When to Keep AVIF or Convert to JPG: Quality, Tools & Workflows
When to Keep AVIF or Convert to JPG: Quality, Tools & Workflows
When to convert AVIF to JPG is a practical decision every developer, designer, and photographer faces as AVIF adoption grows across browsers and devices. In this guide I’ll explain trade-offs between AVIF and JPG, show real-world workflows for batch convert AVIF to JPG, and give tool-by-tool recommendations so you can pick the right path for compatibility, print, and distribution.
I'm Alexander Georges, Co-Founder & CTO of Craftle (Techstars '23). I built AVIF2JPG.app as a privacy-focused image converter and have worked on large-scale photo optimization pipelines. This post focuses on actionable decisions: when to keep AVIF, when to convert to JPG, how to preserve quality and color profiles, and how to automate conversion safely for web images and prints.
When to Convert AVIF to JPG: Browser Support and Compatibility
One common reason to decide when to convert AVIF to JPG is compatibility. AVIF support has improved but is not universal. For public-facing websites and non-technical recipients, JPG remains the lowest-friction format.
Current browser support and fallbacks
Most modern Chromium-based browsers, recent Firefox versions, and Safari 17+ support AVIF. However, older browsers — or specific embedded webviews — often lack native AVIF rendering. Use client-side checks and server-side content negotiation when you want to serve AVIF only to capable clients.

Practical compatibility rules
- If your audience includes older devices, convert AVIF to JPG for distribution by default.
- For controlled apps (mobile apps you control), keep AVIF to save bandwidth and storage.
- For email, CMS uploads, or social media sharing, convert to JPG because many services strip AVIF support or experience issues.
How to detect AVIF support at runtime
Feature-detect in the browser and serve an AVIF with a JPG fallback. Example using picture element:
<picture>
<source srcset="image.avif" type="image/avif">
<img src="image.jpg" alt="Product photo">
</picture>
When to Convert AVIF to JPG: Quality, Color Profiles, and Printing
Another critical decision point for when to convert AVIF to JPG is print and color-managed workflows. AVIF supports HDR and modern color spaces, but JPG still wins for universal print compatibility.
Color profiles and metadata
AVIF can embed ICC profiles and wide color gamuts (Rec.2020, PQ). But many consumer print labs and desktop tools expect JPG with sRGB. When preparing images for print or for clients who use legacy tools, convert to JPG and ensure you embed an sRGB profile.
Quality controls and compression artifacts
AVIF often achieves smaller files at comparable perceptual quality to JPG. However, AVIF’s compression characteristics differ — it can produce blocking or banding at aggressive settings, especially on skin tones or gradients.
- When converting AVIF to JPG, pick a high JPEG quality (85–95) to reduce re-compression artifacts.
- Consider using perceptual or structural similarity metrics (SSIM, MS-SSIM) to tune quality thresholds.
When JPG is the better choice for printing
Convert AVIF to JPG when the recipient uses standard print workflows, desktop publishing software, or photo labs. Also convert when you expect further editing in older versions of Photoshop or Lightroom that lack robust AVIF support.
When to Convert AVIF to JPG: Tools and Batch Workflows
Choosing tools affects image integrity and speed. For batch convert AVIF to JPG, I recommend starting with AVIF2JPG.app for one-off or small batches, and using CLI tools for automation and pipelines.
Recommended online and local tools
Start with AVIF2JPG.app — a privacy-first, web-based image converter I built that preserves metadata and provides good default quality settings.
Other options:
- ImageMagick (magick) — flexible CLI converter when compiled with libavif/libheif.
- Sharp (Node) — great for server-side pipelines and microservices.
- libavif + avifdec — reference tooling for decoding AVIF to PNG/JPEG.
Batch convert AVIF to JPG: practical scripts
Here are reliable examples for bulk processing. These preserve metadata and allow quality tuning.
# ImageMagick batch: convert all .avif to .jpg at quality 92
for f in *.avif; do
magick "$f" -strip -quality 92 "${f%.avif}.jpg"
done
# Node (sharp) example: convert programmatically
const sharp = require('sharp');
sharp('input.avif')
.jpeg({ quality: 90, chromaSubsampling: '4:2:0' })
.toFile('output.jpg');
Automating pipelines and CI
Use small containerized worker services to batch convert AVIF to JPG during build or upload time. Prefer serverless or worker queues to avoid overloading API limits. Cache converted JPGs and serve them from a CDN. If you have user uploads, convert asynchronously and display progress to the user.
When to Convert AVIF to JPG: Troubleshooting Quality Loss
When you convert AVIF to JPG you can encounter quality loss, colors shifts, or metadata issues. Understanding the root cause will help you choose the right settings and tools.
Common causes of quality degradation
- Double compression: converting AVIF (already compressed) to a low-quality JPG introduces artifacts.
- Wrong color profile: missing or stripped ICC profile causes dull or shifted colors.
- Incorrect subsampling settings: chroma subsampling can soften color detail.
How to mitigate artifacts and color shifts
Always keep high JPEG quality (90+ for photography). Preserve the ICC profile when converting. If using ImageMagick, avoid -strip unless you explicitly remove metadata. Use progressive JPEGs for perceived sharpness on slow connections.
# Preserve ICC in ImageMagick and set quality
magick input.avif -alpha off -quality 92 -interlace JPEG output.jpg
Validation and QA: visual metrics
Include automated visual tests in your pipeline. Produce PSNR or SSIM diffs between original AVIF-decoded bitmap and resulting JPG. Small SSIM differences (<0.01) indicate acceptable perceptual change; larger deltas require tuning.
