WhatsApp DP Size Maker
Built for a WhatsApp display picture (DP). This tool crops your photo to 640×640px (square 640×640), keeps the file between 20KB and 500KB, and can auto-set a plain light background — the exact combination WhatsApp looks for.
WhatsApp photo specification
- Size: 640×640 px — square 640×640
- File size: 20KB – 500KB
- Background: any plain background
- Format: JPEG
Common rejection reasons
- Background isn't plain — shadows, patterns or other people in frame.
- Photo older than the window the form allows (usually 3–6 months).
- File size outside the 20–500KB band — either too small (looks pixelated) or too large (upload rejected).
- Face not centred or too much/too little headroom above the head.
How to get it right the first time
Start from a recent, well-lit photo taken against a plain wall. Upload it here, let the tool crop to 640×640px and set the background, then download — the file will already sit inside the 20–500KB band, so there's nothing left to adjust manually.
How it works
Frequently asked questions
What exact size does WhatsApp need?
640×640 pixels (square 640×640), between 20KB and 500KB.
Can I use a photo I already have on my phone?
Yes, as long as it's recent, front-facing and reasonably well lit. Upload it and the tool handles the cropping, background and file size for you.
Is my photo uploaded to Toolzo's servers?
No. The crop, resize and compression all run inside your browser tab — the photo never leaves your device.
