GIF to AVIF: what changes and when it makes sense

GIF is a Graphics Interchange Format. It is best known for simple animation that plays everywhere without a video player. The main drawbacks are a 256-colour limit and on-or-off transparency, which cause banding in photos and jagged edges.

AVIF is an AV1 Image File Format. It is best known for the smallest files of any common web format at a given quality. The main drawbacks are slow encoding, patchy support outside browsers, and smoothing in fine textures at aggressive settings.

GIF vs AVIF at a glance

Property	GIF	AVIF
Type	Raster image	Raster image
Compression	Lossless LZW compression, after reducing each frame to a 256-colour palette	Lossy or lossless, based on the AV1 video codec
Transparency	On or off only, no soft edges	Full alpha channel with soft edges
Animation	Yes	Yes
Colour depth	8-bit indexed colour, 256 colours at most	8, 10 or 12 bits per channel, with HDR and wide-gamut support
Support	Plays and displays everywhere, including email clients and chat apps	Supported by current Chrome, Edge, Firefox and Safari, but many editors, social platforms and OS viewers cannot open it
History	Developed by CompuServe in 1987 (GIF87a) and updated to GIF89a in 1989, adding animation and transparency. The LZW compression patent held by Unisys caused a crisis in the 1990s and motivated the creation of PNG. GIF usage is still massive despite being technically obsolete.	Finalised in 2019 by the Alliance for Open Media (Google, Mozilla, Apple, Microsoft, Netflix, Amazon, Intel and others). Based on AV1 video codec, successor to VP9 and HEVC. First major browser support: Chrome 85 (2020).

What actually changes in this conversion

A GIF has only 256 colours, so the AVIF file inherits its banding.
Expect the AVIF file to be far smaller than the GIF source.
EXIF, GPS and camera data are stripped on every conversion. That is good for privacy, but you lose capture dates.

About GIF: history and technical details

Developed by CompuServe in 1987 (GIF87a) and updated to GIF89a in 1989, adding animation and transparency. The LZW compression patent held by Unisys caused a crisis in the 1990s and motivated the creation of PNG. GIF usage is still massive despite being technically obsolete.

Technical: Up to 256 colours per frame from a palette. LZW compression on the indexed pixel data. Supports transparency (one palette index is transparent). Animation via multiple frames with per-frame delays. No true 24-bit colour.

Real-world size: A 500-frame animated GIF at 800x600 is 15-30 MB. The same animation as MP4 is 1-3 MB (90% smaller). A single 800x600 GIF frame is 100-500 KB; as PNG it is 200-600 KB but with better colour.

Popular tools: Photoshop, GIMP, ScreenToGif, Gifski, ImageMagick, FFmpeg, Ezgif.

Alternatives: MP4 (90% smaller for animation), WebP (animation with 16M colours), APNG (rarely used), PNG (for static frames).

About AVIF: what you get

Finalised in 2019 by the Alliance for Open Media (Google, Mozilla, Apple, Microsoft, Netflix, Amazon, Intel and others). Based on AV1 video codec, successor to VP9 and HEVC. First major browser support: Chrome 85 (2020).

Technical: AV1 intra-frame coding with variable block sizes from 4x4 to 128x128. Supports 8/10/12-bit colour, HDR, wide gamut (BT.2020), monochrome. HEIF-based container. Encoding is 10-100x slower than JPEG.

Real-world size: AVIF at quality 50 produces files 30-50% smaller than JPG at quality 85 with similar visual quality. Netflix reports 50% bandwidth savings after switching. Google reports AVIF is 20-30% smaller than WebP.

Popular tools: Adobe Photoshop 2024+, GIMP 2.10+, Squoosh, avifenc, ImageMagick, AVIF.io, Netflix (production use).

Alternatives: WebP (faster encode, less compression), JPG (universal), HEIC (Apple-only), JPEG XL (future format).

Browser and software compatibility

GIF: Plays and displays everywhere, including email clients and chat apps. AVIF: Supported by current Chrome, Edge, Firefox and Safari, but many editors, social platforms and OS viewers cannot open it.

AVIF is well supported by current browsers but is still rejected by many editors and social platforms.

Why people move away from GIF

A palette of 256 colours cannot reproduce photographs or smooth gradients, and transparency is on or off with no soft edges.
Animated GIFs are heavy compared with MP4 or WebM video, which can be a fraction of the size for the same clip.

Why people choose AVIF

AVIF often produces files 30 to 50 percent smaller than JPG at comparable quality.
It can carry 10-bit and HDR content that JPG and WebP cannot.
It pays off most on hero images and large photo galleries, where bytes matter the most.

Common mistakes with GIF

Using GIF for photos — banding and dithering ruin the image
Not compressing animated GIFs — they can be 10-20x larger than equivalent MP4
Expecting GIF to have smooth transparency — it is on or off only

Best practices for keeping quality

A canvas-based still conversion draws a single frame, normally the first. Extract or trim the frame you want before converting an animated GIF.
AVIF quality numbers do not line up with JPG. Start around 60-70 and compare against the original at 100 percent zoom.
Serve AVIF with a WebP or JPG fallback using the picture element so older browsers still get an image.
Resize before converting if the image will be shown small. A 4000 pixel photo displayed at 800 pixels wastes bytes in any format.
Check the result at 100 percent zoom, especially around text, edges and gradients, before you replace any originals.
Keep your original files. Conversions to a lossy format cannot be undone.
When you convert a set of images, use the same quality setting for the whole batch. The converter handles up to 20 files at once.

GIF to AVIF questions

Quick answers about privacy, quality, supported formats, file limits and how AVIF works.

Why convert GIF to AVIF?

AVIF files are typically smaller than GIF, which makes them faster to share, send and load. The trade-off is a small amount of image detail at low quality settings.

Will converting GIF to AVIF lose quality?

At 90% quality, most people cannot tell the difference. Use 85-95% for photos and you are fine.

Does AVIF keep transparency?

Yes. AVIF supports full transparency, so transparent areas in your original are kept.

Are my files uploaded?

Never. Everything runs in your browser. Your files never leave your device. Open DevTools Network tab while processing — you will see no upload request.

Can I convert many files at once?

Yes, up to 20 files at once. Download them individually or all together as a ZIP.

Does the converter strip metadata?

Yes. Browsers do not pass EXIF data through a canvas, so GPS, camera model and dates are removed on every conversion. That is good for privacy.

Is it free?

Yes. No credits, no daily cap, no account, no watermark. The practical limit is your device memory.

Is AVIF smaller than WebP?

Yes, typically 20-30% smaller at similar quality. But AVIF is much slower to encode and has less software support outside browsers.

Does AVIF support HDR?

Yes. AVIF supports 10-bit and 12-bit colour, HDR (Hybrid Log-Gamma and PQ), and wide-gamut BT.2020 colour. JPG and WebP cannot do this.

Can AVIF be animated?

Yes, though animated AVIF support is still limited in browsers. Chrome and Firefox support it, Safari does not as of early 2026.

Your files never leave your device

No upload, no account, no tracking. Everything happens in your browser using the Canvas API and WebAssembly. You can confirm this in your browser's DevTools Network tab while the tool runs — no request carries your file. See why ToolDeck is different.
