How to Convert JP2 to AVIF — Quick & Free
Fast, instant JPEG 2000 to AVIF conversion. No signup required. Just drop your .jp2 file and get .avif in seconds.
Batch Settings
Color depth reduction: 16-bit → 12-bit
JP2 stores up to 16 bits per channel, but AVIF supports only 12 bits. You may notice banding in smooth gradients (like sky or skin tones) where subtle color transitions are lost.
About JPEG 2000 to AVIF Conversion
Short answer: yes, you can convert JP2 to AVIF online for free, and quality is well preserved with the right settings. Just upload your .jp2 file to CocoConvert, pick AVIF as the output, and click Convert. The whole process takes seconds.
Now for the details. JP2 (JPEG 2000) offers wavelet-based compression with better quality than JPEG at the same bit rate. AVIF is the newest image format based on AV1 video codec, delivering exceptional compression — up to 50% smaller than JPEG at the same quality. Converting between these two formats lets you optimize files for fast web delivery.
Full Name: JP2 uses JPEG 2000, while AVIF uses AV1 Image File Format. Compression: JP2 uses Lossy & Lossless, while AVIF uses Lossy & Lossless. Transparency: JP2 uses Yes, while AVIF uses Yes.
Your JP2 file is decoded and re-encoded as AVIF. Converting JP2 to AVIF maintains high quality with CocoConvert's optimised encoder settings.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.

What Happens When You Convert JPEG 2000 to AVIF
Your JP2 image is decoded into raw pixel data, then re-encoded as AVIF.
Your JP2 file is decoded — the compressed/stored pixel data is expanded into raw RGBA (with alpha channel) pixels
Pixels are re-encoded using AV1 Image File Format's lossless compression
Metadata (EXIF, ICC profiles) is transferred where AVIF supports it
The AVIF file is saved and ready for download

Frequently Asked Questions
Is JP2 to AVIF conversion free?
Yes. CocoConvert offers free JP2 to AVIF conversion with generous daily limits — 25 minutes of processing time and up to 5 files per hour (250 MB each). Pro plans remove these limits.
How fast is JP2 to AVIF conversion?
Most files convert in 2–10 seconds depending on size. Large image files may take 30 seconds. Batch jobs process in parallel for maximum speed.
What happens to my files after conversion?
Your uploaded JP2 file and the converted AVIF file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.
Does converting JP2 to AVIF lose quality?
Converting JP2 to AVIF maintains high quality with CocoConvert's optimised encoder settings.
Can I convert AVIF back to JP2?
Yes, CocoConvert supports AVIF to JP2 conversion as well. However, if the original conversion involved lossy compression, converting back won't recover the lost data.
Versions are pinned in our worker Dockerfile and re-built via CI on every change.
