Converts WebP files to HEIC format — modern websites to Apple device photos. All conversion happens locally in your browser with no file size limits.
Runs on Canvas

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.
JPG to HEIC output is not encodable in browsers — Canvas has no HEIC encoder, so conversion fails locally. For smaller Apple-friendly files convert JPG to WebP or keep JPG — 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.
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.
Design simple logos with text, tagline, and 5 preset icons on canvas — export PNG/SVG. Draft startup marks in an afternoon — local Canvas work, unlimited saves.
WebP (Web Picture Format) uses lossy or lossless encoding and is best for modern websites — Google-recommended format with superior compression for faster page loads. 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.
Moot — no HEIC is produced. PNG output preserves WEBP transparency; JPG fills transparent areas white.
No HEIC is emitted — JPG and PNG outputs open everywhere with no extension needed.
None — no quality control exists; JPG output uses fixed 0.92 and WebP 0.85.
Yes. All of the attempt runs in your browser — the HEIC path fails locally with no upload.
HEIC to WebP
Convert HEIC images to WEBP 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.
Batch Image Converter
Convert a batch of images to one output — JPG, PNG, or WebP — at quality 10–100% (default 80%), capped at 4096px longest side, then download everything as a ZIP. Files that fail conversion fall back to their originals inside the same archive — local library work.
