Still images only. FLIF: 8 MiB, 8-bit samples. Other images: 20 MiB. 1 million pixels and 2,048 pixels per edge.

Export formatJPEG / WebP quality

Open a file or try the example.

Preview

FLIF export is decoded again and checked for exact visible RGB and alpha. Hidden RGB under zero alpha may change. Canvas decoding can normalize transparent RGB and color profiles before export. Metadata and animation are not retained. FLIF is a legacy format; use PNG for broad compatibility.

Using FLIF Image Converter

Read supported still 8-bit FLIF files or create verified lossless FLIF from decoded image pixels.

Open a supported FLIF, PNG, JPG or WebP, or try the example.
Choose FLIF for verified RGBA8 lossless encoding, or a common image format.
Download the converted image.

Example

Try the transparency example, export FLIF and reopen it to compare pixels.

Questions & answers

What does lossless mean here?

Still exports verify visible RGB and alpha after decoding. Hidden RGB beneath fully transparent pixels can change. Animation preserves decoded 8-bit frames and chosen timing; original metadata and profiles are omitted.

Will FLIF open in normal browsers?

Generally no. PNG is the more compatible sharing format.

Can I convert animated FLIF?

The animation panel creates FLIF from up to 20 same-size PNG frames or extracts supported 8-bit FLIF frames to PNG ZIP with a timing manifest. Up to 8 million total frame pixels. Higher precision, metadata and original loop settings are omitted.
