Seedream is one of the named image models on CanvaPro, and the live form gives you more control than a prompt box alone. The free Seedream image generator offers Text to Image and Image to Image, two Seedream models, and a visible size picker. You do not need an account, and the usual download does not pick up a watermark from the page.
Image to Image accepts a JPG, PNG, or WEBP up to 10 MB. That path is on the live form, even if older page copy once described the tool as prompt-only. The models are Seedream 5 Lite (the default) and Seedream 5 Pro. Sizes are 1K, 2K, and 4K, with 2K selected by default. Aspect ratios are Auto, 1:1, 3:2, 2:3, 9:16, 16:9, 3:4, and 4:3. After you write a prompt, complete the security check and click Generate Image. A preview typically appears in about a minute.
Lite, Pro, and the size you pick
If you are comparing the two models, change only the model between runs so the difference is clear. Use 1K for a faster draft, 2K for a standard still, and 4K when you want more room for detail. Set the size and the aspect ratio before you generate, rather than cropping a finished file to fit the channel.
If you specifically need a 4K still and a different form, see how to generate a 4K image from text.
How to generate or edit a still, step by step
- Choose Text to Image or Image to Image. In Image to Image, upload a JPG, PNG, or WEBP under 10 MB, and only use a file you have the right to edit.
- Pick Seedream 5 Lite or Seedream 5 Pro, then pick 1K, 2K, or 4K and an aspect ratio.
- Write a prompt that names the subject, setting, light, and style. In Image to Image, say what should change and what should stay.
- Complete the security check, click Generate Image once, and review the preview before you download.
Prompts and practical uses
A quiet interior, a product still, or a cinematic landscape usually holds together better than a prompt packed with conflicting styles. Creators use Seedream for concept stills and social drafts. Teams use Image to Image to explore a variation of a photo they already own. Treat every result as synthetic media, and label it when a client or platform needs that context.
If the still looks off
Simplify the prompt, confirm the 10 MB limit in Image to Image, and try the other model or a different size. A busy moment can add a short wait. If you specifically want typography-led stills on a similar form, switch to the Ideogram image generator and run the same idea there for a second pass.
Uploads and prompts travel over HTTPS. Requests are handled to complete generation and are not sold. Only upload reference photos you have the right to use.
If you specifically need a 4K canvas and a different form, try the 4K image generator rather than forcing a smaller Seedream size.
After the Seedream preview appears
Judge the image at the size and aspect you will actually use. If the composition is close, change one variable — the model, the size, or a single phrase — and generate a new still, rather than heavily editing a near-miss. Save the file with a note of Lite or Pro, the size, and the prompt so you can recreate the result later.
Check detail at 100 percent, and if the brief missed, tighten the prompt and generate again with the Seedream generator from the same settings you meant to use.
When to use Lite, Pro, and each size
Lite is a sensible default when you are exploring a prompt and you want a preview quickly. Pro is worth a second pass when the composition is already close and you want to see whether the other model holds materials or faces more carefully. Because 2K is the default size, many everyday posts never need a change. Switch to 1K if you are iterating on wording, and step up to 4K once you like the idea and need more room for detail or print.
Image to Image should start from a reference you are allowed to change. A product still, a room you photographed, or a layout you designed are fair uses. A stock photo you do not have the right to edit is not. Say what to keep so Seedream does not restyle the entire frame by accident.
Keep a simple log of model, size, aspect, and prompt next to each download. Seedream stills can look similar across runs, and that log is what lets you recreate the one you actually want to publish.
Locked, photo-anchored edits are often a better fit for the walkthrough to generate or edit images with Flux Kontext.
A short checklist
- Pick Text to Image, or Image to Image with a JPG, PNG, or WEBP under 10 MB.
- Choose Seedream 5 Lite or Pro, plus 1K, 2K, or 4K, and an aspect ratio.
- Click Generate Image once and wait about a minute for the preview.
- Download the still you like, and keep earlier versions for comparison.
When you are ready, set the model and size first, describe one clear scene, and save the preview only after it looks right. A single considered still is easier to publish than a folder of almost-identical experiments.
