Frequently Asked Questions
Why convert JPG to AVIF?
AVIF is designed for efficient modern image delivery. It is useful for websites, ecommerce stores, content management systems, and applications that accept AVIF uploads.
What AVIF quality should I choose?
The default setting is a practical starting point. Choose a higher value when fine detail matters, or a lower value when a smaller file is more important. The completed file size is shown after conversion.
Will the AVIF always be smaller than the JPG?
Not always. The result depends on the original JPG, image detail, quality setting, and dimensions. Crest Convert shows the completed size so you can compare it with your original.
Can I resize the AVIF while converting?
Yes. Keep the original dimensions, choose 75%, 50%, or 25%, or enter a custom percentage from 10% to 100%. The width and height change together.
Does the AVIF keep JPG metadata?
The converted AVIF keeps the visible image but does not copy JPG EXIF details such as the camera model, date taken, or GPS location. Keep the original JPG when you need that information.
Can I batch convert JPG to AVIF?
Yes. Add multiple JPG or JPEG images, apply the same settings, and convert them together. Download each AVIF separately or download all completed files as a ZIP.
Are AVIF images supported everywhere?
AVIF works in current major browsers and many modern image tools, but some older software and upload forms may still prefer JPG or WebP. Keep the original JPG when broad compatibility matters.
How can I convert the AVIF back to JPG?
Use the AVIF to JPG converter when an application or upload form does not accept AVIF. The original JPG remains unchanged when you create the AVIF.
Are my JPG images stored?
Your image is processed securely for conversion and the temporary files are removed automatically. No account is required.
