Converts PNG files to HEIC format — graphics with sharp edges, text overlays, screenshots, and images requiring transparent backgrounds 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.
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.
PNG to TIFF output is not produced here — browsers have no TIFF encoder, so Canvas conversion fails locally instead of downloading. Convert PNG 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.
Converts HEIC files to PDF format — Apple device photos to document sharing, printing, and archival with consistent formatting. All conversion happens locally in your browser with no file size limits.
PNG (Portable Network Graphics) uses lossless encoding and is best for graphics with sharp edges, text overlays, screenshots, and images requiring transparent backgrounds. 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.
Unreachable in this browser tool: Canvas toBlob has no HEIC encoder, so PNG-to-HEIC ends in a local Conversion failed notice. Convert PNG to JPG for smaller Apple-friendly files instead.
Moot — no HEIC file is produced, so nothing carries over. JPG output fills transparency white; PNG and WebP outputs keep alpha.
Open the PNG originals or JPG conversions anywhere. No HEIC is emitted, so no HEIF extension is needed.
No — the attempt runs locally in your browser on Canvas and fails before any save. Local-tool downloads stay unlimited.

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.