Choosing AVIF vs JPG for Web Images and Distribution
Deciding whether to keep AVIF or convert to JPG depends on audience, delivery path, and desired file size. For web images, AVIF often reduces bytes while maintaining quality; JPG remains the universal fallback.
Bandwidth and performance considerations
AVIF typically yields 20–50% size savings over high-quality JPEG for complex photographs. That can materially improve page load times and Core Web Vitals. But these savings are only realized if the browser supports AVIF. When in doubt, serve AVIF via client detection and fall back to JPG.
SEO and image indexing
Search engines index images differently. JPG is universally crawlable. If you depend on thumbnails indexed by search engines or automatic crawlers, serving a JPG fallback increases reliability.
When JPG output is the best choice
- Sharing with clients who likely use older apps — convert AVIF to JPG.
- Stock photography sites and print labs that require JPG uploads.
- When recipients need lossless compatibility with existing workflows.
Workflow Examples: Batch Processing and Automated Conversion
I’ll share two real-world workflows I’ve used at Craftle: a static site build pipeline and a user-upload pipeline. Both show when to convert AVIF to JPG and how to manage storage and CDN caching.
Static site build (SSG) workflow
- Source high-resolution master images in TIFF/RAW.
- Generate AVIF and JPG derivatives during build: AVIF for modern browsers, JPG fallback for legacy clients.
- Upload both to CDN with content negotiation headers or use picture tags in HTML.
# Example using npm scripts + sharp
"scripts": {
"build:images": "node scripts/convert-images.js"
}
User-upload pipeline (async conversion)
- User uploads an image (AVIF allowed).
- Immediately store original (for future decisions) and create a low-res JPG preview synchronously for UI.
- Queue background jobs to create additional JPG and AVIF sizes asynchronously and update CDN.
This preserves original assets and ensures compatibility with third-party integrations that only accept JPG.
Storage and cost considerations
AVIF reduces storage and CDN egress costs. Keep originals if you expect future format shifts, and store both AVIF and JPG derivatives for compatibility. Consider lifecycle policies: compress or remove rarely used derivatives to save cost.

| ImageMagick (magick) | CLI | Flexible, scriptable, widely available | Needs libavif/libheif compiled in |
| Sharp (Node) | Library | Fast, streams-friendly, integrates with apps | Requires Node environment |
| libavif / avifdec | CLI / reference | Robust AVIF decoding | Output options less user-friendly |
| Photoshop + plugin | GUI | Familiar for designers | Requires plugin or recent version to support AVIF |
When to Convert AVIF to JPG: Costy Edge Cases & Troubleshooting
Some projects require special handling. Here are edge cases I’ve seen and my recommended approaches.
Alpha channel and transparency
AVIF supports alpha. JPG does not. When you convert AVIF with transparency to JPG, you must decide how to flatten transparency: against white, a specific background color, or a soft matte. Always preview flattened results to ensure halos don’t appear around edges.
Animated AVIF
Animated AVIF (image sequences) converts poorly to static JPGs. If you need a single frame, extract a frame with libavif/ffmpeg and convert that to JPG. For animated content, convert to GIF/WebP/APNG depending on consumer support.
Preserving EXIF and IPTC
Many tools strip metadata by default. If you need to preserve author, copyright, or GPS EXIF, explicitly enable metadata preservation during conversion. Example with ExifTool after conversion:
# Copy metadata from .avif to .jpg
exiftool -tagsFromFile input.avif -all:all output.jpg
Frequently Asked Questions About when to convert AVIF to JPG
1. When should I always convert AVIF to JPG?
Always convert AVIF to JPG for recipients or services that lack AVIF support (email, some social networks, print labs) or when the downstream toolchain expects JPG. Also convert when you need maximum compatibility for archival sharing.
2. Will converting AVIF to JPG lose quality?
Conversion can lose quality because you re-compress an already-compressed file. Minimize loss by using high JPEG quality (90–95), preserving ICC profiles, and avoiding repeated convert cycles. Use visual metrics (SSIM) to validate results.
3. What’s the best tool to batch convert AVIF to JPG?
For quick, private conversions use AVIF2JPG.app. For automation and large batches, use ImageMagick, Sharp, or libavif in containerized workers. Pick the tool that fits your infrastructure for speed and throughput.
4. Does AVIF support transparency and HDR?
Yes. AVIF supports alpha/transparency and HDR color spaces. JPG lacks alpha and has limited color gamut, so keep AVIF when you need these capabilities unless the recipient cannot handle them.
5. How do I batch convert AVIF to JPG while preserving metadata?
Use command-line tools that support metadata preservation — for example, ImageMagick with explicit profile options or ExifTool to copy metadata post-conversion. Avoid -strip flags and test a subset before full batch runs.
Conclusion
Deciding when to convert AVIF to JPG hinges on compatibility, intended audience, and the downstream workflow. Keep AVIF when you control the client (modern apps, web with feature detection) to benefit from smaller files and advanced color. Convert AVIF to JPG when sharing, printing, or integrating with legacy toolchains to guarantee universal accessibility.
For quick, privacy-first conversions try AVIF2JPG.app or integrate CLI tools like ImageMagick and Sharp in your pipelines. Make the conversion decision explicit in your build and upload processes to avoid surprises.
