AltF Signals rates "resize image" at 79 out of 100 on AltFTool's own editorial opportunity scale, against no sourced search-volume estimate and high competition. AltFTool ships this: the Image Resizer sets exact pixel sizes or a percentage, has social media presets, and can fit, crop or stretch to the target before exporting JPEG, PNG or WebP. It handles up to 20 images of up to 35 MB each, all in the browser, and does not upload them.
Social media managers, online sellers and anyone filling in a form that demands an image at a specific size.

| Figure | Where it comes from |
|---|---|
| Opportunity score | AltFTool editorial judgement on a 0-100 scale. It is not measured, not audited and not a prediction of commercial success. |
| Search estimate | A directional third-party monthly estimate where one is recorded. Where none is, it reads Not estimated rather than showing a made-up number. |
| Competition and momentum | Editorial labels, not metrics from an SEO platform. |
| Relative search interest | The only live figure on this page, fetched from Google Trends when you load it. A 0-100 relative index, not absolute volume. |

Fit keeps the whole picture and pads the space around it with a background. Fill crop covers the exact canvas and trims whatever overflows, which suits fixed slots such as profile photos and story frames. Stretch forces the exact size and distorts the picture if the shape differs.
