Why convert JPG to AVIF — the highest compression ratio for web images
Convert JPG to AVIF to achieve the highest compression efficiency available for web images today. AVIF is typically 50% smaller than JPG and 20% smaller than WebP at equivalent visual quality — not through heavier compression, but through a fundamentally more advanced codec. You can convert jpg to avif without losing quality: the output preserves all visible detail from the source JPEG. A 200 KB JPG photo becomes roughly 100–110 KB as AVIF, and a 500 KB product image might compress to 240–260 KB — all while looking identical to the original.
For websites where image weight is the primary bottleneck, the jpg to avif conversion offers the largest single improvement possible. A product page that previously served 15 JPEG images at 200 KB each (3 MB total) can serve the same images as AVIF at under 1.5 MB — a 50% reduction in image data per page load. This directly improves Largest Contentful Paint (LCP), a confirmed Google Core Web Vitals ranking factor. Google PageSpeed Insights will flag "serve images in next-gen formats" for any page still serving JPG when AVIF could be used instead.
AVIF browser support has reached approximately 90% of global traffic as of 2024. Chrome, Firefox, Safari (2023+) and Edge all support AVIF natively. For the remaining users on older browsers, serve AVIF with a WebP or JPG fallback using the HTML <picture> element — modern browsers load AVIF, older browsers fall back automatically. For jpg to avif online conversion aimed at internal tools or analytics-confirmed modern audiences, AVIF can be deployed without a fallback.
Using this avif converter is the best choice for advanced web optimization. For website use, AVIF delivers the best image size-to-quality ratio of any format — smaller than WebP, far smaller than JPG. For email or print workflows, keep JPG: email clients and print services do not support AVIF. For social media uploads, check platform support — most platforms transcode images on upload anyway, so format choice matters less. AVIF is the format of choice for jpg to avif for website optimization.
This jpg to avif online tool runs entirely in your browser. Your files never leave your device — no upload to any server, no third-party access, no data retention. Upload any number of JPG files, convert all in parallel and download as individual AVIF files or a ZIP archive. There is no account required, no file size limit and no daily conversion cap — completely free for any number of conversions.
You can also convert JPG to WebP for slightly broader browser compatibility, compress the JPG directly to stay in JPEG format, or convert AVIF back to JPG for universal compatibility.
- 1Upload your JPG files
Drag and drop one or more JPG or JPEG files onto the upload area, or click to browse. Upload any number of files — all processing runs locally in your browser with no upload to any server.
- 2Convert to AVIF
Click "Convert All" to process all files in parallel in your browser. Each JPG is decoded and re-encoded as AVIF using the browser's native AVIF encoder. The conversion targets equivalent visual quality to the source JPG while producing a significantly smaller file.
- 3Download your AVIF files
Each converted file shows the original JPG size and the output AVIF size so you can see the compression savings. Download AVIF files individually or click "Download All" for a ZIP archive. AVIF files are ready to upload to your website or CMS.
- 4Deploy AVIF on your site
Upload the AVIF files to your server and update image references. For maximum browser compatibility, use the HTML <picture> element: serve AVIF to browsers that support it and a WebP or JPG fallback for others. For modern-browser audiences, AVIF can be served directly.
Who converts JPG to AVIF — and why
Advanced web developers — maximum Core Web Vitals improvement
For developers already using WebP who want to go further, converting JPG to AVIF delivers the next level of image optimization. AVIF reduces image weight 20% beyond WebP — meaning a site already optimized with WebP can shave another 20% off its image payload by switching to AVIF. Implement AVIF with a WebP fallback via the <picture> element and serve the smallest possible image to every browser. Ideal for high-traffic sites where every kilobyte of page weight affects LCP scores and search rankings.
Ecommerce — smallest product images, fastest load times
Product pages are image-heavy: 20–50 images per page is common. Converting product JPG photos to AVIF reduces each image by up to 50%, cutting the total image payload for a product page from 4 MB to under 2 MB. This directly improves mobile page load times, reduces bounce rates and lowers server bandwidth costs at scale. Best practice: convert the full product image library to AVIF for website delivery, keep original JPGs for any email or print use cases.
Performance-focused content sites — future-proofing images
News sites, media platforms and content-heavy websites that serve large volumes of photographic content benefit enormously from AVIF. For a site publishing 50 articles per week, each with 5–10 photos, the accumulated bandwidth savings from jpg to avif conversion compound over time. AVIF's superior compression also means reduced CDN costs — at scale, the bandwidth reduction from AVIF versus JPG translates directly to lower infrastructure expenses.
Developers building image-optimized upload workflows
For web applications where users upload photos — portfolios, marketplaces, social platforms — converting uploaded JPGs to AVIF on the server (or in the browser before upload) reduces storage requirements by up to 50%. A user who uploads a 2 MB JPG photo produces a 1 MB AVIF that looks identical on screen. Over thousands of uploads, the storage savings are substantial. The best image format for web applications handling large volumes of user-uploaded images is AVIF, with fallback to WebP for older browser clients.

Maximum compression for web, privacy-first processing, and batch capability — built for cutting-edge image optimization workflows.
