Tips that ran this week
- Convert units without guessing
Length, weight, temperature, area, volume and speed, with the conversion factor shown so you can check it.
- Convert a PDF without uploading it
Every PDF tool on Wivrix runs inside your browser, so contracts and bank statements never leave your device.
- Check a loan before you sign
The EMI calculator shows total interest alongside the monthly payment — that is the number lenders lead away from.
- Resize a photo to an exact size
Passport photos, forum avatars and upload limits all need specific pixel sizes. The image resizer does it without an account.
- Sign a document without printing it
Draw or type a signature, download it as a transparent PNG, and drop it into any document.
- Pick a winner fairly
The random picker and spin wheel makes draws visible, which matters when other people need to trust the result.
- Estimate your daily calories
The TDEE calculator turns height, weight and activity into a maintenance figure you can actually plan around.
