Files decode in this page, render to canvas, and never upload by default. Canvas export strips EXIF metadata.

How it works

01 · Method

How the result is calculated

Upload or configure the asset locally in the browser, choose a platform preset, preview the result, then export or continue into SignalDeck only after the useful output exists.

02 · Practice

Best practices

  • Keep browser-local processing as the default unless you explicitly choose to save.
  • Use the output as a working draft and review it before publishing.
  • Keep campaign source, platform, and result context attached when moving into SignalDeck.
  • Do not treat estimates, suggestions, or previews as official platform data.

03 · Examples

Worked examples

  • Campaign creative: Downloadable creative files sized for the selected platform, processed locally by default.

Questions

What is Social Media Image Resizer?

Social Media Image Resizer is a free ToolDeck utility built to solve the task on this page first, then connect the result to a relevant SignalDeck workflow when you choose to continue.

Are uploaded images sent to a server?

No. Image tools should process files in the browser by default and only save files when you explicitly choose a save workflow.

Can I use the exported file without signup?

Yes. Export and download actions should work before signup, with an optional SignalDeck CTA after the useful result.
