Step 2 / Output

Set the maximum canvas

The complete image fits inside your chosen dimensions and keeps its original proportions.

Social size preset

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

Workflow guide

Right-size one asset for publishing

Use familiar social dimensions without distorting faces, products, screenshots, or typography.

What you need

Choose one supported still image. Very small images are not enlarged, which avoids inventing detail.

Social-ready choices

Presets provide common planning dimensions; platform requirements can change, so check the destination before a campaign launch.

What you receive

A proportionally resized file with the suffix _nirmion_tools_resized downloads in the selected format.

Decision guide

Resize without stretching the story

A proportional resize changes pixel dimensions while keeping every part of the source visible. It is the safer choice for logos, screenshots, diagrams, and images where edge content matters.

The social presets are maximum boxes, not forced canvases. A landscape source placed in a square preset remains landscape, which prevents distortion but may leave the destination platform to add padding or crop later.

Where resizing fits

Prepare a high-resolution photograph for a website content column.
Reduce screenshot dimensions while preserving the complete interface.
Create a smaller logo or graphic without cutting off edge details.

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.
