Favicon Generator
Generate favicon PNG files in all 6 standard sizes from any image — instant, no upload.
How to use this tool
- 1Click the upload zone and select a square image (PNG, JPG, SVG, or WebP).
- 2All six favicon sizes (16—16, 32—32, 48—48, 64—64, 128—128, 256—256) are generated instantly.
- 3Click the 'Save' link under each size to download that PNG individually.
About Favicon Generator
This favicon generator scales your uploaded image to six standard PNG sizes — 16, 32, 48, 64, 128, and 256 pixels — in the browser so you can download the set browsers and bookmarks expect without a full icon design suite.
Missing or blurry favicons show up on every tab. Shipping only one tiny size looks soft on retina displays. Generating the full set from a square master keeps marks consistent. Local processing avoids uploading unreleased brand assets to third-party icon sites.
Upload a square-ish PNG, JPG, SVG, or WebP. The tool draws each size with Canvas and lets you save individual PNGs. SVG masters usually scale cleaner than upscaled bitmaps. Non-square sources may letterbox or stretch depending on fit logic — start from a square canvas when you can.
Fine strokes vanish at 16×16 — design a bolder small-size variant when needed. Photographic favicons rarely read at tab size; simplify to a glyph. Downloading only one size when your checklist lists six invites QA failures.
Keep the vector or large master offline; treat generated PNGs as deploy artifacts you regenerate when the brand mark changes.
Frequently asked questions
Detail that works at 256 collapses at 16. Soft upscaling from tiny sources also destroys edges. Design a simpler small-size mark or start from a larger sharp master. Tiny-size illegibility is a design scenario, not a random generator bug. In practice, re-run Favicon Generator on a smaller sample after each change so you can see which input detail caused the mismatch. Keep the original nearby until you trust the export.
Fitting a non-square image into square favicons can pad or crop awkwardly. Place the mark on a square canvas with padding first. Re-upload the square master. Aspect-ratio mismatches are a common input scenario. In practice, re-run Favicon Generator on a smaller sample after each change so you can see which input detail caused the mismatch. Keep the original nearby until you trust the export.
Many generators will still emit sizes, including upscales that look soft. That is success technically and failure visually. Check previews at 1:1. Soft upscales are a quality scenario you must catch by eye. In practice, re-run Favicon Generator on a smaller sample after each change so you can see which input detail caused the mismatch. Keep the original nearby until you trust the export.
Modern stacks often use multiple PNG link tags plus optional apple-touch icons. ICO remains useful for legacy and some tooling. Generate PNGs here, pack ICO if required. Read your target browsers’ expectations rather than habit. In practice, re-run Favicon Generator on a smaller sample after each change so you can see which input detail caused the mismatch. Keep the original nearby until you trust the export.
Some browsers support SVG favicons, but PNG sets remain the compatibility workhorse. Generate PNGs when you need broad coverage or PWA assets. Keep SVG for where it works. Compatibility drives the derivative set. In practice, re-run Favicon Generator on a smaller sample after each change so you can see which input detail caused the mismatch. Keep the original nearby until you trust the export.
Favicons are aggressively cached. Bust cache with new filenames or hard refreshes, and confirm HTML paths. The generator cannot flush user caches. Cache stickiness is an operations scenario after a successful generate. In practice, re-run Favicon Generator on a smaller sample after each change so you can see which input detail caused the mismatch. Keep the original nearby until you trust the export.
PNG can keep alpha when the source had it and the pipeline preserves it. Verify against dark and light browser UI. Flat mats may be better for tiny sizes. Alpha at 16px can look noisy if edges are soft. In practice, re-run Favicon Generator on a smaller sample after each change so you can see which input detail caused the mismatch. Keep the original nearby until you trust the export.
Generation is intended to scale in-browser and download locally. That protects unreleased marks from icon-farm retention. Commit outputs to your repo under your normal review process. Clear the page after handling embargoed brand files. In practice, re-run Favicon Generator on a smaller sample after each change so you can see which input detail caused the mismatch. Keep the original nearby until you trust the export.
