| Task | Start with | When it helps |
|---|---|---|
| Keep only selected PDF pages | PDF Split | Enter page ranges and download a smaller PDF without uploading the source file. |
| Change an image's frame, size, or format | Image tools | Crop first, resize second, and convert only when the destination requires another format. |
| Estimate maintenance calories | TDEE Calculator | Start with BMR, add an activity factor, and review the limitations before adjusting food intake. |
| Compare products with different package sizes | Unit Price Calculator | Normalize weights, volumes, or item counts instead of comparing shelf prices alone. |
| Estimate a loan payment or tank capacity | Everyday calculators | Use focused inputs and review the units, rate, term, and exclusions shown with the result. |
| Plan a trade or compare investment yield | Investing calculators | Separate position risk, weighted cost, dividends, and bond yield instead of treating them as one metric. |
| Clean, count, style, or encode text | Text tools | Choose a focused operation and review the output before replacing the original text. |
| Pick a fair random result | Random tools | Choose folded slips, numbers, dice, a wheel, or groups based on the result format you need. |
The interactive tool stays near the top of each tool page. The longer SEO content is placed below the tool so users can finish the task quickly and continue reading only if the examples are useful.
