Features
Everything a seller or creator needs
One page, no account, no installs. Set it up once and Postmark remembers your look next time.
Your text or logo
Use your page name, your logo, or both, in 12 lettering styles with effects like outline, glow, neon and 3D. Put it in a corner, make it big and faint, or repeat it so it's hard to crop out.
Price tags and SOLD stickers
Add a price, plus SOLD, AVAILABLE, RESERVED, NEW or SALE. Give each photo its own price in a tap.
QR code and contact line
Put your number on every photo, and a QR code that takes buyers straight to your page or shop.
Right size and shape
Large, small or original size. Crop to square for shop listings or tall 4:5 for social feeds.
Private by design
Everything happens in your browser. Your photos are never uploaded to any server, not even ours.

FAQ
Questions people ask
Is it really free?
Yes. No sign-up, no limits and no Postmark branding on your photos. If it helps you, you can leave a small donation inside the app.
Are my photos uploaded anywhere?
No. Postmark runs entirely in your browser. Your photos stay on your device, and you can watermark them without anyone else seeing them.
Does it work on my phone?
Yes. It works in any modern browser on Android, iPhone, tablets and computers.
Which photos can I use?
JPG, PNG, WebP and most other photo files, in any shape. Your downloads are high-quality JPGs.
Will my original photos be changed?
No. Postmark makes watermarked copies. Your originals stay exactly as they were, so keep them if you ever need a clean version.
