Image Converter
Turn iPhone HEIC photos, WebP and AVIF downloads, PNGs and JPGs into the format you need, a whole batch at a time. The pictures never leave this device.
Key facts
- Reads WebP, AVIF, PNG, JPG, GIF and BMP, and HEIC in Safari; writes JPG, PNG or WebP, many files at once, with a ZIP download.
Drop images here
JPG, PNG, WebP, AVIF or HEIC, as many as you like. They become JPG files.
Your images are converted on this device and never uploaded. Location and other EXIF data are removed.

How this works
Method
Each image is decoded by the browser itself (HEIC only where the browser opens HEIC, as Safari 17 and later does: the site ships no HEIC decoder, because HEVC is covered by patents), turned upright from its EXIF orientation, resized if asked, and drawn on a canvas in a background worker, over your background colour for JPG. The browser’s own encoder writes JPG, PNG or WebP at your quality (libwebp where it can’t write WebP). Rebuilt from pixels, the file has no EXIF; if you keep metadata, the original EXIF is copied in with orientation reset and, unless you keep all, the GPS block emptied.

9 worked examples for this page are checked by automated tests before every release: given the inputs, the tool must show the expected answer.
Changes
- HEIC now opens only where the browser reads it (Safari 17+), with tips elsewhere; the bundled HEIC decoder was removed because HEVC is covered by patents.
- First version: HEIC, WebP, AVIF, PNG, JPG, GIF and BMP to JPG, PNG or WebP, in batches with a ZIP, metadata removed by default, and nine conversion pages.
Which format to choose
JPG is the safe choice for photos: every phone, computer, website and form accepts it, and its quality setting trades file size against detail. It has no transparency, so transparent areas are filled with a background colour you choose.
PNG is lossless: the pixels you save are exactly the pixels you get back, which suits screenshots, logos, diagrams and anything with text or a transparent background. Photos saved as PNG are much larger than as JPG.
WebP does both jobs in smaller files, lossy like JPG or lossless like PNG, with transparency either way. Every current browser shows it, but some desktop apps and upload forms still refuse it, which is why so many people convert WebP back to PNG or JPG.
HEIC and AVIF are newer, very efficient formats built on the same container (HEIF). The converter reads AVIF in every current browser and HEIC where the browser opens it, as Safari does, and writes JPG, PNG or WebP, because browsers can’t write HEIC or AVIF from a canvas.
Good to know

- Lossless WebP images are about 26% smaller than PNGs, and lossy WebP images 25–34% smaller than comparable JPEGs at equal SSIM quality. Source: Google for Developers: An image format for the Web (WebP)
- AVIF stores AV1-coded pictures in the HEIF container, the same container HEIC uses for HEVC-coded ones. Source: AV1 Image File Format (AVIF), Alliance for Open Media

How to convert images3 steps, all on your device
- Pick the format you need. Choose JPG, PNG or WebP at the top. JPG suits photos, PNG keeps transparency and sharp edges, WebP makes the smallest files for a website.
- Drop your images. Drag in one picture or a whole folder’s worth, or tap Choose images. Each one converts as soon as it arrives, in a background worker.
- Download. Save each file from the list, or all of them at once as a ZIP. Change the quality or size and they convert again.
Frequently Asked Questions
Are my images uploaded anywhere?
No. The converter runs in this browser tab, in a background worker, and no picture is sent to a server. The footer’s “On this device” counter shows what the page has sent: converting adds nothing to it. Close the tab and the files are gone from memory.
Is the location in my photos removed?
Yes, by default. The new file is drawn from the pixels, so it carries no EXIF metadata: no GPS position, camera model or capture time. Under More options you can keep the camera details without the location, or keep everything.
How many images can I convert at once?
As many as you like; they convert one after another and you can download them all as one ZIP. Very large photos are limited by your device’s memory: over 24 megapixels (16 on iPhone and iPad) a picture is scaled down to fit, and the list says so.
Which browsers does it work in?
Current Chrome, Edge, Firefox and Safari. AVIF needs Chrome 85, Firefox 93 or Safari 16.1 or later. HEIC photos open only in Safari 17 and later, which reads HEIC itself; in Chrome, Edge and Firefox the list says so and suggests other ways. The site ships no HEIC decoder of its own, because HEVC, the compression inside HEIC, is covered by patents.
