Why this runs in your browser, not on a server

A meme is often a quick, throwaway thing — not something you want sitting on a stranger’s server. Altto skips that step completely — there’s no server for it to go to.

Nothing is uploaded, everYour image is captioned by code that runs in this browser tab, because there’s no server on the other end. That also means we can’t see it, copy it or keep it.
No account, no email wallMake as many memes as you like without signing up or handing over an email address.
No watermark or brandingEvery image you download is yours to use, free of any Altto marks.

images stored on our servers. There’s no server involved at all — everything happens locally, every time.

FAQ

Frequently asked questions

The practical details on what this tool can and can’t do. Want to turn several images into a GIF instead? See GIF Maker.

Is my image uploaded anywhere?

No — nothing is ever uploaded. Your image is drawn and captioned entirely inside this browser tab, on your device. There's no server involved at all, so we never see it, copy it or keep it.

What font does this use?

Impact, the classic meme font, with a fallback to a similar bold sans-serif on devices that don't have it installed.

Can I move the text anywhere on the image?

Not yet — captions are placed at the top and bottom, in the traditional meme layout. Leave either box empty if you only want one caption.

What size and format is the download?

A PNG at your original image's resolution (capped at 1000px wide to keep file sizes sensible), with the captions baked in.

Can I use this commercially?

Yes — everything happens on your device and there's no watermark or licensing restriction from Altto. You're responsible for having the rights to any image you upload.

Do you keep a copy of what I make?

No. There's no upload, so there's nothing on our side to keep. See the Privacy Policy for details.
