Converts ICO files to PNG format — favicons and app icons to graphics with sharp edges, text overlays, screenshots, and images requiring transparent backgrounds. All conversion happens locally in your browser with no file size limits.
Runs on Canvas

Extract and convert Windows icon files to JPEG format in bulk. Developers and designers repurpose favicon assets as full-size images for social media. Everything runs locally in your browser — nothing is uploaded.
Turn a PNG (or JPG/WebP) into SVG two ways: Embedded Vector Wrapper (full-size base64 image in an SVG shell — scales without re-saving, not true vectors) or Silhouette Path Trace (black-only 1px-rect tracing of dark pixels on a capped 250px thumbnail). Downloads as traced_vector.svg — local Canvas work, no uploads.
Rasterize SVG vectors to crisp PNGs at 1x, 2x (default), 3x, or 4x scale — base size read from the SVG width/height attributes (100px fallback) — with filename preservation (.svg becomes .png). Developers ship full icon sets in four runs — local Canvas work, 2 free batches a day.
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.
Extract PDF content into editable DOCX files. Preserves formatting, tables, and layout — review complex layouts after conversion.
ICO (Windows Icon) uses lossless (multiple sizes) encoding and is best for favicons and app icons — standard format for website bookmarks and Windows application icons. PNG (Portable Network Graphics) uses lossless encoding and excels at graphics with sharp edges, text overlays, screenshots, and images requiring transparent backgrounds. 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.
The largest embedded size, for maximum quality to work down from.
Yes — icon alpha channels carry into the PNG at full embedded size.
Yes — PNG to ICO rebuilds multi-size favicon files from your PNG when needed.
No — conversion runs locally in your browser; unlimited saves on local tools.
PNG to ICO
PNG to ICO output is not produced here — browsers have no ICO encoder, so Canvas conversion fails locally instead of downloading. Convert PNG 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.
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.
