Convert Images in 4 Simple Steps
Quickly transform your images with our streamlined conversion process. Every file is processed through a scalable background queue with real-time status updates — so you can convert hundreds of images at once and watch each one move from In queue to Processing to Ready. No software installation required.
Upload Image Files
Click 'Choose Files' or drag & drop your images into the upload area. Supports multiple files at once.
Select Format & Settings
Choose your target format (WebP, PNG, JPG, etc.) and adjust quality, size, and other conversion options.
Queued & Converted
Click 'Convert All' and each image is queued and processed in the background. Track live status for every file — In queue, Processing, then Finalizing — updated in real time.
Download
As soon as a file is Ready, download it individually or grab everything as a ZIP. Queued processing keeps large batches going even with hundreds of images.
How the Image Converter Works
Drop your images, pick a target format, and convert. Every file is queued and processed in the background with real-time status — In queue, Processing, then Ready — so you can convert hundreds of images at once without the page freezing.
From WebP to AVIF: Squeezing Out More Compression
WebP has been the web's efficient-image workhorse since 2010, cutting file sizes 25-35% versus JPEG with broad browser support. AVIF, standardized in 2019 on top of the AV1 video codec, pushes further — often another 20-30% smaller than WebP at comparable quality, plus support for HDR and wider color gamuts that WebP lacks.
Why Convert WebP to AVIF?
If your website is already using WebP for performance and you're chasing every last bit of Core Web Vitals improvement, AVIF is the next step up. It's especially worthwhile for image-heavy pages — galleries, product listings, hero banners — where every kilobyte saved compounds across many images.
What to Check Before Switching
AVIF's browser support (90%+, including Safari 16+) is now strong but slightly behind WebP's near-universal coverage, and AVIF encoding takes longer. For most modern websites the tradeoff is worth it; if you need guaranteed support on very old browsers, keep a WebP fallback.
Why Convert WebP to AVIF Online
Even Smaller Files
AVIF typically compresses 20-30% smaller than WebP at the same visual quality.
HDR & Wide Color Gamut
AVIF supports high dynamic range and wider color, which WebP doesn't offer.
Better Core Web Vitals
Smaller image payloads improve Largest Contentful Paint and overall page speed scores.
Batch Conversion
Convert your entire WebP image library to AVIF in one upload.

Where WebP and AVIF Each Make the Most Sense
Broad-Audience Web Delivery
WebP's 95%+ browser support makes it the safest choice when you need maximum compatibility without fallbacks.
Legacy Device & Older Browser Support
If your audience includes older phones, tablets, or enterprise browsers, WebP's wider compatibility ensures everyone sees the image.
Optimizing Images for High-Traffic Blogs & Photo Galleries
AVIF's aggressive compression keeps hero images and photo galleries light, which is exactly what you need when you optimize images for a fast-loading website.
High-Volume Ecommerce Product Photos
Sites serving thousands of product images benefit most from AVIF's file-size savings, since the reduction compounds across every image displayed.
Modern Photography Portfolios & Portfolio Websites
Professional photographers showing cutting-edge work can adopt AVIF to get 20-30% more compression than WebP while impressing tech-savvy visitors with next-generation formats.
