How do I edit an image with Rastera Studio?

Open the editor, choose a template or a blank canvas, then upload an image and add text or shapes as layers. Adjust color, opacity, rotation and effects in the properties panel, reorder layers, and click Export to download PNG, JPEG, WebP, AVIF, SVG or PDF. It is free and runs entirely in your browser, so your image is never uploaded.

Are my images uploaded to a server?

No. Editing, templates, AI inference, autosave and export all run locally in your browser; images never leave your device. There is no upload endpoint — you can verify it in the browser DevTools Network tab.

Is the editor free and does it require an account?

Yes, it is free to use and requires no account or sign-up, with no limit on the number of designs. Projects are stored on your own device or downloaded as .rastera files. The site is ad-supported.

Which export formats are supported?

PNG, JPEG, WebP, AVIF where the browser supports it, SVG, standard PDF, and print PDF with millimetre bleed and optional crop marks — plus the editable .rastera project format.

Does it work offline?

Yes. Once the page has loaded, the editor needs no server connection. The AI models are served from the same origin and cached, so background removal, upscaling and OCR keep working after you disconnect.

Does it work on phones as well as desktop?

Yes. Phones get a five-action bottom bar with a touch sheet for panels, while desktop shows the tool rail, canvas, properties and layers side by side.

Is there a file size limit?

No artificial limit. The practical limit is your device memory, since the whole document is held in the browser. Very large canvases or many high-resolution layers take longer to render and export.

Can I use the designs commercially?

Yes. The templates are original to this project, and the editor dependencies and bundled AI models use permissive commercial-use licenses recorded in the project third-party notices.

Online Image Editor & Design Maker

Rastera Studio is a free browser-based image editor and design maker that combines layers, multi-page documents, 60 editable templates and on-device AI in one workspace. You can add images, text and shapes, apply effects, run background removal, upscaling or OCR locally, then export PNG, JPEG, WebP, AVIF, SVG, standard PDF or print-ready PDF with bleed and crop marks. Every step runs on your device via the Canvas API — no upload, no account, and it keeps working offline once the page has loaded.

Design, edit and export complete images in your browser — free, no upload required.

100% Free — Forever. No fees, ever.
Private: files are processed locally in your browser and never sent to a server.
No upload, no account, no sign-up.

Open the editor
Go to the Rastera Studio page. No sign-up, plugin, or installation required — the editor loads straight into your browser.
Start from a template or a blank canvas
Pick one of 60 editable templates across social, story, promotion, collage, business and poster categories, or set your own canvas size and start empty.
Build your design with layers
Upload images, add headings and shapes, draw freehand, then reorder layers and adjust color, opacity, rotation and effects. Add more pages for multi-page documents.
Export or save the project
Download PNG, JPEG, WebP, AVIF, SVG, standard PDF or print PDF with bleed and crop marks — or save an editable .rastera project to keep working later.

Rastera Studio ships 60 original, editable templates across six categories: social, story, promotion, collage, business and poster.
Projects use a versioned, renderer-independent schema saved as .rastera, so a saved design stays portable and re-editable.
AI model selection adapts to the device — available memory, CPU cores, WebGPU support, network conditions and screen class all feed the choice.
Print PDF export supports millimetre bleed and optional crop marks, the two things a commercial printer needs beyond a plain PDF.
Because nothing is uploaded, editing starts the instant a file is selected — there is no network transfer or server queue, verifiable in the browser DevTools Network tab.
