About our image tools
BestMint's image tools are unusual in one important way: they never upload your files. Every conversion, compression, resize and encoding runs through the HTML Canvas API in your own browser. That means you can drop in screenshots containing private data, photos still under embargo, or proprietary assets without worrying about a server-side cache, an ad-tech pixel, or a leaked URL.
The five image tools cover the most common day-to-day needs: the Image Format Converter switches between PNG, JPG and WEBP with a quality slider; the Image Compressor reduces JPG, PNG or WEBP file size with a side-by-side preview so you see exactly what each quality setting trades; the Image Resizer scales to exact pixel dimensions or by percentage with optional aspect-ratio lock; the Image to Base64 tool produces data URIs ready to paste into HTML, CSS or JSON; and the Favicon Generator outputs the full favicon set (16, 32, 48, 180 and 512 px) from any square source.
Because everything is browser-based, performance scales with your hardware. A modern laptop will compress a 10 MB photo in well under a second; phone browsers will be slower but still local. There is no upload limit, no daily quota, and no watermark on the output.
