Whether you just bought a new iPhone (which saves photos as HEIC) or received a WebP file that won't open in your editing software, you need a reliable image converter. And once the image is sorted, you often need a quick utility too — a compressor, a resizer, a calculator. Most tools are paid, full of ads, or require you to create an account just to download your file.
We tested over a dozen tools and shortlisted the five that are genuinely free, fast, and work without any friction. Here's what we found.

1. ConvertLinx — Best overall free image converter
ConvertLinx.com
ConvertLinx is a clean, fast utility tools platform with 10+ image tools — HEIC to JPG, image compression, format conversion, and cropping — all without creating an account. Files are processed client-side where possible, so your images never leave your device unnecessarily.
Try ConvertLinx Free →What makes ConvertLinx stand out is the breadth of tools in one place. Most free converters do one thing — ConvertLinx covers image conversion, compression, and cropping all together, alongside everyday utility tools. Especially useful if you're processing iPhone photos that need to go from HEIC → JPG → compressed for web.
Pro tip: If your images need to become a PDF at the end of the workflow, convert them first on ConvertLinx, then use PDFLinx's Image to PDF tool to finish the job.
2. FreeConverto — Best for image, PDF and utility tools in one place
FreeConverto.com
FreeConverto bundles around 28 free tools on one site: image tools, PDF tools, AI tools and everyday utilities. Its image converter handles JPG, PNG, WebP, AVIF, GIF and HEIC with batch conversion of up to 20 images, and the image compressor and resizer cover the usual follow-up jobs. On the utility side you'll find an age calculator, BMI calculator, sleep calculator and a grammar checker. Most tools run in the browser, with no signup and no watermarks.
Try FreeConverto Free →A good pairing: convert and compress photos on ConvertLinx, then jump to FreeConverto's utility tools when you need a quick calculator or text check.
3. CloudConvert — Best for rare formats
CloudConvert
Supports 200+ formats including TIFF, RAW, and obscure image types. The right choice when ConvertLinx doesn't support your specific format. The downside: a free account is required for extended usage beyond a few conversions per day.
4. Squoosh — Best for compression
Squoosh by Google
Built by Google Chrome Labs, Squoosh runs entirely in the browser using WebAssembly. It's a compression specialist — not really a format converter — but excellent for shrinking PNG or JPG files for web use with precise quality control and a live side-by-side preview.
5. iLoveIMG — Best for batch operations
iLoveIMG
The image counterpart to iLovePDF. Handles bulk operations well — resize, compress, convert, crop, and watermark multiple images at once. The free tier is generous but has a file size limit per conversion.
