Converts TIFF files to ICO format — professional photography, print publishing, and document scanning with high color depth to favicons and app icons. All conversion happens locally in your browser with no file size limits.

TIFF to BMP output is not produced here — TIFF input may not decode in browsers, and Canvas cannot encode BMP, so conversion fails locally. Convert TIFF to PNG/JPG/WebP instead — local, unlimited saves.
TIFF to JXL output is not produced here — TIFF input may not decode in browsers, and Canvas cannot encode JXL, so conversion fails locally. Convert TIFF to PNG/JPG/WebP instead — local, unlimited saves.
JXL to TIFF output is not produced here — JXL input may not decode in browsers, and Canvas cannot encode TIFF, so conversion fails locally. Convert JXL 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.
TIFF (Tagged Image File Format) uses lossless (supports layers) encoding and is best for professional photography, print publishing, and document scanning with high color depth. ICO (Windows Icon) uses lossless (multiple sizes) encoding and excels at favicons and app icons — standard format for website bookmarks and Windows application icons. 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.
Two barriers at once: TIFF input may not decode in browsers, and Canvas cannot encode ICO. The run ends in Conversion failed before any save.
Moot — no ICO is emitted from TIFF input, so no size set builds. Convert TIFF to PNG for icons and favicons instead.
For TIFF 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.
ICO to TIFF
ICO to TIFF output is not produced here — ICO input loads, but Canvas cannot encode TIFF, so conversion fails locally. Convert ICO 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.
