HEIC files can be converted from, but browsers can't save to HEIC — pick JPG, PNG or WEBP.

Why use this tool

  • No file size limit

    Full-size photos straight from your phone or camera.

  • Nothing is uploaded

    Processed entirely in your browser. Your files never leave your device.

  • No signup needed

    Open the tool and go. No account, no email.

Image formats exist for different jobs, and the one your camera, your phone or a website hands you is often not the one the next tool will accept. iPhones save HEIC that Windows will not open. Websites serve WEBP that design software refuses. Upload forms demand JPG. This converter moves an image between HEIC, WEBP, PNG and JPG in a single step.

The conversion happens in your browser with the Canvas API, so your file is never uploaded, there is no queue and no size cap, and what you download has no watermark on it. HEIC is decoded on the way in; because no browser can write HEIC, JPG, PNG and WEBP are the formats you can convert to.

How to convert an image

  1. Add your image

    Drag a HEIC, WEBP, PNG or JPG file into the box, or click to browse. Files are identified by their contents, so a renamed or mislabelled file still works.

  2. Pick the output format

    Choose JPG, PNG or WEBP. JPG for photos and anything that must be widely accepted, PNG when you need transparency, WEBP when you want the smallest file for a web page.

  3. Convert and download

    Press Convert Image. The converted file appears with its new size next to the original, ready to download.

Which image format should you choose?

JPG is the safe default for photographs. Every device, app and upload form accepts it, and its lossy compression keeps photos small. It cannot store transparency, and each re-save degrades it slightly.

PNG is lossless and supports transparency, which makes it right for logos, icons, screenshots, diagrams and anything with sharp edges or flat colour. The cost is size: a PNG photograph is typically several times the size of the same image as a JPG.

WEBP was built for the web and is supported by every current browser. It does both lossy and lossless compression, keeps transparency, and is usually 25–35% smaller than an equivalent JPG or PNG. The catch is that older desktop software and some upload forms still reject it.

HEIC is what modern iPhones and iPads shoot by default. It stores roughly the quality of a JPG in about half the space, but support outside Apple's ecosystem is patchy — which is why converting HEIC to JPG is the most common conversion people need.

What conversion does to your image

Pixel dimensions never change. A 4032 × 3024 photo comes out 4032 × 3024 whichever format you pick; only the encoding, and therefore the file size, is different.

Converting to JPG or WEBP re-encodes the image with lossy compression at a high quality setting, so the result is visually identical but not bit-for-bit the same. Converting to PNG is lossless, although converting a lossy original to PNG cannot restore detail that was already discarded — it simply stores what is there without losing more.

Transparency survives a conversion to PNG or WEBP. Converting a transparent image to JPG fills the transparent areas with white, because JPG has no alpha channel to store them in.

Metadata does not survive. EXIF tags — camera, lens, date and GPS coordinates — are dropped. Worth knowing before you convert a photo you rely on for that information, and useful before posting one publicly.

Common reasons to convert an image

  • HEIC won't open on Windows

    iPhone photos copied to a PC often show as blank icons in File Explorer. Converting to JPG makes them open anywhere.

  • A form only accepts JPG or PNG

    Application portals, government sites and marketplaces tend to allow two formats and reject everything else.

  • You saved an image from a website

    Right-clicking an image on a modern site usually gives you a WEBP file that older software will not open.

  • You're optimising a web page

    Serving WEBP instead of JPG or PNG typically cuts a quarter to a third off the weight of your images.

Frequently asked questions

Can I convert an image to HEIC?
No. Browsers can decode HEIC but none can encode it, so HEIC is an input format only. You can convert a HEIC photo to JPG, PNG or WEBP, but not the other way round — keep your original if you need the HEIC.
Does converting an image reduce its quality?
Converting to JPG or WEBP re-encodes at a high quality setting, so the result is visually identical to the original at normal viewing size. Converting to PNG is lossless. Nothing is resampled, so the image is never softened.
Are my files uploaded to a server?
No. The conversion runs inside your browser tab. Your image is read from disk into the page, converted there and handed straight back to you.
Can I convert several images at once?
One at a time. Each conversion takes a second or two and the page does not reload between files, so working through a handful is quick.
Does it work on iPhone and Android?
Yes. Any current mobile browser works, including Safari on iPhone and Chrome on Android, and you can choose photos straight from your camera roll.
Why is my converted PNG larger than the original?
PNG is lossless, so it stores every pixel exactly — including the compression artefacts a lossy original already contained. A PNG made from a JPG or WEBP is expected to be bigger. Choose WEBP if you want transparency and a small file.
Will transparency be kept?
Converting to PNG or WEBP keeps the alpha channel. Converting to JPG fills transparent areas with white, because JPG cannot store transparency at all.
Is there a watermark or a limit on free conversions?
No watermark, no daily limit and no account. The tool runs on your device, so there is nothing to meter.
