Convert JPG images to AVIF format in Chromium browsers (Chrome/Edge encode AVIF via Canvas; Firefox/Safari refuse with guidance — use WebP there). Photos never leave your device — processing runs locally.
JPG to GIF
Convert JPG photos to GIF in your browser — each JPG still encodes to a single-frame GIF locally via the bundled gif.js worker. Stills-only output flattens transparency to white, and downloads are unlimited since nothing is uploaded.
HEIC to GIF
Convert HEIC photos to GIF in your browser — each HEIC still encodes to a single-frame GIF locally via the bundled gif.js worker. Stills-only output flattens transparency to white, and downloads are unlimited since nothing is uploaded.
Base64 Encode/Decode
Encodes text or small files into Base64 strings and decodes them back with automatic MIME-type detection for binary safety. Code never leaves your device — formatting and validation run locally in your browser.
Favicon Generator
Generate favicon packages — PNG icons plus Apple touch icons — from one image. Note: the .ico file is PNG data renamed (modern browsers only). Ship every platform icon in one pass — local generation, unlimited saves.
Frequently Asked Questions
Why convert JPEG XL to AVIF?
JPEG XL (JPEG XL) uses lossy or lossless encoding and is best for next-gen image archival — better compression than JPEG with support for wide gamut and HDR. AVIF (AV1 Image File Format) uses lossy or lossless encoding and excels at next-gen web images — royalty-free format with better compression than WebP and JPEG. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
Why convert between JXL and AVIF instead of just using one?
JXL has better lossless compression while AVIF has wider browser support. Converting JXL to AVIF lets you use your library of JXL images on websites where AVIF is better supported.
Which format produces smaller files?
For lossy compression at the same quality level, AVIF and JXL produce similarly sized files. JXL edges ahead in lossless mode, while AVIF has a slight advantage in lossy at low bitrates.
Will the conversion change my image dimensions?
No. A 3000x2000 JXL becomes a 3000x2000 AVIF. Only the file format and compression change — pixel dimensions stay identical.
Is JXL supported in browsers?
JXL has limited browser support — Chrome had it briefly, then removed it. Firefox supports it behind a flag. If you need web compatibility, convert to AVIF or WebP instead.
Does the converter handle animated JXL files?
No. This tool converts single-frame JXL images only. Animated JXL sequences are not supported in this version.

AVIF to JXL output is not produced here — AVIF input decodes, but Canvas cannot encode JXL, so conversion fails locally. Convert AVIF to PNG/JPG/WebP instead — local, unlimited saves.
Bulk Image Format Converter
Convert image batches to JPG, PNG, WebP, AVIF, GIF, BMP, ICO, or SVG outputs (JPEG/PNG/WebP/AVIF/HEIC/HEIF/GIF/BMP/ICO/SVG inputs; HEIC via heic2any, SVG rasterized at intrinsic size or 1024px fallback) with a quality slider (10–100, default 80; applies to lossy encodes). Pair pages (?from/?to) preset the output. Flat ZIP renamed per file — local, 5-file guest batches, 25 signed-in, 500 Pro.
Image Format Converter
Convert one browser-decodable image to PNG, JPG, or WebP — the only outputs canvas can encode. HEIC/SVG/JXL/TIFF and other exotic targets fail honestly instead of pretending. Nothing is uploaded; every conversion runs in your browser.
