FAQ
Paid stamp questions
How do I add a PAID stamp to an invoice photo?
Take a photo of the bill or screenshot the invoice, upload it to this tool, adjust the stamp position, size, and ink opacity, then download the stamped PNG or PDF. Everything happens on your device.
Is my invoice uploaded anywhere?
No. The stamping runs entirely inside your browser using canvas. Your customer invoices, bills, and receipts never leave your phone or laptop, and nothing is stored after you close the tab.
Can I change the stamp text instead of PAID?
Yes. Type any text up to 18 characters such as RECEIVED, SETTLED, CANCELLED, VERIFIED, or DUPLICATE. You can also add a date line like 'Paid on 21 Aug 2026' and a signature name under the stamp.
Can I get just the stamp without an image?
Yes. Skip the upload and download a transparent PAID stamp PNG that you can overlay on documents in Word, Canva, or any photo editor.
