100% processed in your browser — Images are processed on your own device using the browser Canvas API. No file is ever sent to a server, and every piece of EXIF metadata (GPS location, camera model, capture time) is stripped from the converted result.
WebP is typically 25-35% smaller than JPG at the same visual quality. AVIF goes even smaller, but only some browsers can create it.
Applies to JPG, WebP and AVIF only. Around 80-85% is usually the sweet spot between file size and image quality.
The ICO file contains every size you select. 16, 32 and 48 px is the minimum set worth shipping for a favicon.
Advanced options
For example cover.jpg becomes cover-converted.webp. Leave it empty to keep the original name.

How to convert an image format
1. Add your images
Drag one or more images into the box above, or click the button to pick files. You can select many at once, including HEIC photos shot on an iPhone.
2. Choose the output format
Pick JPG, PNG, WebP, AVIF or ICO. If your goal is a lighter website, WebP or AVIF are the strongest choices.
3. Tune quality and size
Drag the quality slider to balance file size against sharpness, and set a maximum width or height when your images are larger than they need to be.
4. Download the results
Hit convert, then download images one by one or grab them all in a single ZIP. Every converted file has its EXIF metadata removed.
Which image format should you use?
Every image format has its own strengths. This table is a quick way to match a format to what you are actually doing with the image.
| Format | Best for | Notes |
|---|---|---|
| JPG / JPEG | Photos, product shots, article cover images | Opens on every device and in every app, but it has no support for transparency. |
| PNG | Logos, icons, screenshots, anything needing transparency | Lossless compression keeps quality intact, at the cost of a bigger file than JPG. |
| WebP | Almost every image on a modern website | Roughly 25-35% smaller than JPG at the same quality, and it supports transparency. Every mainstream browser can display it. |
| AVIF | Sites where load speed matters most | The smallest of the common formats, though creating AVIF inside the browser is only available in some browsers. |
| HEIC / HEIF | Original photos shot on an iPhone or iPad | Many websites and Windows apps cannot open HEIC, so it usually needs converting to JPG or WebP before sharing. |
| SVG | Vector logos and illustrations | Scales to any size without losing sharpness. When converting to PNG or JPG, set a large enough size because the result is a pixel image. |
| ICO | Favicons shown on browser tabs | A single ICO file can hold several sizes so the browser and operating system can pick the right one. |
| GIF | Simple animations and stickers | This tool takes the first frame only from an animated GIF. |
| BMP | Files exported by older Windows software | Barely compressed and therefore very large, so converting it to something else is almost always worth it. |
Tips for optimising images for the web
- Do not serve images larger than you need: if it renders at 800px wide, there is no reason to upload a 4000px file.
- For photos, WebP at 80% quality is visually hard to tell apart from the original while being far lighter.
- Keep PNG for logos and icons that need transparency, and use JPG or WebP for photographs.
- Lighter images improve Largest Contentful Paint, which is one of Google's ranking signals.
- Strip EXIF metadata before posting photos publicly so you do not accidentally share the GPS location where they were taken.
- Give files meaningful names and write alt text that genuinely describes the image to get more out of image SEO.
