Which shape to pick
| Shape | Good for |
|---|---|
| Square (1:1) | Profile pictures, WhatsApp DP, Instagram grid |
| 4:5 | Instagram portrait posts |
| 16:9 | YouTube thumbnails, banners, slides |
| 35:45 | Passport and ID photos |
Cropping keeps full resolution inside the box. To also change the pixel size, use resize image afterwards.
Is it safe to upload my photo?
Your image is never uploaded. ResizeKB processes files inside your own browser using the same technology that draws images on web pages, so the photo never leaves your phone or computer. That matters for documents like passport photos, ID scans and signatures. You can even disconnect from the internet after the page loads and the tool keeps working.
