Logo Diffusion exports logos as a layered SVG with real vector paths, plus a transparent PNG. The SVG comes from Vectorize: upload any logo image, or send a logo you made in Logo Diffusion there, and convert it. This guide takes one logo through every step, Brain Spark from the Logo Diffusion gallery: what each vectorizer costs and returns, the download, and how to check the file before it goes to a printer or a developer.
Start with step 1: open Vectorize in the top menu of the app and upload your logo.
What an SVG File Is
SVG (Scalable Vector Graphics) describes a logo as shapes and curves written in code. A PNG or JPG stores a fixed grid of pixels. Scale a PNG up and the edges blur. Scale an SVG up and the browser or printer redraws the curves at the new size, so the edges stay sharp.
That is why the master copy of a logo should be an SVG:
| Feature | What it means for a logo |
|---|---|
| Scales to any size | One file works for a favicon and a billboard |
| Small file size | Flat logos with solid colors load fast on a website |
| Text-based code | Colors and shapes can be changed in any vector editor |
| Resolution independent | Sharp on phone screens, high-density displays and print |
Step 1: Upload Your Logo to Vectorize
Click Vectorize in the top menu and upload your logo as a PNG or JPG. Any logo works: one you made in Logo Diffusion, an old file from a past designer, or a photo of a printed logo. Uploading costs nothing. Credits are charged when you convert in step 2. A logo you made in Logo Diffusion also has a Vectorize button under the result, which opens it here.
Start from the largest, sharpest copy you have, with strong contrast and clean edges. If the logo sits on a photo or a busy background, remove it first with Background removal (2 credits), then upload the transparent PNG.
Make your logo with Logo Diffusion. Describe it, sketch it or upload an image, then turn it into a layered SVG with Vectorize. Try it for free.
Step 2: Choose the Default or HQ Vectorizer
Vectorize has two options. Pick one, then start the conversion.
| Default vectorizer | HQ vectorizer | |
|---|---|---|
| Cost | 5 credits | 8 credits |
| Plans | All plans | Paid plans |
| Files you get | Stacked | Stacked and Cut out |
| Gradients | Kept | Not supported |
| Best for | Logos with gradients and color blends | Small text, fine detail, and cut paths for print, vinyl or embroidery |
Stacked places shapes in layers, one on top of another, so enclosed areas stay filled behind. Use it for websites, documents and most print jobs.
Cut out cuts every hole all the way through, so each shape stands on its own with nothing hidden underneath. Vinyl cutters, embroidery software and screen printers need those separate outlines.
When the conversion finishes, the page shows your original and the vector in one frame with a slider. Drag it across the logo and check small text, thin lines and curves before you download.
On the free plan, Vectorize is limited to 2 a month with the Default vectorizer. If you made a Default vector and later need a Cut out file, vectorize the logo again with HQ for 8 credits.
Step 3: Download the SVG
Click Download under the result. After the Default vectorizer you get the Stacked SVG. After HQ, the menu offers the Stacked file and the Cut out file. Download either or both: the second file costs nothing extra.
Name each file with the brand, the version and the color, for example "brainspark-color-stacked.svg". Nobody should have to open a file to know what it is.
Step 4: Or Download Straight From a Logo You Made
Logos you make with Text to Logo, Sketch to Logo or Image to Logo download as a PNG: open the result and click the download icon. For the SVG, click Vectorize under the same result and follow steps 2 and 3.
Paid-plan downloads are unwatermarked: a 1024 px PNG from the download icon, and the layered SVG from Vectorize. Free downloads are 512 x 512 and watermarked.
Take the SVG for your website, print and signage. Take the transparent PNG for places that only accept image files, like social profile pictures and some email tools.
Step 5: Check the Paths Before You Send the File
Drag the SVG into a new browser tab and zoom in close. The edges should stay sharp at every zoom level.
To see the layers, right-click the logo and choose Inspect. Each shape in the file is a separate path element. That is what "layered" means in practice: open the SVG in any vector editor, select one shape, and change its color, move it or delete it while the rest of the logo stays as it was.
SVG Hygiene Before the File Leaves Your Hands
These checks apply to any SVG logo, wherever it was made.
- Keep text as shapes. SVG text needs the font installed on the computer that opens it, or another font takes its place. A vectorized logo already has its lettering as shapes. If you add a tagline in an editor, convert it to outlines before you export.
- Keep the viewBox. The viewBox attribute lets the SVG resize with its container. Some editors drop it on export, and the logo then stops scaling with the page.
- Cut the node count. Very dense paths make a heavier file and can render with wobbly edges. Simplify paths in your editor and delete hidden or duplicate shapes.
- Remove what the logo does not use. Editor metadata, empty groups and unused layers add file size and nothing else.
- Lock the colors. Write down the hex values of your logo colors and check the SVG uses exactly those. Semi-transparent shapes that overlap change color where they meet, so avoid them.
- Test it. Look at the logo on a light and a dark background, in two or three browsers, at favicon size and at full width.
Then file it. One folder for the master files, one for web (SVG and PNG), one for print. Add a version number to every file name so an update never overwrites the copy someone else is using. For sizes per platform, see the logo size guidelines, and for the full hand-off list, the checklist for exporting production-ready logos.
Which File to Use Where
| Use | File |
|---|---|
| Website header, favicon, app | SVG, with a transparent PNG as a fallback |
| Social profile pictures | Transparent PNG |
| Business cards, packaging, signage | SVG (Stacked) |
| Vinyl, embroidery, screen printing | SVG (Cut out, from the HQ vectorizer) |
| A printer asks for PDF or EPS | PDF and EPS export is coming soon. Until then, open the SVG in a vector editor and save it in that format. |
If you are deciding between a vector file and a bigger PNG, vectorization vs raster upscaling explains when each one fits. To convert a logo now, go to the Logo Diffusion vectorizer.
FAQ
In Logo Diffusion, the SVG comes from Vectorize. Upload the logo there, or click Vectorize under a logo you made, convert it and download the SVG. In a vector design app, SVG is listed under Export or Save As.
Upload it to Vectorize in Logo Diffusion. The Default vectorizer costs 5 credits and returns a Stacked file. The HQ vectorizer costs 8 credits on paid plans and returns a Stacked file and a Cut out file. Start from the sharpest copy of the logo you have.
A Stacked file places shapes in layers, so enclosed areas stay filled behind. A Cut out file cuts every hole through, so each shape stands alone. Use Stacked for screens and most print, and Cut out for vinyl, embroidery and screen printing.
SVG is better for websites, apps and print, because it stays sharp at any size. PNG is for places that only accept image files, like social profile pictures. Logo Diffusion exports both, and the PNG has a transparent background.
Logo Diffusion exports SVG and transparent PNG. PDF and EPS are coming soon. If a printer asks for one of them today, open the SVG in a vector editor and save it in that format.
SVG text needs the font installed on the computer that opens it. If the font is missing, another font replaces it. Convert text to outlines before you export. A vectorized logo already has its lettering as shapes.
The Default vectorizer costs 5 credits and the HQ vectorizer costs 8 credits. HQ is on paid plans only. The free plan includes 2 vectorizations a month with the Default vectorizer. Downloading both files of one result costs nothing extra.
