Free, batch, and done entirely in your browser. Updated July 2026 · Reviewed by the PDFWix Team (https://www.pdfwix.com/about/team) A favicon is the tiny picture in the browser tab, the bookmark bar and the Windows shortcut — and each of those places wants a different pixel size. A proper .ico file solves that by holding several square images in one file, so the browser picks the sharpest one it needs. PDFWix PNG to ICO redraws your logo at every size you tick and packs them into a single favicon.ico, with transparency kept intact. To convert PNG to ICO free: open PDFWix PNG to ICO, add your PNG or JPG logo, tick the sizes you want (16, 32 and 48 px is the standard set), then click Create ICO file.

Ticking 16, 32 and 48 gives you the standard favicon.ico that works everywhere and stays under a few kilobytes. Modern sites usually pair favicon.ico with larger PNGs for phones and web apps — typically 180×180 for Apple touch icons and 192 or 512 px for Android. You can produce those with Resize Image (https://www.pdfwix.com/resize-image) once you have a square source. If your logo is a vector file, render it at a big size first with SVG to PNG (https://www.pdfwix.com/svg-to-png), because rasterising from the vector is always sharper than enlarging a small bitmap. ## How to convert PNG to ICO 1. 1 ### Add your logo Drag in a PNG (best, because transparency is kept) or a JPG. A square image gives the cleanest result. 2. 2 ### Tick the sizes 16, 32 and 48 px is the standard favicon set. Add 128 or 256 px for crisp desktop shortcuts. 3. 3 ### Choose fit or fill Fit keeps the whole logo with transparent bars; switch it off to fill the square and crop the long edge. 4. 4 ### Download and install Click Create ICO file, rename it favicon.ico, and upload it to the root of your website. ## Tips for making a favicon ### Start big and square Feed in at least a 256 px square image; use Crop Image (https://www.pdfwix.com/crop-image) to square it up first. ### Simplify the artwork At 16 px, fine text disappears. Use just the symbol or initials, not the full wordmark. ### Check it on dark themes A dark logo vanishes in a dark browser theme — add a light ring with Round Image Corners (https://www.pdfwix.com/round-corners-image). ### Vector source is best Render the logo at 256 px from the SVG using SVG to PNG (https://www.pdfwix.com/svg-to-png) before converting.

A real multi-size .ico beats a renamed PNG, because the browser can pick the size it needs. - **Every size in one file.** One favicon.ico covers tabs, bookmarks, taskbars and desktop shortcuts. - **Sharp at 16 px.** Each size is drawn separately, so tiny icons stay legible instead of turning into mush. - **Transparency kept.** PNG payloads keep the alpha channel, so your logo sits cleanly on light and dark browser themes. - **Private.** Unreleased logos and brand marks never leave your device.

Open PDFWix PNG to ICO, add the PNG, tick the sizes you need and click Create ICO file. It is free and runs in your browser. ### What sizes should a favicon.ico contain? 16×16, 32×32 and 48×48 is the standard set and covers browser tabs, high-resolution screens and Windows shortcuts. ### Does the ICO keep my transparent background? Yes. Each size is stored as a PNG inside the .ico file, so the alpha channel is preserved. ### Can I convert a JPG to ICO too? Yes, any JPG, PNG or WebP works. JPG has no transparency, so the background will be solid. ### Where do I put the favicon file? Rename it favicon.ico and upload it to the root folder of your site. Most browsers find it automatically. ### Is my logo uploaded anywhere? No. The resizing and the .ico file are built by your own browser, so nothing is sent to a server. ## More PDF tools ### SVG to PNG ### Resize Image ### Image Converter ### Round Image Corners Give photos neat rounded corners with a transparent background. https://www.pdfwix.com/round-corners-image ## Related PDF tools SVG to PNG: https://www.pdfwix.com/svg-to-png Resize Image: https://www.pdfwix.com/resize-image Image Converter: https://www.pdfwix.com/convert-image Round Image Corners: https://www.pdfwix.com/round-corners-image Merge PDF: https://www.pdfwix.com/merge-pdf Split PDF: https://www.pdfwix.com/split-pdf ## Structured data ```json [ { "@context": "https://schema.org", "@type": "WebApplication", "@id": "https://www.pdfwix.com/png-to-ico#app", "name": "PNG to ICO (Favicon) — PDFWix", "applicationCategory": "MultimediaApplication", "applicationSubCategory": "PhotoApplication", "operatingSystem": "Any — runs in browser on Windows, macOS, Linux, iOS, Android", "browserRequirements": "Requires a modern web browser", "offers": { "@type": "Offer", "price": "0", "priceCurrency": "USD", "description": "100% free online browser tool" }, "aggregateRating": { "@type": "AggregateRating", "ratingValue": "4.9", "ratingCount": "2145", "bestRating": "5", "worstRating": "1" }, "description": "Convert PNG to ICO online free.
