How it works
Add your images
Drag and drop, paste, or pick files. They upload over an encrypted connection.
Pick a quality or a target size
Use the quality slider, or tell it exactly how many KB or MB you need.
Download
Save each file, or grab them all at once as a ZIP.
A photo taken on an iPhone cannot go onto a website as it is. Chrome and Firefox do not display HEIC at all, so most visitors would see a broken image. The usual fix is converting to JPG. If the photo is going onto a web page, WebP is the better target: it is shown by every current browser and is noticeably smaller than a JPG of the same quality.
Add HEIC photos and each comes back as a WebP at quality 80, a setting where photographs look clean at normal size. The orientation is applied, so portraits are upright. Location and camera data are removed, which is what you want for pictures that are about to be published.
Twenty photos convert at a time without an account. Safari opens each HEIC, the upload is encrypted, the conversion to WebP runs on our own servers, and both the photos and the results are deleted within one hour.
From camera roll to web page: resize as well
Changing the format is half of the job. An iPhone photo is 4032 pixels wide, or 8064 in the 48-megapixel mode, and a web page shows it at perhaps 800 to 1600. Publishing the full-size file makes every visitor download ten times the pixels they will see.
Open the Resize panel before you convert and set the width the page needs: 1600 pixels for a banner across the page, 1200 for a picture in an article, 600 for a thumbnail. At 1200 wide and quality 80 a typical photo is 100 to 180 KB as WebP. The same picture straight from the phone, converted without resizing, would be over a megabyte.
WebP, JPG, or AVIF
All three are possible from the same editor, and the choice depends on where the picture ends up. WebP is the safe default for anything shown in a browser: universal support there, files about a quarter to a third smaller than JPG, and transparency if you ever need it.
JPG is for everything outside the browser: email attachments, office documents, print services, upload forms that list their formats. AVIF is smaller again than WebP and worth choosing for large hero images on a site you control, bearing in mind that it takes longer to encode and that fewer tools outside browsers open it. Interestingly, AVIF is the closest relative of HEIC itself, so file sizes come out close to what the phone stored.
What the phone recorded and the web does not need
An iPhone photo carries the exact coordinates of where it was taken, the time and the phone model. Published with a picture of your home, your children's school or a client's premises, that is information you did not mean to give out. The conversion drops all of it, every time: a HEIC is opened by the browser before it reaches us, and the browser passes on the picture alone. Copyright and author fields go with it, so add them again in your publishing tool if you need them.
The extras of the HEIC format stay behind as well: portrait depth data, the HDR brightness layer and the video part of a Live Photo have no place in a WebP.
Frequently asked questions
Will the WebP be smaller than the HEIC?
At the same pixel size the two are similar, since HEIC is already efficient. The real saving comes from resizing to the width your page uses.
Can every browser show WebP?
Every current one, on desktop and mobile. HEIC, by contrast, is shown only by Safari.
Is the location removed from my photos?
Yes, always, together with the other camera data. For HEIC there is no option to keep it.
Which quality should I use?
80 suits most photos. Go to 85 or 90 for large images people look at closely, and to 70 for thumbnails.
Do the photos keep their colours?
They are converted from the iPhone's wide colour range to standard sRGB, which every browser shows consistently. The change is rarely noticeable.
Can I convert on the iPhone itself?
Yes. Open the page in Safari, choose photos from the library and save the WebP files to Files.
I am on Windows with HEIC files. What now?
This page cannot open them there, because no Windows browser decodes HEIC and neither do our servers. Open the page on the iPhone the photos came from, or in Safari on a Mac. Photos sent from the phone by Mail arrive as JPG, and the JPG to WebP page takes those anywhere.
