Format flexibility
Compress, resize, convert, crop and more in one place.
image tools
Convert between popular image formats.
The Image Converter switches between JPG, PNG and WebP so you always have the right format for the job — a smaller WebP for the web, a lossless PNG for logos, a JPG for photos.
Conversion runs locally in your browser, keeping your files private.
Choose the image you want to convert.
Select JPG, PNG or WebP from the dropdown.
Process the file and download it in your chosen format.
Built and maintained by the W3Tech team that ships production websites and SEO campaigns every week, this tool is held to the same standard we use on our own client work.
Every image utility is used in W3Tech projects, where image bloat is one of the first performance issues we eliminate.
Images are handled by the browser canvas — your files are never uploaded to a server.
What you see on the preview is exactly the file you download.
The tools rely on mature browser standards, so they keep working as the platform evolves.

Everything works in the tab you already have open.
Image weight is one of the most common reasons pages fail Core Web Vitals. Compressing, resizing and converting your images directly improves LCP and CLS — thresholds Google uses to evaluate rankings.
Sites that ship lean, correctly-formatted images across every page consistently beat heavier competitors in performance scores. It is one of the cheapest ranking wins available.
Run the site's images through the compressor and converter to see the weight gap.
Replace oversized originals with correctly sized WebP or compressed JPG files.
A faster, lighter site flips bounce rates and Core Web Vitals in your favour.
Almost every W3Tech project starts with an image-weight clean-up, so we built the tools we reach for daily — and are giving them away. Compressing photos should be free, local and instant.
Our mission is to remove the most common performance excuse there is: images too heavy to fix. Do it here, in seconds, without uploading a single file.
Use WebP for web photos to save bandwidth, PNG for logos and graphics with transparency, and JPG for photograph-heavy workflows.
Converting between lossy formats can cause generational loss. Converting once to WebP usually preserves visual quality while shrinking size.
