Why use this WebP to AVIF?

Convert WebP to AVIF online with secure cloud processing. Create a smaller modern image with adjustable quality and transparency support. Free to start.

Squeezes out extra savings

AVIF's AV1 codec often compresses 10–40% smaller than WebP at similar visual quality, useful when every kilobyte counts.

Optimized encoding pipeline

Re-encoding to AV1 takes more CPU work than WebP's own codec, but our pipeline is tuned to keep the process efficient rather than instant.

Broad — but not universal — support

AVIF displays in all modern browsers, though some older apps and tools can't open it yet, worth checking before you standardize on it.

Secure processing, auto-deleted

Files travel over encrypted HTTPS and are processed on our servers; converted AVIFs are deleted within 24 hours and original uploads within 6–24 hours.

How to use the WebP to AVIF

  1. 01

    Upload your WebP

    Drag and drop or select a WebP image. Anonymous visitors can upload up to 20 MB; free accounts get 50 MB and 3 conversions every 30 days; paid plans allow 200 MB and batches of up to 100 files.

  2. 02

    Set your AVIF quality

    Choose a quality from 1–100 — around 65–80 is recommended since the source WebP is usually already lossy, and going too low compounds the loss.

  3. 03

    Server re-encodes with AV1

    Our servers decode the WebP and re-encode it with AV1, which typically compresses further than WebP's own codec. This CPU-intensive step runs through an optimized pipeline rather than finishing instantly.

  4. 04

    Download your AVIF

    Grab your AVIF from a secure signed link — often 10–40% smaller than the WebP at similar quality. The output file is deleted automatically within 24 hours.

About the formats

WebP

WebP is a modern image format developed by Google that supports both lossy and lossless compression, along with transparency and animation. At comparable visual quality it usually produces noticeably smaller files than JPG or PNG.

Every current browser supports WebP, which makes it an excellent default for web delivery. Outside the browser the picture is mixed: older desktop software, some email clients, and legacy systems may fail to open it. If a recipient cannot view a WebP file, convert it to JPG for photos or to PNG when transparency must be preserved.

AVIF

AVIF is a modern, royalty-free image format based on the AV1 video codec, developed by the Alliance for Open Media. It is one of the most efficient web image formats available today.

AVIF combines excellent compression with alpha transparency, HDR, and wide color gamut support, and typically beats both JPG and WebP in file size at equal quality. Encoding is noticeably slower than other formats, and viewing requires a modern browser — older systems and many desktop apps cannot open it. Keep a JPG or WebP fallback when your audience may include legacy environments.

WebP to AVIF troubleshooting

My WebP won't upload
Check that the file has a .webp extension and really is a WebP — files saved from websites are sometimes renamed JPGs or PNGs. Also confirm it is within your size limit (20 MB anonymous, 50 MB free, 200 MB paid).
The AVIF looks softer than the WebP
That is generation loss from re-encoding a lossy source. Raise the quality setting to 75 or higher; if the WebP itself was heavily compressed, the AVIF cannot restore detail that was already gone.
The file barely got smaller
If the WebP was already compressed aggressively, or the image is small, AVIF has little left to squeeze. Savings are biggest on large, moderately compressed images.

FAQ

Why convert WebP to AVIF?
AVIF's AV1 codec usually compresses better than WebP, so the same image can be 10–40% smaller at similar quality — useful for web performance budgets and Core Web Vitals.
Does re-encoding lose quality?
Both WebP and AVIF are typically lossy, so re-encoding can lose a little detail each generation. Keep the quality setting moderate to high and, when possible, convert from the highest-quality WebP you have.
Can I batch convert multiple WebP files to AVIF?
Yes, with an account. Free accounts can batch up to 5 files at a time, and paid plans support batches of up to 100 files. Anonymous visitors can convert one file per session.
How long does converting WebP to AVIF take?
Longer than a simple format swap. AV1 encoding is more CPU-intensive than WebP's own codec, so this tool runs the image through an optimized encoding pipeline rather than finishing instantly. Most single images still convert within seconds; large batches take proportionally longer.
Will the AVIF always end up smaller than the WebP?
In most cases, yes, but not guaranteed. If the WebP was already compressed aggressively or the image is small and simple, AVIF may only save a little — the biggest gains show up on larger, moderately compressed images.
Are my files private?
Yes. Files are uploaded over an encrypted HTTPS connection and processed on our servers. Converted outputs are deleted automatically within 24 hours, and your original uploads are removed within 6–24 hours. We never share your images.
What are the size and usage limits?
Anonymous visitors can upload files up to 20 MB and get 1 free server conversion. A free account raises this to 50 MB per file, 3 free conversions every 30 days, and batches of up to 5 files. Paid plans allow 200 MB per file and batches of up to 100 files.