AVIF is 50% smaller than JPG and 20% smaller than WebP
AVIF (AV1 Image File Format) achieves the highest compression ratio of any widely-supported image format. At equivalent visual quality, AVIF files are typically 50% smaller than JPG and around 20% smaller than WebP. This means a 200 KB JPG photo becomes roughly 100 KB as AVIF — or even smaller. For websites with large image libraries, switching to AVIF delivers the biggest single reduction in page weight of any format choice available today.
Your image files never leave your device
All conversion runs locally in your browser using JavaScript and the Canvas API. No file is uploaded to any server, transmitted over the network or stored anywhere. The tool works without an internet connection after the initial page load. Safe for personal photos, product images under NDA and any content that cannot touch a third-party server.
Convert an entire image library to AVIF in one session
Upload as many JPG files as you need — there is no batch size limit. All files are processed in parallel in your browser. When all files are done, download them individually or use the "Download All" button to get a ZIP archive. Convert an entire product catalog, blog image library or marketing asset folder to AVIF in a single session.
AVIF on the web — complete guide
What is AVIF and why it's the best format for web images
AVIF stands for AV1 Image File Format. It was developed by the Alliance for Open Media — a consortium including Google, Apple, Mozilla, Netflix and Amazon — as a royalty-free, open-source image format built on top of the AV1 video codec. AVIF delivers the highest compression efficiency of any widely-supported image format. At the same visual quality, AVIF is typically 50% smaller than JPEG and around 20% smaller than WebP. For photographic content, this means a 300 KB JPEG photo can become 140–160 KB as AVIF with no visible quality difference. For a web page with 15 photos, switching from JPG to AVIF can save 2–3 MB of image data per page load. AVIF also supports a wider color gamut (HDR) and 10-bit or 12-bit color depth — well beyond what JPEG supports — making it future-proof for high-quality visual content. AVIF supports both lossy and lossless compression, and it supports alpha transparency (just like PNG and WebP), making it suitable for any type of web image.
AVIF vs WebP vs JPG — which format should you choose for web?
The right format depends on your target audience and performance requirements. JPG: mature, universally compatible, 97%+ browser support. Best when you need maximum compatibility or are delivering images outside the browser (email, print, desktop software). WebP: 25–35% smaller than JPG, 97%+ browser support (all modern browsers). The safe choice for web image optimization — excellent compression, broad support, and safer than AVIF for audiences with older browsers. AVIF: 50% smaller than JPG, 20% smaller than WebP, ~90% browser support as of 2024. The maximum-compression choice for cutting-edge web optimization. Chrome, Firefox, Safari (2023+), and Edge all support AVIF. For performance-critical sites targeting modern users — AVIF delivers the best results. The practical rule: if your audience is primarily modern browsers and performance is the top priority, convert JPG to AVIF. If you need a reliable safe choice with near-universal support, use WebP. Use the HTML <picture> element with a WebP fallback for AVIF to cover both bases.
AVIF browser support — is it safe to use?
AVIF browser support has grown rapidly. As of 2024, AVIF is supported by Chrome (since version 85, 2020), Firefox (since version 93, 2021), Safari (since version 16.4, 2023) and Edge (since version 121, 2024). Combined, these cover approximately 90% of global web traffic. For sites that must cover the remaining 10%, the recommended approach is to use the HTML <picture> element to serve AVIF to browsers that support it and WebP or JPG as a fallback. For example: <picture><source srcset="image.avif" type="image/avif"><source srcset="image.webp" type="image/webp"><img src="image.jpg" alt="description"></picture>. This approach delivers maximum compression to modern browsers while ensuring older browsers receive a compatible format. For internal tools, progressive web apps and sites where analytics confirm a modern browser audience, AVIF can be deployed directly without a fallback.

Upload your JPG file to this tool, click "Convert All" and download the AVIF output. The entire jpg to avif conversion runs in your browser — no upload, no account required. You can batch convert multiple JPG files at once and download all as a ZIP archive. The process takes a few seconds per image depending on your device.
Yes. Converting jpg to avif without losing quality is the primary goal of this tool. The AVIF output preserves the visual quality of the source JPG in a significantly smaller file. The WebP output will not be higher quality than the source — if the JPG already had compression artifacts, those are present in the output — but no new quality degradation is introduced by the conversion.
AVIF is typically 50% smaller than JPG at the same visual quality. A 200 KB JPG becomes roughly 100–110 KB as AVIF. The exact savings vary by image content — high-frequency detail images may see slightly less compression, while smooth photographic content can see savings above 50%.
For file size, yes — AVIF is approximately 20% smaller than WebP at the same quality. For browser support, WebP has slightly broader coverage (~97% vs ~90%). AVIF is the better choice when maximum compression is the priority and your audience uses modern browsers. WebP is the safer choice when broad compatibility matters more than squeezing out the last 20% of compression.
AVIF is the best image format for web in terms of compression efficiency. WebP is the best all-around choice balancing compression and compatibility. For performance-critical sites targeting modern browsers, AVIF with a WebP fallback is the optimal strategy. Both are dramatically better than serving JPG for website image optimization.
AVIF is supported by Chrome (2020+), Firefox (2021+), Safari (2023+) and Edge (2024+), covering approximately 90% of global web traffic. For the remaining users, serve AVIF with a WebP or JPG fallback using the HTML <picture> element.
