Converts BMP files to HEIC format — legacy software compatibility, raw pixel data transfers, and simple image processing tasks to Apple device photos. All conversion happens locally in your browser with no file size limits.

ICO to HEIC output is not produced here — ICO input loads, but Canvas has no HEIC encoder, so conversion fails locally. Convert ICO to PNG/JPG/WebP instead — local, unlimited saves.
PNG to BMP output is not produced here — browsers have no BMP encoder, so Canvas conversion fails locally instead of downloading. Convert PNG to PNG/JPG/WebP instead — local, unlimited saves.
JPG to BMP output is not produced here — browsers have no BMP encoder, so Canvas conversion fails locally instead of downloading. Convert JPG to PNG/JPG/WebP instead — local, 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.
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.
BMP (Bitmap Image File) uses uncompressed encoding and is best for legacy software compatibility, raw pixel data transfers, and simple image processing tasks. 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.
Canvas has no HEIC encoder, so the run ends in Conversion failed with no file written. Convert BMP to PNG, JPG, or WebP for a working download.
Moot — no HEIC is emitted from BMP input. Convert BMP to JPG for Apple Photos instead.
For BMP sources: PNG for exact pixels, JPG for photos at fixed 0.92, or WebP at 0.85 — every one encodes locally with unlimited saves.
No — the attempt runs locally in your browser and fails before any save. Local-tool downloads stay unlimited.
HEIC to BMP
HEIC to BMP output is not produced here — HEIC input decodes via heic2any, but Canvas cannot encode BMP, so conversion fails locally. Convert HEIC to PNG/JPG/WebP instead — local, unlimited saves.
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.
