Convert GIF to PNG with Python — Pillow, ImageMagick & Browser

If you are already working in Python or need to automate GIF-to-PNG conversion at scale, Pillow is the standard library. If you want a scriptable command-line approach, ImageMagick is the tool. And if you need a single file converted without writing any code, a browser tool is faster than either. This guide covers all three.

Convert GIF to PNG with Python Pillow

Pillow (the maintained fork of PIL) is the standard Python image library. Install it with pip:

pip install Pillow

Single file conversion:

from PIL import Image

img = Image.open("input.gif")
img.save("output.png")
print("Converted successfully")

For animated GIFs, Pillow opens the first frame by default. The output PNG will be the first frame with transparency preserved.

Explicit frame selection:

from PIL import Image

img = Image.open("input.gif")
img.seek(0)  # Frame 0 = first frame; change to 1, 2, etc. for other frames
img.save("output.png")

Batch conversion — all GIFs in a folder:

import os
from PIL import Image

input_dir = "gifs/"
output_dir = "pngs/"
os.makedirs(output_dir, exist_ok=True)

for filename in os.listdir(input_dir):
    if filename.lower().endswith(".gif"):
        gif_path = os.path.join(input_dir, filename)
        png_path = os.path.join(output_dir, filename[:-4] + ".png")
        with Image.open(gif_path) as img:
            img.save(png_path)
            print(f"Converted: {filename}")

print("Done.")

Handling Transparency in Pillow

GIF transparency is automatically preserved by Pillow when saving to PNG. No extra code is needed for transparent GIFs:

from PIL import Image

img = Image.open("transparent.gif")
img.save("transparent.png")
# Transparency is preserved automatically

If you need to convert the GIF to RGBA mode first (useful for some image manipulation workflows):

from PIL import Image

img = Image.open("input.gif").convert("RGBA")
img.save("output.png")

The convert("RGBA") call ensures the output PNG has a proper alpha channel, which is useful if you plan to manipulate the image further before saving.

Convert GIF to PNG with ImageMagick

ImageMagick is a command-line tool available on Linux, Mac, and Windows. Install via your package manager (see the Linux post for install commands).

Single file:

convert input.gif output.png

First frame only (for animated GIFs):

convert "input.gif[0]" output.png

All frames to individual PNGs:

convert input.gif output_%03d.png

This produces output_000.png, output_001.png, etc. — one per frame.

Batch conversion in bash:

for f in *.gif; do convert "${f}" "${f%.gif}.png"; done

ImageMagick preserves transparency automatically when converting to PNG.

When the Browser Tool Is Better Than Python

Python and ImageMagick are the right tools for automated, repeatable workflows. For these situations, a browser tool is faster:

• One file, right now: Opening a Python script or terminal takes longer than dragging a file into a browser tab
• No Python environment set up: Installing Pillow requires pip and a working Python environment — not available on every machine
• Non-technical users: The browser tool has no learning curve
• Shared computers or restricted environments: No install permissions needed for a browser tool

Robin GIF to PNG is the browser option — processes files locally with no upload, handles batch conversion, and requires no setup.

Setup time (first use)	~5 minutes	~3 minutes	0 seconds
Automation	Yes (scriptable)	Yes (CLI)	No
Transparency	Preserved	Preserved	Preserved
Install required	Yes	Yes	No

Python FAQs

Frequently Asked Questions

Does Python Pillow preserve transparency when converting GIF to PNG?

Yes. Pillow preserves GIF transparency automatically when saving to PNG. No extra code is needed. If you need explicit RGBA mode, use img.convert("RGBA") before saving.

How do I convert all frames of an animated GIF to PNG with Python?

Use img.seek(frame_number) to select each frame, then save: for frame in range(img.n_frames): img.seek(frame); img.save(f"frame_{frame:03d}.png"). The n_frames attribute gives the total frame count.

Why does Pillow show an error when opening some GIF files?

Common causes: the file is corrupt, it has a non-standard GIF extension, or it is a GIF with unusual encoding. Try converting with ImageMagick as a fallback. Large animated GIFs may also need special handling — use img.seek(0) to explicitly select the first frame.

Can I use wand (Python bindings for ImageMagick) instead of Pillow?

Yes. pip install wand gives you Python bindings for ImageMagick. The API is slightly different: from wand.image import Image; with Image(filename="input.gif") as img: img.save(filename="output.png"). Both produce correct results.
