JPG to AVIF Converter
Convert JPG to AVIF locally with Browser. See output settings, step-by-step instructions, format limitations and common questions.
JPG to AVIF
Convert a JPG image into AVIF for an upload form, website or editing app that expects that format. The converter decodes the image and writes a new file rather than renaming the extension. The output retains only the features supported by the destination image format.
- Prepare a AVIF copy for a service that does not accept JPG.
- Set an output width while retaining the original source file.
- Create a delivery copy with the settings your next app needs.
How to use JPG to AVIF
Select your JPG files
Use Select File or drop supported JPG files into the upload area. Each file creates a separate AVIF result. Check that the filename extension matches the contents and that the original opens correctly before adding a larger batch.
Choose the output settings
Open Options beside a selected file. Width, Quality are available for this JPG to AVIF operation. Save options to apply them to that file; other files in a batch can use different settings.
Convert to AVIF
Select Convert to add the files to the local queue. Files run one at a time, with real progress where the engine provides it. You can cancel a queued or running job and retry a failed result after correcting its input or settings.
Download and check the result
Selections and completed jobs stay available while you navigate inside this tab. Use My files to revisit results. Reloading or closing the tab clears the workspace; download results you want to keep first.
Understand the settings
- Width (pixels; 0 keeps original)
- Set the output width in pixels. Use 0 to keep the original width; proportions are retained. Default: 0.
- Quality
- Choose a value from 1 to 100. Higher values keep more detail and may produce larger files. Default: 85.
Choose settings for the destination
Start with a 2400-pixel-wide JPG image. Set Width to 1200 to create a narrower copy while retaining its proportions. Compare the default quality with a lower value if file size matters. Keep the original if you may need another export later.
Check your result
Inspect small text, fine edges, orientation and transparency at the intended display size. Standard format-pair conversion uses the first frame or page and removes metadata. Use the dedicated animation tools for moving GIF/WebP/APNG, or metadata tools when inspection or removal is the specific task.
Source and output formats
About JPG
Uses lossy compression to keep photographs compact. JPEG does not support transparent backgrounds.
About AVIF
Compresses images using AV1 encoding and supports transparency. Creating an AVIF can take longer than creating a JPEG.
What to know before you start
- Files are processed on this device. Browser memory and engine-specific limits apply. Save results before reloading.

JPG to AVIF: common questions
How do I convert JPG to AVIF?
Choose your JPG files, review Options and the format notes, then select Convert. Download the finished AVIF copy and check it in your destination application. Each input is processed independently; the original file remains unchanged.
Are all frames and metadata preserved?
Image conversion processes the first frame or page and removes metadata. Check the format limits above before converting an animated or multi-page image.
Which settings can I change for JPG to AVIF?
Width (pixels; 0 keeps original): Set the output width in pixels. Use 0 to keep the original width; proportions are retained. Default: 0. Quality: Choose a value from 1 to 100. Higher values keep more detail and may produce larger files. Default: 85.
Will the result be smaller or better quality?
A successful AVIF conversion does not guarantee a smaller file or recovered detail. Container overhead, compression and the selected settings all affect output size. Check the saved result and keep the source if you might need a different export.
Why did my JPG file fail?
Read the message beside the file. A mismatched extension, corrupt data, unsupported feature or resource limit can prevent conversion. Check that the source opens normally, try the default settings and retry. The app will not offer a successful download for a failed job.
Where are files processed and how long are they kept?
Processing runs in this browser, on your device. Files and pasted input are not uploaded to a conversion server. The website and required engine assets must load first; large operations depend on available device memory.
