Single images are the bread and butter of Krumzi: Instagram posts, ads, YouTube thumbnails, LinkedIn graphics, banners, quote cards. Describe it, pick a size, send. Here's the full flow.

Before you begin

  • Image design is available on every plan, including the trial.

  • Credits are usage-based: you're charged after the turn for the work the AI actually did. A first generation costs more than a small tweak; complex briefs cost more than simple ones.

Generate your image

  1. Open AI Designer from the sidebar.

  2. Make sure Image is selected in the type selector.

  3. Pick a size. Open the size picker to see 44 presets grouped by platform (Instagram, Facebook, LinkedIn, X, YouTube, TikTok, Discord, Pinterest, Bluesky, Product Hunt), each with a little aspect-ratio icon and its pixel dimensions. Or use the custom size bar at the bottom to type any width and height, with an aspect-ratio lock and an orientation swap.

  4. Set your options. Choose a model, leave Think on for a rich brief, toggle Brand Kit if you have one, and attach any photos or logos you want placed.

  5. Describe the design and send. For example:

New seasonal menu post for a coffee shop. Headline "Fall Flavors Are Here", subtext "Pumpkin Spice · Maple Latte · Cinnamon Mocha". Warm, cozy, one big latte photo.

What you'll see

Krumzi opens the editor and the AI gets to work in the side panel. You'll watch it plan the concept, then add elements to the canvas step by step (headline, image, shapes, background), then check its own work for overlaps, contrast, and safe areas before it wraps up. You can press Stop at any point and keep whatever it's built so far.

What the AI can put on the canvas

  • Text with real typography choices from the full Google Fonts library, including mixed-weight headlines.

  • Images: your uploads, stock photos, AI-generated artwork (5 credits per image), or real images pulled from a URL you pasted. Any image can get its background removed (5 credits) or be clipped to a circle, pill, arch, or blob.

  • Shapes, icons, emojis, QR codes, and annotations like arrows and highlights.

  • Backgrounds: solid, gradient, mesh, transparent, or a full-bleed photo with an overlay for legibility.

  • Effects: shadows, glows, blur, glass, filters, and blend modes.

Every one of those is a normal editable element afterward. Nothing is baked into a flat image.

After generation

Refine in chat

Keep talking: "make the headline bigger", "try a darker background", "move the logo bottom-right". From your second message onward, changes the AI makes show up as pending with a purple outline, and you keep or discard them, one by one or all at once. See "Refine Your Design".

Edit by hand

Click any element to move, resize, restyle, or delete it. The editor gives you exact control when you want it.

Export

Hit Export and choose PNG, JPG, WebP, or PDF, at 1× to 4× the canvas size, with an optional transparent background for PNG and WebP.

Tips

  • Give the AI your real headline. It designs around the words, so placeholder copy produces placeholder layouts.

  • Attach the actual product photo instead of describing it. The AI can see it and place it.

  • Making several posts in one style? Turn on Batch and let the AI produce up to 10 variations from one brief.

  • Set up Brand Mind once and every image starts on-brand without you repeating colors and fonts.
