Which browsers support AVIF conversion?

Chrome 85+, Firefox 93+, and Edge 121+ support AVIF encoding. Safari support is limited — if your browser cannot encode AVIF, try WebP instead.

Does converting between formats lose quality?

Converting to JPG, WebP, or AVIF involves lossy compression. At quality 90+, the loss is imperceptible. Converting to PNG is always lossless.

Can I convert multiple images at once?

Yes. Drop as many images as you need — they are all converted to the same target format in parallel.

What happens to transparency?

PNG and WebP preserve transparency. JPG does not support transparency — transparent areas will be filled with white.

What is the difference between WebP and AVIF?

Both are modern formats smaller than JPG. AVIF offers slightly better compression but is slower to encode. WebP has broader browser support and faster processing.

Which format gives the smallest file size?

WebP typically produces the smallest files (30% smaller than JPG). AVIF is even smaller but has less browser support. PNG files are largest but lossless.

Does conversion affect image quality?

Converting to lossless formats (PNG) preserves full quality. Converting to lossy formats (JPG, WebP) may slightly reduce quality depending on the compression level.

Can I convert animated images?

Static image conversion is supported. Animated GIF or WebP files will convert as a single frame. For animation preservation, use specialised tools.

How image conversion works

FileKit converts your images entirely in the browser using the Canvas API — no files are ever sent to a server. Simply drop one or more images, choose your target format, adjust quality if needed, and download. WebP and AVIF typically produce 25–50% smaller files than JPG at equivalent visual quality, making them ideal for web use.

How to Convert Image Formats

1
Upload your images
Drag and drop images in any common format — JPG, PNG, WebP, AVIF, GIF, or BMP.
2
Choose the target format
Select the output format you need. For web use, WebP offers the best size-to-quality ratio. For universal compatibility, choose JPG or PNG.
3
Convert and download
FileKit converts each image using the browser's built-in Canvas API. Download the converted files — quality settings are available for lossy formats.
