Convert AVIF to JPG
Turn AVIF images into universally-supported JPGs — in bulk, entirely on your own PC. No AV1 codec, no uploads.
TL;DR
Install the free trial, add your .avif files (or a whole folder), choose JPG, and convert. No AV1 Image Extension required — the converter decodes AVIF directly, and every file stays on your machine.
How to convert AVIF to JPG — step by step
Install LegacyFileConverter (free trial)
Get it from the Microsoft Store or download the offline MSI. The trial converts up to 25 files with every feature enabled.
Add your AVIF files or folders
Drag in individual .avif files, or point the app at a whole folder — it finds AVIF images recursively.
Choose JPG as the output
Select JPG for maximum compatibility. Prefer lossless or transparency? Convert to PNG instead — or do both in one run.
Convert offline
Click Convert. Files process locally in parallel and open in any image viewer, editor, or browser. Nothing is uploaded.
Why convert AVIF to JPG?
AVIF is a newer web image format that most Windows apps still can’t open — Photos needs the AV1 Image Extension, and older editors and viewers simply show a broken thumbnail. Converting to JPG gives you an image that opens and shares everywhere, on any device.
Because so few installed programs handle AVIF yet, a batch converter is often the only practical way to deal with a folder of them. JPG is the safe, universal target for photos and web images alike.
Safer than online AVIF converters
Searching for a "free online AVIF to JPG converter" means uploading your files to someone else's server — a real problem for confidential documents, personal photos, and any private archive. LegacyFileConverter runs entirely on your Windows PC: files are converted locally and never leave your machine. It also handles whole folders in one batch, which no upload-one-file-at-a-time website can do.
The free trial converts up to 25 files with every feature enabled — for most people that's the whole job. Larger archives are covered by a one-time $99 lifetime license. No subscription, no watermarks, no uploads.
Frequently asked questions
Is there a free way to convert AVIF to JPG?
Yes. The free trial of LegacyFileConverter converts up to 25 files with full features — no signup, no watermarks. For unlimited conversions, a lifetime license is a one-time $99 (no subscription).
Is this an online converter? Do my files get uploaded?
No. LegacyFileConverter is a Windows desktop app — every conversion runs 100% locally on your PC. Nothing is uploaded, which matters for confidential documents and personal files that shouldn't be pasted into a random website.
Can I convert a whole folder of AVIF files at once?
Yes. Point LegacyFileConverter at a folder (it scans subfolders recursively), select JPG as the output, and it batch-converts every .avif file in one run.
Can this app convert more than just this one format?
Yes — that's the point. LegacyFileConverter handles 100+ legacy and modern formats in a single app: WordPerfect, Lotus 1-2-3, Quattro Pro, Microsoft Works, XPS, HEIC, Photoshop (PSD), TIFF, AVIF, and many more. One tool covers your whole mixed archive.
Do I need the AV1 Image Extension from the Microsoft Store?
No. This app decodes AVIF on its own, so you don’t need the paid/optional AV1 Image Extension that Windows Photos relies on.
Will I lose image quality converting AVIF to JPG?
JPG is lossy, so there’s a small quality trade-off like any JPG. For pixel-perfect results with transparency, convert AVIF to PNG instead.
