AVIF to WebP: what changes and when it makes sense

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.

WebP is a WebP format, developed by Google. It is best known for smaller files than JPG and PNG at similar quality, with transparency and animation in one format. The main drawbacks are rejection by some upload forms, older editors and email clients, and no wide-gamut or HDR support.

AVIF vs WebP at a glance

Property	AVIF	WebP
Type	Raster image	Raster image
Compression	Lossy or lossless, based on the AV1 video codec	Lossy (VP8) or lossless, chosen per file
Transparency	Full alpha channel with soft edges	Full alpha channel with soft edges
Animation	Yes	Yes
Colour depth	8, 10 or 12 bits per channel, with HDR and wide-gamut support	8 bits per channel
Support	Supported by current Chrome, Edge, Firefox and Safari, but many editors, social platforms and OS viewers cannot open it	Supported by current Chrome, Edge, Firefox, Safari and Opera, but not by every older editor, office suite or upload form
History	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).	Announced by Google in September 2010, based on the VP8 codec acquired with On2 Technologies. First format to combine lossy, lossless, alpha and animation in one specification. Safari support arrived in 2020 with macOS 11.

What actually changes in this conversion

AVIF can be lossy or lossless. A lossy source picks up a second round of compression when saved as WebP.
Transparency is preserved, including soft edges.
Expect the WebP file to be somewhat larger than the AVIF source.
Browser-based conversion works in 8-bit sRGB. Wide-gamut, 10-bit and 16-bit data are reduced. For colour-critical work, keep the original.
EXIF, GPS and camera data are stripped on every conversion. That is good for privacy, but you lose capture dates.

About AVIF: history and technical details

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).

About WebP: what you get

Announced by Google in September 2010, based on the VP8 codec acquired with On2 Technologies. First format to combine lossy, lossless, alpha and animation in one specification. Safari support arrived in 2020 with macOS 11.

Technical: Lossy WebP uses VP8 intra-frame coding with 4x4 and 16x16 block prediction. Lossless WebP uses a new algorithm with colour cache and LZ77 backward references. Max dimensions 16,383 by 16,383.

Real-world size: Lossy WebP at quality 80 is typically 25-35% smaller than JPG at quality 85 for photographs. Lossless WebP is 20-30% smaller than PNG for graphics. Google reports 80% savings on some assets after switching to WebP.

Popular tools: Google Chrome (built-in encoder), cwebp, Squoosh, ImageMagick, Adobe Photoshop 2020+, Figma, WordPress (via plugin).

Alternatives: AVIF (30-50% smaller but slower to encode), JPG (universally accepted), PNG (lossless), HEIC (Apple ecosystem).

Browser and software compatibility

AVIF: Supported by current Chrome, Edge, Firefox and Safari, but many editors, social platforms and OS viewers cannot open it. WebP: Supported by current Chrome, Edge, Firefox, Safari and Opera, but not by every older editor, office suite or upload form.

WebP is well supported by current browsers but still gets rejected by some editors and upload forms.

Why people move away from AVIF

Outside browsers, AVIF support is thin. Many editors, email clients and social platforms cannot open it.
Uploaders that accept only JPG or PNG reject AVIF files.
Fine texture such as film grain or fabric can look smoothed at aggressive AVIF settings.

Why people choose WebP

Lossy WebP is commonly 25 to 35 percent smaller than JPG at similar visual quality, which helps Core Web Vitals.
One format covers photographs, transparent graphics and short animations.
Lighthouse and other performance audits recommend modern formats like WebP.

Common mistakes with AVIF

Encoding AVIF at quality 90 thinking it will match JPG 90 — AVIF scale is different
Using AVIF for small icons — encoding overhead wastes savings
Expecting Photoshop (pre-2024) to open AVIF files — it will not

Best practices for keeping quality

AVIF files are often made for the web already. If you need to edit one, convert from the original source rather than stacking another lossy pass.
Quality 75-85 is a good default for photographs. Use lossless WebP for screenshots and interface graphics.
If you serve visitors on very old browsers, test there and keep a JPG or PNG fallback.
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.

AVIF to WebP questions

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

Why convert AVIF to WebP?

WebP files are typically smaller than AVIF, 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 AVIF to WebP lose quality?

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

Does WebP keep transparency?

Yes. WebP 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 WebP better than JPG?

For web delivery, yes. WebP is 25-35% smaller than JPG at similar visual quality and supports transparency and animation. JPG is still better for universal compatibility with older software.

Can WebP be animated?

Yes. Animated WebP is supported in all modern browsers and produces smaller files than animated GIF. It is one of three web formats supporting animation (GIF, WebP, AVIF).

Does WebP support transparency?

Yes. WebP supports full alpha transparency, including soft shadows and anti-aliased edges, in both lossy and lossless modes.

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.
