Resize stamp
Scale a stamp image to exact pixel sizes.
Resize stamp scales a seal to exact pixel width and height when a portal, form or printer needs a fixed size. Keep aspect ratio locked for round seals so they stay circular.
Resize stamp FAQ
How do I resize a stamp to exact pixels?
Upload the PNG, enter width and height (or lock ratio and set one side), preview, then download the scaled image.
Will resizing make my round seal look oval?
Not if you keep aspect ratio locked. Unlocking width and height independently can stretch the seal — avoid that for circles.
What size works for email letterheads?
Many people export around 300–600 px wide for on-screen docs. For print, prefer a higher-resolution PNG from the stamp editor at 2× or 3×.
Is Resize free to use?
Yes. Free, no account, and the output has no watermark.
Can I enlarge a tiny scan without blur?
Enlarging adds softness. Prefer regenerating from the vector editor or SVG when you need a much larger seal.
