How do I stamp my WhatsApp number on product photos before sending them to customers?
Type the number into the watermark text field, keep 'Bold' and the outline switched on, and make it large enough to read on a phone screen after the chat app compresses the photo. A number made only of digits is drawn left to right in the right order. If you add an Arabic word before it, check where the + ends up in the preview.
Why put the number on the photo at all
Product photos you send on WhatsApp get forwarded from customer to customer and land in groups you never see. A photo that carries your number brings the new customer straight to you instead of leaving them asking where it came from. The number is also a mark of ownership: anyone who copies the photo into their own shop carries your number with it.
Make it readable after the chat app compresses it
Chat apps may shrink and compress a photo when it is sent, and small thin digits are the first thing to smear. So a number needs a larger size than a decorative word would:
A photo 1080 px wide with the number 0501234567 at size 40%: the line is drawn 432 px wide, roughly 40 px per digit.
The tool sets this text to run left to right, because it contains no Arabic letter.
The text 'واتساب 0501234567' starts with an Arabic letter, so the line runs right to left, but the number itself keeps its correct order.
- Bold makes the digits thicker so they hold up better under compression, and it is on by default.
- The outline beats the shadow for digits, because it separates each one from the background with a clean line.
- An opacity of 70% to 90% suits a number better than the low values used for decorative marks; the point here is to be read.
The + sign in an Arabic line
If you type 'واتساب +966501234567', the + may appear at the other end of the number, because it is a neutral symbol in a right-to-left line. Simple fixes: start the line with the number and put the Arabic word after it, write 00966 instead of +966, or drop the word and use the number alone. Either way, the preview is your reference.
Steps
- Open the Image watermark editor tool and choose your product photos, up to 30.
- Type the number as the watermark text, and keep 'Bold' and 'Outline'.
- Set the size between 35% and 45%, and pick bottom center or bottom right with a margin.
- Download, then send one photo to yourself on WhatsApp and open it on your phone to confirm the number reads after sending.
Remember that a number on a photo cannot be tapped. The customer has to type it or copy it by hand. Send a direct chat link alongside that opens WhatsApp with a ready message; you can make one in seconds with the WhatsApp link generator and put it in your bio or product message.
Common questions
Should I write the number in Arabic-Indic or Western digits?
Western digits are easier for a customer to copy into the dialler. The tool also treats Arabic-Indic digits like Arabic letters when it sets the direction.
Can I put the number and the shop name together?
Yes, on one line of up to 120 characters. But a longer line means smaller digits at the same size, so raise the size.
Can the number sit on a line under the shop name?
Text is a single line only. For two lines, design them as a transparent PNG and upload it as the logo.
