Which browsers can encode AVIF and WebP?

Encoding uses the canvas, so it depends on the browser: Chrome and Edge encode both, Firefox encodes WebP, Safari encodes WebP from version 17. The format list shows what your browser supports.

Does converting keep EXIF data?

No. Re-encoding through the canvas drops EXIF (including GPS) and colour profiles; the browser applies the orientation first so the result is upright. Keeping the original format without resizing preserves the file byte-for-byte.

Are my images uploaded?

No. Decoding, conversion and encoding all happen locally in your browser.

Image Converter & Base64

Drop, upload or paste an image to get a Base64 data URI with HTML, CSS, Markdown, JSX, srcset, <picture> and image-set() snippets — or convert it: change the format to PNG, JPEG, WebP or AVIF with a quality slider and live output size, resize by exact dimensions, maximum edge or scale factor, flatten transparency, and export a favicon set. Decode a data URI or raw Base64 back into a downloadable image, read the EXIF orientation, camera and date from JPEGs (and see that conversion strips it), and process files in batch. SVGs get a compact UTF-8 data URI. Everything runs in the browser with a 20 MB per-file guard.

Frequently asked questions

For very small images used in CSS or email, or when you want to avoid an extra request. Base64 adds about 33 % and cannot be cached separately, so photos should stay as files.
