Transparify - Restore Transparent Backgrounds

Get transparent PNGs from ChatGPT, Gemini, Midjourney, DALL-E & more

How It Works

ChatGPT, Gemini, Midjourney, DALL-E, Flux, Stable Diffusion, Recraft, and other AI generators can't export transparent backgrounds. Standard background removers create hard edges that destroy glows and soft effects. Transparify recovers the true alpha channel mathematically - preserving every semi-transparent pixel.

The technique compares two versions of the same image: one rendered on a white background and one on black. Fully opaque pixels look identical on both backgrounds, while fully transparent pixels show the maximum difference. Everything in between reveals the true transparency.

Works with: ChatGPT, Gemini, Midjourney, DALL-E, Flux, Stable Diffusion, Recraft, Leonardo AI, Ideogram, Nano Banana, and any generator that supports background color selection. Learn more | Read the full guide

Frequently Asked Questions

Why can't Gemini/Midjourney/DALL-E export transparent PNGs?

AI image generators work by predicting pixel colors, not transparency values. They don't have a concept of "no pixel here" - every position gets a color. This is why even prompting for "transparent background" results in a solid color instead.

How is this different from remove.bg or Photoshop background removal?

Background removal tools use AI to detect and cut out subjects, creating hard edges. Transparify uses math to calculate the exact transparency of every pixel by comparing white and black background versions. This preserves glows, halos, light rays, and all semi-transparent elements that removal tools destroy.

Is my image uploaded to a server?

No. Transparify runs 100% in your browser using the Canvas API. Your images never leave your device. There's no account, no upload, and no tracking.

What AI image generators does this work with?

Any generator that lets you specify background color: ChatGPT (DALL-E 3), Gemini, Midjourney, DALL-E (API), Flux, Stable Diffusion, Recraft, Nano Banana, Leonardo AI, Ideogram, and others.

Can ChatGPT generate transparent backgrounds?

No - ChatGPT uses DALL-E 3, which generates pixel colors but not transparency data. Even prompting for "transparent background" results in a solid color. However, you can recover true transparency by generating the same image on white and black backgrounds, then processing both with Transparify.

Why does remove.bg destroy glows and soft edges?

Background removal tools make a binary decision for each pixel: keep or discard. Semi-transparent elements like glows, halos, light rays, and smoke can't survive this process - they get clipped to hard edges or removed entirely. Transparify calculates the exact transparency of every pixel, preserving all soft effects perfectly.

Does this work with Flux or Stable Diffusion?

Yes. Flux and Stable Diffusion (including SDXL and SD 3.x) both support background color specification in prompts and seed control. Generate on white and black backgrounds with the same seed and settings, then upload both to Transparify for perfect results.

What if my two images don't look the same?

If the subject shifted between renders, the result will have artifacts. Use the same seed (if supported), keep prompts identical except for background color, and use "pure white" / "pure black" to avoid off-white or dark gray backgrounds. If images are accidentally swapped, use the swap button to fix them.
