Is my photo uploaded to a server?

No. Cropping and resizing happen entirely in your browser using the Canvas API. Your photo never leaves your device.

What is WhatsApp's display picture size?

WhatsApp stores uploaded display pictures at 640x640 pixels, which is what this tool exports. You can upload a larger image directly in WhatsApp and it will downscale it, but exporting a clean 640x640 square here gives you control over the crop before that happens.

Why is the guide a circle if the download is square?

WhatsApp displays every DP as a circle in chats, calls, and contact lists, but the file you upload is a square. The circular guide shows what will stay visible after WhatsApp applies its circular mask, so corners of the square may get trimmed.

What file format does this export?

A PNG file. WhatsApp also accepts JPEG for a display picture, so a static PNG works fine and avoids extra compression before you upload it.

Does this tool fix lighting or background?

No. It only crops and resizes to the correct square dimensions. Start from a photo that already looks the way you want, since this tool does not edit color, brightness, or background.

Can I use this for a WhatsApp Business profile photo?

Yes. WhatsApp Business profile photos use the same square-cropped-to-circle display, so a 640x640px export works for either a personal or business account.

Summary

WhatsApp DP Resizer crops any uploaded photo into a square and exports it at 640x640 pixels, the size WhatsApp stores display pictures at once you upload one. Drag to reposition and use the zoom slider to fit the important part of the photo inside the circular guide, since WhatsApp shows every DP as a circle in chats and contact lists even though the underlying file is square. WhatsApp accepts larger source images and downscales them itself, but exporting a clean 640x640 square here avoids uneven compression and lets you control exactly what gets cropped before it ever reaches the app. The crop, resize, and export all happen locally in the browser canvas, so the photo never leaves your device before you click download.
