A square stamp is the one to use when the content is lines of text rather than a name around a ring. Everything sits straight, which means it stays readable at small sizes where curved text starts to fight itself.

Frequently asked questions
Square or round, which should I use?
Round for a company seal, where a name around a ring is the convention. Square for anything that is mostly lines of text: an address, an approval with a signature line, an inspection record.
How much text fits on a square stamp?
Four to six lines reads comfortably. Past that the type has to shrink to a size that will not survive being printed and scanned.
Can a square stamp have a logo?
Yes, either above the text or beside it. Keep it to one, because a square has no ring to separate the elements the way a round seal does.
Is the stamp maker free?
There is no charge to make a a square stamp, no account needed, and no watermark on what you see. The charge is for the file, $1.50 for one format or $3.00 for the complete set.
Do I need to install an app?
No. It runs in the browser on a phone, a tablet or a desktop, with nothing to install and nothing to update.
Can I put the stamp on a PDF?
Download the transparent PNG and drop it onto the page in your PDF editor. There is also a tool here that puts the stamp onto the PDF for you, included with a plan.
Can each stamp carry its own number?
Save a square stamp to your library and it gets its own counter. Tick the numbering option at download and that file takes the next number in the sequence, incremented under a row lock, so two tabs or two devices cannot be handed the same one.
Is there a free maker, or only samples?
This is a free square stamp maker. Pick a square stamp sample for a head start or use the blank square stamp generator, then change every line of the square stamp design. Everything happens with the square stamp online in your browser. The square stamp price is per file rather than monthly, $1.50 for a square stamp png and $3.00 for the pack, and a square stamp template never enters into it.
Estamplab is a design tool. What a notarial or legal mark must carry is set by the authority that issued the commission or the appointment, and it differs sharply between jurisdictions, so check your own paperwork before relying on any layout here. This page describes common practice rather than giving legal advice. Only produce a mark you hold the authority to use: a stamp in the name of an office you do not hold is forgery.
