To use Favicon Generator, open the tool, choose your file, and let it process in your browser — nothing is uploaded. Convert any image to favicon set in your browser. No upload, no watermark. The result downloads straight to your device, free and without sign-up.
Favicon Generator converts a picture from one image format to another directly in your browser, so you get a file your intended destination — a website, an app or a form — actually accepts.
What Is Favicon Generator?
Favicon Generator converts a picture from one image format to another directly in your browser, so you get a file your intended destination — a website, an app or a form — actually accepts.
How to Use It — Step by Step
- Open Favicon Generator and select the source image.
- The tool converts the file format in your browser.
- Preview the converted image.
- Download the new file in the target format.
Why Use This Tool?
- Makes a hard-to-open format such as HEIC, AVIF or JFIF usable everywhere by converting it to JPG or PNG.
- No need to install a codec pack or dedicated conversion app.
- Everything happens locally in your browser, not on a server.
- There's no limit on how many images you convert, and it's free.
Supported File Formats
Favicon Generator accepts: AVIF, BMP, GIF, JFIF, JPEG, JPG, PNG, WEBP. Always confirm the accepted formats on the tool page itself if you are working with an unusual file type.
Quality, Resolution and File Size Considerations
Converting between formats can affect quality and transparency. JPG does not support transparency and always applies some compression; PNG is lossless but keeps a larger file size; WebP can do either, depending on settings. Converting a JPG to PNG will not restore detail already lost to JPEG compression — the source format's limitations carry through.
Is It Safe and Private?
Favicon Generator runs its processing in your browser using your device's own resources. The tool code does not make an upload request for the file you select, so your file is not sent to a server for this task. Keep in mind that no tool can guarantee what happens after you download and share a file elsewhere — that depends on where you send it next.
Best Practices
- Prefer converting from the source file over a copy that's already been compressed once.
- Use PNG or WebP when transparency matters; converting to JPG fills transparent areas with solid colour.
- Double-check that the target app or site actually requires the new format first.
- Make sure the converted file opens correctly before you delete the original.
Common Problems and Fixes
Transparency disappeared after conversion JPG cannot store transparency. Convert to PNG or WebP instead if you need to keep a transparent background.
The file looks lower quality than expected Converting to a lossy format like JPG applies compression. If quality matters most, convert to PNG instead, at the cost of a larger file.
The browser won't open the source file Some formats such as HEIC are captured by phone cameras but not opened by every browser; if the tool doesn't accept it directly, check the exact accepted formats listed on the tool page.

It can, depending on the source and target formats, but format conversion and compression are different operations — use a dedicated compression tool if size is the main goal.
