Convert PNG to GIF Online

Convert your PNG images to GIF format for web graphics, simple animations, and universal browser compatibility. GIF uses lossless compression with an indexed color palette, making it ideal for logos, icons, and graphics with solid colors. Our converter transforms your PNG files into optimized GIF images while preserving transparency where possible.

GIF supports only 256 colors per frame, so detailed images with gradients may show visible color banding. For photographs or images with many colors, PNG or WebP provide better results. GIF excels with graphics that have flat colors and sharp edges.

PNG vs GIF: Understanding the Differences

PNG supports millions of colors with full alpha transparency (varying opacity levels). GIF is limited to 256 colors with binary transparency (pixels are either fully transparent or fully opaque). This makes PNG superior for most static images, but GIF has unique advantages for specific use cases.

GIF's main advantage is animation support—multiple frames can be stored in a single file. While this converter produces static GIFs, the format remains popular for simple web animations. For static images, PNG is generally the better choice unless you need maximum compatibility with older systems.

Best Use Cases for GIF

  • Simple logos and icons — graphics with few colors and solid fills
  • Line art and diagrams — sharp edges without gradients
  • Text graphics — banners and buttons with text
  • Maximum compatibility — works in email clients and older browsers
  • Small file sizes — efficient for simple graphics with few colors

Transparency Handling

PNG supports smooth, graduated transparency through its alpha channel—pixels can be any level of opacity from 0% to 100%. GIF only supports binary transparency: each pixel is either fully visible or fully invisible. When converting PNG to GIF, semi-transparent pixels must be converted to either opaque or transparent.

This can cause visible edges around graphics that relied on smooth transparency blending. If your PNG has soft shadows or anti-aliased edges against transparency, the GIF version may show jagged edges. Consider using a matte color that matches your intended background for better results.

Frequently Asked Questions About PNG to GIF Conversion

Why does my converted GIF look different from the original PNG?

GIF is limited to 256 colors while PNG supports millions. During conversion, colors are reduced to fit the GIF palette, causing visible changes in images with gradients or many colors. Simple graphics with few solid colors convert with minimal visible difference.

What happens to PNG transparency when converting to GIF?

PNG supports smooth alpha transparency (0-100% opacity), while GIF only supports binary transparency (fully transparent or fully opaque). Semi-transparent pixels become either visible or invisible, which can cause jagged edges around soft shadows or anti-aliased elements.

When should I use GIF instead of PNG?

Use GIF when: you need simple animations, maximum compatibility with old email clients or systems, working with graphics that already have 256 or fewer colors, or when binary transparency is acceptable. For most static images, PNG is the better choice.

Can this converter create animated GIFs from PNG?

This converter creates static (single-frame) GIF files. To create animated GIFs, you need multiple source images and an animation tool. Each PNG converts to one GIF frame. For animation, specialized GIF animation software is required.

Will the GIF file be smaller than my PNG?

It depends. For simple graphics with few colors, GIF may be smaller due to efficient LZW compression. For complex images, GIF often produces larger files because it's optimized for graphics, not photographs. WebP typically beats both formats for compression.

What is dithering and why does my GIF have it?

Dithering simulates colors not in the 256-color palette by mixing available colors in patterns. It makes color-reduced images look smoother but adds visible texture. Our converter uses optimized dithering to balance quality with file size.

How do I minimize quality loss when converting PNG to GIF?

Start with PNGs that already have simple color palettes, flat colors, and hard edges. Avoid gradients and photographs. If the PNG was designed with GIF's limitations in mind (like flat icons or logos), conversion produces excellent results.

Can I convert GIF back to PNG?

Yes, using our GIF to PNG converter. However, converting back doesn't restore lost colors or smooth transparency from the original PNG. The round-trip preserves the GIF's limited palette and binary transparency—not the original PNG quality.

Is GIF or PNG better for website images?

PNG is better for most static images: more colors, smooth transparency, and often smaller file sizes for complex graphics. GIF's main advantage is animation. For best web performance, consider WebP which beats both formats in compression and quality.

Why do email clients sometimes require GIF format?

Some older email clients have limited image format support. GIF has been standard since 1987 and works in virtually all email software. While modern clients support PNG, GIF ensures maximum compatibility for email signatures and inline images.
