Convert WebP images to PNG format instantly in your browser. No upload, no account, completely free.
AVIF to JPG Converter
AVIF achieves the best compression ratios of any mainstream web image format but requires Chrome 85 or later, Firefox 93 or later, and Safari 16 or later for display. JPG is supported by every image viewer, email client, operating system, and application built since 1992. Converting AVIF to JPG trades compression efficiency for universal compatibility.
This converter processes your AVIF file locally in the browser using the Canvas API. No file is uploaded to any server at any point during conversion.
Where AVIF Compatibility Fails
Email clients are the most significant compatibility barrier for AVIF. Gmail, Outlook, Apple Mail, and virtually every corporate email client renders embedded images through a display engine separate from the system browser. Most email rendering engines do not decode AVIF. An AVIF embedded in HTML email will appear as a broken image in the majority of inboxes.
Desktop software built before 2022 — image editors, PDF creators, document management systems, and design tools — uses OS-level or application-level codec support that predates AVIF standardisation. AVIF files cannot be opened directly in these applications without a codec update. JPG opens natively in every environment without additional software.
Social platforms and e-commerce product image pipelines that were built before 2021 validate uploads against a codec allowlist that typically includes JPEG, PNG, WebP, and GIF. AVIF may be rejected at the upload boundary even on platforms whose delivery infrastructure now supports it.
AVIF vs JPG: Format Comparison
| Property | AVIF | JPG |
|---|---|---|
| Compression algorithm | AV1 intra-frame | DCT (Discrete Cosine Transform) |
| File size vs JPG at equivalent quality | 40 to 50% smaller | Baseline |
| Browser support | ~92% | Universal |
| Email client support | Minimal | Universal |
| OS-level viewer support | Limited without codec | Universal |
| Transparency | Yes | No |
| Standardised | 2020 | 1992 |
What the Conversion Preserves
The Canvas API decodes the AVIF image to raw pixel data, draws it to an offscreen canvas, and re-encodes it as JPEG. Transparency in the AVIF source is flattened to white, because JPEG does not support an alpha channel. If the original image contains a transparent background, the converted JPG will have a white background in those regions.
The quality slider controls the JPEG encoder’s compression level. A value of 85 to 92 produces output that is visually equivalent to the AVIF source for photographic content. The resulting JPG will be 40 to 50 percent larger than the AVIF because JPEG compression is less efficient than AV1.
How the Converter Works
Drop or select your AVIF file, adjust the quality slider if needed, then click Convert. The JPEG file downloads once processing completes. Processing runs entirely in the browser — nothing leaves your device.
