Convert Images

Turn one image format into another at full quality. iPhone HEIC photos into JPG, WebP into PNG, a PNG into a favicon.

Convert HEIC photos from an iPhone to JPG

iPhones save photos as HEIC, and very little outside Apple's own apps will open one. Drop them here, choose JPG, press Convert, and they open everywhere.

Nothing needs installing and the photos do not go anywhere; the HEIC decoder runs on your own computer. If the photo has to be lossless, perhaps for printing or editing, choose PNG instead of JPG. Expect PNG files to be several times larger.

Convert WebP to JPG or PNG

Images saved from the web are often WebP now, and many older programs refuse them. Drop them in and choose JPG for photographs or PNG for anything with a transparent background, since JPG cannot hold transparency and would fill it with white. If you are not sure which, PNG is the safe choice; it never loses anything.

Changing the file extension by hand does not work, by the way. The name changes but the bytes inside are still WebP, and programs read the bytes.

Convert JPG or PNG to WebP for a website

If the images are for a site you run, go the other way: choose WebP. Photographs come out around a quarter to a third smaller than the equivalent JPG with no visible change, and graphics converted from PNG are written in WebP's lossless mode, so they are smaller and still pixel-exact. Every current browser displays WebP. The one reason not to is if the images will be downloaded and opened in older desktop software, which may not.

For the smallest files of all, AVIF beats WebP again, at the cost of a few more programs that cannot open it. If size is the goal rather than format, the compressor can write WebP or AVIF and lets you choose the quality as well.

JPEG to JPG, and what to do with a JFIF file

JPEG and JPG are the same format; the three-letter version exists because old Windows could not handle four-letter extensions. A site that insists on .jpg will accept a file renamed from .jpeg, and the converter will do the rename for you if you prefer. JFIF is also a JPEG underneath, saved by some Windows apps with an extension almost nothing recognises. Drop it in, choose JPG, and it comes out as an ordinary JPEG file.

Choose a format

FormatChoose it whenWorth knowing
JPGPhotos that must open anywhereNo transparency; clear areas become white
PNGLogos, screenshots, anything transparentLossless, so files are larger
WebPImages for a websiteSmaller than JPG and PNG; every current browser opens it
AVIFThe smallest file possibleSmaller still, but some older apps can't read it
ICOA faviconOne file holding every standard size from 16 to 256 px
The five output formats and when each one makes sense.

Whatever you choose, conversion is done at the highest quality setting. Lossy formats (JPG, WebP, AVIF) are saved at quality 100, and when the source is itself lossless, such as a PNG going to WebP, the WebP is written in its own lossless mode so the pixels are exactly preserved. Converting is about changing the container, not shrinking the file; if you want smaller files, run the results through Compress afterwards. The Next step tiles do that in one click.

Make a favicon from a PNG

  1. Start with a square image, ideally a PNG at 256 × 256 or larger. A logo with a transparent background works best.
  2. Drop it in and choose ICO under Convert to.
  3. Press Convert and download the .ico file. It contains 16, 32, 48, 64, 128 and 256 pixel versions, which is what browsers and Windows look for.

If the source is smaller than 256 pixels, only the sizes it can fill are included; a 64-pixel logo gives you 16, 32, 48 and 64. Nothing is enlarged, because a blurry favicon is worse than a missing size.

Convert many images at once

Drop a folder, or keep adding with the + tile, and choose one output format for the lot; the button changes to Convert 24 to JPG. Mixed sources are fine, so a folder of HEIC, PNG and WebP all comes out as JPG. When it finishes, one download gives you a ZIP. The format you chose is also kept in the address bar, so you can bookmark a link such as /convert/?to=jpg that opens the tool ready to go.

Frequently asked questions

Will converting lose quality?

To PNG, never. To JPG, WebP or AVIF, the image is re-encoded at the maximum quality setting, so any difference is well below what you can see. If you convert the same photo back and forth many times you will eventually notice, but one conversion is not a concern.

What happens to a transparent background?

PNG, WebP, AVIF and ICO keep it. JPG cannot hold transparency, so the clear areas become white.

Can I convert a GIF?

Yes, but an animated GIF becomes a still image of its first frame, because the converter produces single images. For a static GIF, PNG or WebP is a straight swap.

Why did my PNG come out as a JPG by default?

When every image in the batch is already a PNG, the tool proposes JPG rather than offering to convert PNG to PNG, which would do nothing. You can pick any other format.

Are my photos uploaded anywhere?

No. Everything on this page runs inside your browser, so the files never leave your device. That is also why there is no file size limit and why the tool keeps working if your connection drops.
