HEIC to WebP Converter
You want to put iPhone photos on a website, but HEIC is not something browsers show, and you would like smaller files than plain JPG. This page converts HEIC to WebP in your browser tab, with a quality slider and resizing, so you can prepare web photos without handing them to any online service.
How to convert HEIC to WEBP
- Add your HEIC files by dropping them, clicking the drop zone or pasting.
- The output format is already set to WEBP. Adjust quality or size if you need to.
- Press Convert and compare the original and new size for each file.
- Download each file or all of them as a ZIP.
When to convert, and when not to
- You are preparing phone photos for a website or blog.
- You want a web-friendly format and your audience uses current browsers.
- You are comparing WebP with JPG on your own photos.
- Do not convert if the photos go to e-mail, print shops or older programs; JPG is the safer format there.
What changes
- The HEIC is decoded first and then compressed again as WebP, so the quality setting matters.
- Your browser must be able to write WebP. If it cannot, the WebP button is disabled.
- Only the first image is converted. Live Photos give a still picture.
- Orientation is applied; shooting date and location are not kept.
- Compare file sizes with a JPG made from the same photo before you decide.
From phone photo to web photo
Photos straight from a phone are usually far bigger than a web page needs, in pixels and in file size. A page that shows an image a few hundred pixels wide gains nothing from a picture thousands of pixels wide.
Use the max size option to cap the dimensions, then pick a quality setting. Those two controls matter more for page weight than the choice of format alone.
Remember that a web page shows pictures at the size of the space, not their full size. If your layout never goes beyond a certain width, there is no benefit in publishing a photo larger than that.
Checking WebP against JPG
WebP was created for the web, and for many photographs it gives a smaller file than JPG at a similar look. The amount varies by picture, so we do not claim a number here.
The easy test is to convert the same HEIC to both formats at comparable settings and read the sizes in the list. Look at both images at full size on your screen before deciding.
Pay attention to the quality setting. Going very low saves bytes but can leave visible blocks in skies and skin. A moderate setting is a sensible starting point, and you can raise or lower it after viewing the result.
When you view the results, zoom in on edges, such as a roof against the sky or text on a sign, because compression artefacts tend to appear there first.
Working in batches
A gallery may involve dozens of pictures. The converter handles files one at a time and shows a progress count, and you can collect the results in a ZIP file.
On a phone, memory is limited, so process groups of photos rather than a whole camera roll at once. Keep the browser tab open until the queue finishes.
If your page must work in every environment, publish a JPG as well and use the WebP only where the browser can show it.
Privacy: your files stay on your device
- The tool decodes, resizes and encodes your pictures with your browser. The files are never sent to a server.
- To check it yourself: open the browser developer tools (F12), open the Network tab, convert a file, and look for any request that carries your image. You will see none.
Frequently asked questions
Is WebP smaller than JPG?
Often, but it depends on the photo. Compare the sizes for your own files.
Why is WebP disabled in my browser?
Your browser cannot write WebP. Use a current Chrome, Edge or Firefox.
Will my site visitors see WebP?
Current browsers display it. Keep a JPG copy if you need to support old software.
Does the date or location stay in the file?
No. That information is not written to the WebP.
Is anything uploaded?
No. Conversion happens in this browser tab.
Can I use the WebP in e-mail?
Not reliably. Many e-mail programs do not show WebP, so use JPG for messages.
Which setting should I start with?
Begin with a moderate quality, check the result at full size, then adjust. Reducing the pixel dimensions usually saves more than lowering quality.
