas while choosing which part survives the crop.
A

What you need

Use an image with enough resolution around the subject for the chosen portrait, square, story, or landscape frame.

B

Social-ready choices

Story and reel interfaces often cover top and bottom areas. Keep essential text and faces away from those edges.

C

What you receive

An exact-size image with the suffix _nirmion_tools_cropped downloads and the source working copy is released.

Decision guide

Frame for the interface, not only the photograph

Social platforms place captions, avatars, buttons, progress bars, and navigation over media. The inset guide is a planning aid for keeping essential content away from vulnerable edges.

The live preview uses the selected focal percentage and target aspect ratio. The downloaded output is produced independently by canvas geometry, so review that final file before a scheduled campaign or paid placement.

Where exact crops matter

  1. Turn one landscape campaign image into a portrait feed asset.
  2. Frame a face or product for a 9:16 story or reel cover.
  3. Create consistent square catalogue or profile-grid imagery.

Good to know

Important image boundaries

Why might a PNG not become smaller?
PNG is lossless and browsers do not expose a quality control for it. Choose WebP or JPEG when reducing file size matters more than exact lossless pixels.
Are animated images supported?
No. The workspace accepts still JPEG, PNG, and WebP files. Re-encoding an animated source would otherwise keep only one frame.
What does clearing the file mean?
Because processing is local, there is no Nirmion server copy to delete. The tab releases its working references after success; your downloaded output remains on your device.
