Testimonial image generator

• Square — 1080 × 1080. Instagram, Facebook, LinkedIn.
• Portrait — 1080 × 1350. The Instagram feed's tallest crop.
• Wide — 1200 × 630. X and LinkedIn link cards.
• Story — 1080 × 1920. Stories, Reels, TikTok covers.

Square is the safe default if you are posting the same card in three places. Wide is the one people get wrong: it is the link-card ratio, so it is what you want when the image sits beside a headline rather than standing alone — and it is the same 1200 × 630 an og:image wants, if you are putting the quote on a page of your own.

Cut to the sentence that carries a result. Most testimonials arrive with a warm opening and a specific middle; the middle is the post. “Our response time had halved” is a card. “Great to work with” is a card nobody stops scrolling for, at any size and in any look.

Trim, do not rewrite. Cutting an opening line is fair; tightening someone’s grammar into a claim they did not make is not, and it is the thing that makes a whole feed of praise read as invented — the same failure as letting an AI write the testimonial, arrived at one small edit at a time. Why testimonials look fake is the longer version of that argument, and how long a testimonial should be covers where to cut.

One thing an image cannot do: prove itself. A card is a picture of words, so it carries no link, no name your reader can check, and nothing a search engine can read. Post the card and keep the quote in text on your own site — the HTML generator emits that half, and where to put testimonials covers which page it belongs on. The feed half — the permission, the formats, carousels and captions — is worked through in how to use testimonials on social media.

Publishing a testimonial as an image is still publishing it. The permission you need is the same one a page on your site needs: their words, their name, and their yes — and a yes for your website is not automatically a yes for your Instagram, which is a distinction worth one sentence in the ask. Permission to use testimonials covers what to keep on file. Inside Testymo that record is stored with the submission — and the app’s Post Studio works from it: the picker offers only responses that are approved with a public yes, the excerpt is cut by clicking words on the card itself, and the download is this same kind of PNG with the caption and alt text alongside — twelve layouts, sixteen palettes, the four sizes above, one post or a whole carousel. The difference from this page is memory: the studio knows who said yes.

Is the image uploaded anywhere?

No. The card is drawn on a canvas in your browser and saved straight to your downloads folder. The quote, the name and the picture never leave the page — there is no server on this tool to send them to.

Is there a watermark?

No, and there will not be one. The image is yours; put it wherever you like, with no credit to us.

Can I use my own brand colors?

Not on this tool — the five looks are fixed, which is what keeps it one click rather than a design app. If you want the colors exactly right, the HTML generator exposes the accent, the card background and the corner radius, a Testymo widget carries your styling on the live site, and Testymo’s Post Studio draws the same card in sixteen palettes from your collected responses.

Why does the quote shrink when I paste a long one?

So it fits without cropping. Past roughly forty words the type gets small enough to lose people in a feed — that is the tool telling you to cut, not a bug.
