Rename Your AVIF Files Before Downloading

When you convert a JPG library to AVIF in bulk, the output files keep their original names — which means a folder full of DSC_0034.avif, IMG_2901.avif, and photo_final_v3.avif lands on your server with no structure. Before you download the ZIP, rename the entire batch in one step. Use the Sort By options to arrange files by upload order, name A→Z, or file size before applying names, so numbering and sequencing runs correctly across the converted set — or if renaming is your primary task, use the dedicated Bulk Image Renamer.

Add Prefix: Places a label at the start of every filename. Useful for organising AVIF files by project, client, or site section. Type product-avif- and every file becomes product-avif-001.avif, product-avif-002.avif — instantly identifiable when you are deploying to a web server or CMS media library.

Add Suffix: Places a label at the end of every filename before the extension. Good for version tracking when you are maintaining both JPG originals and AVIF converted copies in the same project folder. Type -avif and your files become hero-banner-avif.avif — clear at a glance which format each file is without opening it.

Find and Replace: Scans every filename and swaps a specific string across the whole batch. If your original JPGs were named with a legacy convention like img_ or photo_, use Find and Replace to update the entire set to your current naming standard in one pass — no manual renaming, no risk of missing files.

Auto Number: Appends a sequential number to every converted file. Essential when deploying an AVIF image set to a website where filenames need to be predictable and ordered — gallery pages, product grids, and image sliders all benefit from banner-001.avif, banner-002.avif rather than random camera roll names.

SEO Optimize: Converts every filename to a search-engine-friendly format — spaces become hyphens, uppercase becomes lowercase, special characters are removed. Since AVIF files are served directly from your web server or CDN, the filename becomes part of the image URL. red-running-shoes-product.avif is indexable by Google Image Search. IMG_2901 (1).avif is not.

How does the JPG to AVIF bulk converter work?

Simply drag and drop your JPG images into the converter. Our tool automatically compresses each one using advanced AV1 encoding through our secure conversion endpoint, intelligently batching files (5 at a time) so even large uploads process smoothly and reliably. Once conversion is complete, download your AVIF images individually or grab them all in one ZIP archive.

Can I convert multiple JPG files at once?

Will my converted images have watermarks?

No watermarks ever! All converted AVIF images are completely clean and professional, suitable for personal or commercial use without any branding or watermarks added to your files.

What is the difference between JPG and JPEG?

There is no difference—JPG and JPEG are identical formats. The 3-letter “JPG” extension originated from Windows file naming limitations, while “JPEG” is the full format name. Our converter supports both .jpg and .jpeg file extensions seamlessly.

Can I convert JPG to AVIF without losing quality?

Our converter uses optimized lossy compression (quality-tuned for the best balance of size and clarity), which is how most AVIF conversions are done for web use — it delivers dramatically smaller file sizes with no visible quality loss in the vast majority of images. Note that our tool doesn’t currently offer a separate lossless mode; if you need pixel-perfect, 100% lossless output for archival or professional use, keep your original JPG as the source file and use AVIF specifically for web delivery.

How much smaller are AVIF files compared to JPG?

AVIF files are typically 30-50% smaller than equivalent-quality JPG files. In many cases, an AVIF image at the same file size as a JPG will display noticeably better quality. Actual savings depend on image content, complexity, and compression settings used.

Do all browsers support AVIF images?

AVIF is supported by over 90% of browsers globally, including Chrome 85+, Firefox 93+, Safari 16+, and Edge 121+. For older browsers, implement fallback images using the

Is bulk JPG to AVIF conversion supported?

Yes! Upload as many JPG images as you like — there’s no cap on total files. Our smart batching automatically processes AVIF conversions in efficient groups to keep large jobs running smoothly, then download everything as a single ZIP archive for maximum efficiency.

Absolutely! All converted images remain your property. Use them freely for personal or commercial projects, websites, applications, marketing materials, or any other purpose without restrictions or attribution requirements.

What file sizes does the converter support?

Each image can be up to 15MB and up to 8000×8000px — generous limits that comfortably cover everything from thumbnails to large high-resolution photographs. There’s no limit on how many images you can upload in total, so batch away.

Does transparency get preserved when converting JPG to AVIF?

JPG format doesn’t support transparency, so there’s no transparency to preserve. However, AVIF does support full alpha channel transparency. If you need transparent images, consider converting PNG to AVIF instead to maintain transparency information.
