Converts JPEG files to HEIC format — photographs, web images, and social media where smaller file size matters more than perfect quality to Apple device photos. All conversion happens locally in your browser with no file size limits.

WEBP to HEIC output is not encodable in browsers — Canvas has no HEIC encoder, so conversion fails locally. For Apple workflows convert WEBP to JPG or PNG instead — local, unlimited saves.
Request PNG to HEIC output for Apple storage — but browsers have no HEIC encoder, so Canvas conversion fails locally instead of downloading. For Apple sharing convert PNG to JPG instead — local, unlimited saves.
TIFF to HEIC output is not produced here — TIFF input may not decode in browsers, and Canvas has no HEIC encoder, so conversion fails locally. Convert TIFF to PNG/JPG/WebP instead — local, unlimited saves.
Convert animated GIFs to modern WebP or WebM formats with transparency support — ~10x smaller files. Shrink GIFs dramatically for modern web use — local conversion, unlimited saves.
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.
JPEG (Joint Photographic Experts Group) uses lossy compressed encoding and is best for photographs, web images, and social media where smaller file size matters more than perfect quality. HEIC (High Efficiency Image Container) uses lossy or lossless encoding and excels at Apple device photos — iPhone and Mac default format with excellent compression efficiency. 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.
In theory HEIC halves JPG bytes, but this browser tool cannot encode it — expect Conversion failed. Use JPG-to-WebP for real savings.
No. Both are lossy formats. HEIC is more efficient, so you get similar quality at smaller file sizes. It does not restore detail lost in the original JPG compression.
No HEIC is produced, so compatibility is moot — JPG and WebP outputs open everywhere with no extension needed.
None — there is no quality control; JPG output uses fixed 0.92 and WebP 0.85. The HEIC path fails before quality matters.
Yes. All conversion runs in your browser — the HEIC attempt fails locally with no upload.
HEIC to JPG
Convert HEIC images to JPG format in your browser. Photos never leave your device — processing runs locally in your browser with Canvas and WebAssembly.
Bulk Image Format Converter
Convert image batches between JPG, PNG, WebP, and AVIF 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). 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.
