AVIF Converter Online

Batch Convert Multiple AVIF Images Online – Free & Private

Look, I've been there. You download a folder of AVIF images from a modern website, and then you try to open them in Photoshop, or attach them to an email, or upload them to some CMS, and they just... don't work. It's annoying, right? That's why I built this — a free AVIF converter that actually works without all the nonsense.

This tool lets you batch convert multiple AVIF images to JPG, PNG, WebP, GIF, BMP, TIFF, ICO, and PDF. You can adjust quality, resize images, and download everything as a single ZIP. No uploads, no watermarks, no signup — just pure, clean conversion right in your browser.

How to Batch Convert AVIF Images for Free

• Upload your AVIF files – Drag and drop your AVIF images into the upload area or click to browse.
• Choose your output format – Pick JPG, PNG, WebP, BMP, GIF, TIFF, ICO, or PDF.
• Adjust quality – Select Low, Medium, High, or Very High quality. High is the recommended default.
• Resize if needed – Keep original size, scale by percentage, use a preset, or enter custom dimensions.
• Click "Convert All" – The tool processes your files instantly in your browser.
• Download – Download each file individually or use the "Download All as ZIP" button.

That's it. No hidden steps. No "sign up to download" nonsense. Just convert and go.

Why Convert AVIF?

AVIF (AV1 Image File Format) is one of the most efficient web image formats available. It generally beats JPEG, PNG, and WebP on file size at the same perceptual quality. But here's the catch — AVIF is well supported in current browsers, but support outside the browser lags way behind. Older operating systems, many desktop image viewers, office apps, and pre-2023 versions of Photoshop don't read AVIF without an update or plugin.

Converting to JPG or PNG turns the file into something every program already understands. If your AVIF has transparency (like a logo or icon), convert to PNG to keep the alpha channel. For photos and full-frame images, JPG is the universal format that opens on every device. For documents or multi-image handouts, converting AVIF to PDF bundles the images into one file that opens anywhere.

Which Output Format Should You Choose?

Format	Best For	Transparency	Lossless
JPG	Photos, web images, email, printing	No	No
PNG	Logos, icons, graphics with transparency	Yes	Yes
WebP	Modern web, balanced size & quality	Yes	Yes
BMP	Windows apps, simple archiving	No	Yes
GIF	Simple animations, basic graphics	Limited	No
TIFF	Print, editing, archival workflows	Yes	Yes
ICO	Windows icons, favicons	Yes	No
PDF	Documents, multi-image sharing	Yes	No

Why I Made This (and Why You'll Actually Use It)

Here's the thing — I used to use those big online converter tools. They work, but they're slow, they have limits, and honestly, I never felt great about uploading my images to who-knows-where. So I built this. It's fast, it's private, and everything stays on your machine. No file size limits (well, browser memory is the limit, but that's usually plenty). No watermarks. No begging you to upgrade to "Pro."

I've used this to convert AVIF screenshots for presentations, convert AVIF logos to PNG for design work, and batch convert AVIF images to JPG for email attachments. It's one of those tools you don't think you need until you need it, and then you're really glad it exists.
