How this works in your browser
The conversion has two distinct steps, and each one throws something away. First the colour palette: GIF holds a table of at most 256 colours and stores each pixel as an index into it, so the encoder picks a representative palette and maps every pixel to the nearest entry. Second the transparency: PNG stores 256 levels of opacity per pixel, GIF stores one bit, so each pixel becomes either fully visible or fully invisible with nothing in between. That second step is what makes anti-aliased edges look jagged, since the soft blend PNG used to smooth a curve has no way to survive. The resulting indexed image is then LZW-compressed, which is efficient on flat colour and inefficient on detail.

How to use PNG to GIF
- 1
Open the PNG to GIF converter
Go to tools.slaytic.com and open the PNG to GIF tool. No sign-up or account required.
- 2
Drop your PNG file
Add the image. It is read directly from your device rather than uploaded.
- 3
Download the GIF
Save the static GIF, reduced to a 256-colour palette with binary transparency.
Frequently asked questions
What happens to transparency?
GIF supports only fully transparent or fully opaque pixels, no partial transparency, so any partially transparent edges in your PNG are rounded to one or the other.
Will colours look different?
For flat-colour graphics, usually not noticeably. For photos or gradients, GIF’s 256-colour limit can introduce visible banding.
Does this create an animated GIF?
No, this produces a single static frame from your still image.
Why do the edges of my logo look jagged now?
PNG anti-aliases edges using partial transparency, blending each edge pixel gradually into the background. GIF has no such thing, so every one of those pixels is forced to either fully visible or fully invisible. The smooth curve becomes a staircase. Designing with a hard edge in mind, or keeping the PNG where you can, avoids it.
Is GIF a good choice for a logo?
Only where it is required. For flat colour the palette limit costs you nothing, but PNG handles the same artwork with cleaner edges and genuine partial transparency. Convert to GIF when a platform demands it, not as an improvement.
Will the file be smaller than the PNG?
For simple flat-colour graphics, sometimes slightly. For anything detailed or photographic, usually not. Neither format is chosen for size in modern use, which is what WEBP and AVIF are for.
Is my image uploaded anywhere?
No. Quantisation and encoding both happen inside your browser tab.
