A Developer's Guide to Converting AVIF to JPG

Q: Which conversion method should I use?

The best method depends on your specific task. Use an online tool for quick single file or small batch conversions. Use a bulk online converter for converting folders of images without scripting. Use command-line tools like ImageMagick or FFmpeg for automation, integration, and precise control over quality settings.

Q: What JPG quality setting should I use for web images?

For most web images, a quality setting between 80-85 provides an excellent balance between visual quality and file size. At this range, compression artifacts are minimal and typically imperceptible. Use higher settings (90+) only for hero images where quality is paramount. Lower settings (70-79) can work for thumbnails or situations where smaller file size matters more than fine detail.

Why JPG is Still Relevant in an AVIF World

AVIF improves web performance with an advanced compression algorithm. It creates smaller files than JPG at a similar visual quality. Smaller files lead to faster page loads and reduced bandwidth usage, which benefits user experience and SEO.

However, many business tools and older platforms do not support AVIF. A reliable AVIF to JPG conversion process is a practical requirement for interoperability.

The core trade-off: When you convert AVIF to JPG, you are choosing compatibility over file size efficiency. For tasks like sending images in marketing emails or uploading to a legacy CRM, JPG is the dependable format.

The size difference is notable. An AVIF file is often 30-50% smaller than a JPG of comparable quality. This means converting to JPG will always produce a larger file. You can explore the benefits of the JPG format in more detail.

AVIF vs. JPG Comparison

Feature	AVIF	JPG
Compression	Superior lossy compression, smaller files	Good lossy compression, less efficient
Compatibility	Growing support, not yet universal	Near-universal support across all devices
File Size	Typically 30-50% smaller for similar quality	Larger than AVIF for the same quality
Ideal Use Case	Modern websites and web applications	Email, social media, legacy systems, print

Common Scenarios Requiring JPG Conversion

You will encounter many situations that require a JPG, even with a high-quality AVIF source file:

When you need JPG instead of AVIF

Email Marketing — Most email clients lack support for modern image formats. Sending a JPG ensures it displays correctly for all recipients.
Social Media Platforms — Some platforms prefer or require JPG uploads to maintain consistency for their user base.
Third-Party Integrations — Systems like inventory management software or partner portals often have strict format requirements, with JPG being the standard.
Print and Desktop Publishing — The print industry workflows are built around formats like TIFF and JPG. AVIF is not part of this established process.

Quick Conversions with Online Tools

For converting a single AVIF file or a small batch, an online tool is the fastest method. It is a practical solution for one-off tasks without installing new software.

The process is typically straightforward: upload the AVIF, select JPG as the output, and download. Before using any service, it is wise to review its privacy and security practices.

How to Identify a Trustworthy Converter

A reliable online tool is transparent about its security features. Look for clear indicators that they respect your privacy and protect your files:

Key security features to look for

Encryption — The connection should use TLS 1.3 encryption. This protects data in transit between your computer and their servers.
Clear Data Policies — The service should state where files are processed. EU-based servers are a good signal, as they must comply with GDPR.
Automatic Deletion — The service must specify how long it retains your files. A policy of permanent deletion within one hour of conversion is a strong privacy feature.

When a tool clearly states its data handling practices, it signals a serious commitment to user privacy. This information is often available directly on the upload page.

The Conversion Process

Using an online tool should be fast and efficient. For example, a marketer needing to convert an AVIF image for an email platform would follow these steps:

Steps to convert AVIF to JPG online

Navigate to a privacy-focused converter like Convert.FAST.
Upload the AVIF file by dragging and dropping or clicking to browse.
The conversion to JPG begins automatically.
Download the new JPG file when processing completes.

This method is efficient for small jobs, often taking less than a minute. Its main limitation is that it is not designed for processing hundreds or thousands of images at once without automation.

Handling Bulk Conversions in Production

When dealing with hundreds or thousands of files, manual conversion is not practical. This is a common scenario for development and operations teams. Automating this process is a necessity, not a luxury.

A programmatic approach to AVIF to JPG conversion makes the process fast, reliable, and integrable into existing workflows.

Scaling with Batch Processing

Dedicated services designed for high-volume conversions are ideal for this task. These systems use parallel processing to convert many files simultaneously, significantly reducing wait times.

Batch processing capabilities

A robust system can handle up to 1,000 files per job. This allows you to process entire product categories in a single automated step.

You can learn more about how batch processing works and its integration capabilities.

The cost-benefit is clear when you consider the labor involved. A marketing team might need 5-10 JPG versions for each product, potentially leading to hundreds of thousands of conversions per year. A centralized service reduces this workload significantly.

Real-World Production Scenarios

Bulk AVIF to JPG conversion solves tangible business problems. It bridges modern image formats with legacy system requirements:

Production use cases

E-commerce Syndication — A primary website can serve lightweight AVIF files while an automated job converts them to JPGs for partner feeds like Google Shopping.
Digital Asset Management — A DAM can store master assets as AVIF for quality and compression. A self-service portal can then convert these to JPG on-demand for sales or marketing use.
CI/CD Pipelines — A script can automatically generate JPG fallbacks from AVIF source images during deployment. This ensures the application ships with compatible assets for all environments.

Automating Conversions with Command-Line Tools

For developers, the most efficient way to handle AVIF to JPG conversions is through automation. Command-line interface (CLI) tools are scriptable, predictable, and offer fine-grained control.

This approach is well-suited for any automated workflow. Two reliable, open-source tools for this are ImageMagick and FFmpeg. Both are widely used and can be installed via common package managers.

Using ImageMagick for Conversions

ImageMagick is a versatile tool for image manipulation. Its magick command handles conversions between hundreds of formats and provides control over output quality.

Converting a single file is straightforward. This example converts input.avif to output.jpg while setting the JPG quality to 85:

ImageMagick conversion command

magick convert input.avif -quality 85 output.jpg

The -quality flag accepts a value from 1 to 100. A setting between 80-90 typically provides a good balance between visual detail and file size. This command can be easily integrated into any shell script.

The real power of the CLI is batch processing an entire directory of files with a simple loop. This eliminates manual repetition entirely.

Converting with FFmpeg

FFmpeg is primarily known for video, but it also has robust image transcoding capabilities. It is fast, efficient, and uses a clean syntax. If FFmpeg is already in your environment, it can handle your AVIF to JPG needs.

The basic command is similar to ImageMagick's:

FFmpeg conversion command

ffmpeg -i input.avif -q:v 2 output.jpg

The -q:v flag adjusts the quality. In FFmpeg, a lower value means higher quality, which is the reverse of ImageMagick's scale. A value of 2 is a good starting point for a high-quality JPG.

FFmpeg command breakdown

-i — Specifies the input file (input.avif)
-q:v 2 — Sets the quality scale to 2 (high quality)
output.jpg — Defines the output filename

The choice between ImageMagick and FFmpeg often depends on existing toolchains and personal preference. Both provide reliable automation for AVIF to JPG conversions.

Fine-Tuning Your Conversion: Quality, Color, and Metadata

A proper AVIF to JPG conversion requires attention to three factors: compression quality, color profile, and metadata. Managing these details ensures the final JPGs have sharp visuals, accurate colors, and an appropriate file size.

Balancing Quality and File Size

Both AVIF and JPG are lossy formats, meaning they discard some image data to reduce file size. The goal is to control how much data is lost during the conversion.

JPG quality is set on a scale from 1 to 100. A higher number means better quality and a larger file. A lower number reduces file size but can introduce visual artifacts.

Quality Range	Best For	Trade-off
90-100	Archival purposes where detail preservation is critical	Files will be large
80-89	Most web use, balancing quality and file size	Recommended default
60-79	When file size is the highest priority	Visible quality drop may be acceptable

A quality setting of around 85 is a reliable compromise for web images.

Preserving Color Profiles

Inconsistent color display is often caused by color profile issues. Color profiles like sRGB provide instructions to devices on how to display colors accurately.

Color profile considerations

AVIF supports a wider color gamut than standard JPGs. During conversion, it is important to ensure the color profile from the AVIF file is transferred to the new JPG.

If this step is missed, colors can appear washed out. Always ensure your final JPG is tagged with the sRGB color profile—it is the web standard and provides the most consistent color rendering across devices.

Managing EXIF Metadata

Images contain hidden information called EXIF metadata. This can include camera settings, lens information, and GPS coordinates. The decision to keep or strip this data is important.

When to keep or strip metadata

Strip for privacy — Removing metadata from images posted online is a good practice, especially if they contain GPS coordinates or personal information.
Keep for archives — For professional photography or personal archives, this data can be valuable for organization and cataloging.

Conversion tools should provide an option to manage metadata. You can learn more about how metadata is handled in our privacy documentation.

Frequently Asked Questions

Is converting AVIF to JPG a lossy process?

Yes, it is. Both AVIF and JPG are lossy compression formats. Converting from AVIF to JPG involves re-compressing an already compressed file. This process will inevitably result in some additional data loss.

The goal is to achieve a visually lossless result. By setting the JPG export quality to a high value (e.g., 90 or above), the output can appear visually identical to the source AVIF file. The resulting JPG will be larger than the original AVIF.

Which conversion method should I use?

The best method depends on your specific task:

Online Tool: Fastest for converting a single file or small batch
Bulk Online Converter: Good for converting a folder of images without scripting
Command-Line Tool: Best for automation, integration, and precise control

Your primary goal determines the best tool. If preserving exact color data is critical, you need a tool with more control over color profiles.

Why is a dual image format strategy useful?

Maintaining two image pipelines—AVIF for the web, JPG for other uses—provides the best of both worlds. Switching from JPG to AVIF can reduce image file sizes by 40-60%. This improves site speed and Core Web Vitals.

However, many internal tools for design and marketing do not yet support AVIF. Generating JPGs remains necessary for internal approvals, partner submissions, and other business workflows.

Why do I need to convert AVIF to JPG?

You need to convert AVIF to JPG for compatibility. While AVIF is a modern, efficient format for web delivery, it is not universally supported.

Many common platforms still require JPG:

Older web browsers that lack AVIF support
Email clients, which are notoriously slow to adopt new formats
Social media platforms with strict upload requirements
Legacy business software (CRMs, DAMs) and hardware

Converting to JPG ensures your images are viewable by the widest possible audience across all devices and platforms.

What JPG quality setting should I use for web images?

For most web images, a quality setting between 80-85 provides an excellent balance between visual quality and file size. At this range, compression artifacts are minimal and typically imperceptible to most viewers.

Use higher settings (90+) only for hero images or cases where quality is paramount. Lower settings (70-79) can work for thumbnails or situations where smaller file size matters more than fine detail.
