How it works
- Drop your files in the zone above (or click it, or paste with Ctrl+V).
- They convert instantly, right in your browser — nothing is uploaded.
- Adjust quality or max width if needed; files reconvert automatically.
- Download files one by one, or everything at once as a ZIP.
About the formats
HEIC
HEIC (High Efficiency Image Container) is the format Apple has used for iPhone and iPad photos since iOS 11. It stores images with the HEVC codec, which keeps files roughly half the size of an equivalent JPG at the same quality. The catch: support outside the Apple ecosystem is patchy — many Windows apps, Android devices, websites and printing services still refuse HEIC files.
JPG
JPG (JPEG) is the most widely supported image format ever made — every camera, phone, program and website accepts it. It compresses photos efficiently but doesn't support transparency, and each re-save at low quality degrades the image a little more.
What this conversion actually gives
Measured with the converter on this page, on a 2016 × 1512 px test image: the HEIC file weighs 474 KB.
| Setting | Result | Change |
|---|---|---|
| Quality 85 % (default) | 608 KB | +28 % |
| Quality 60 % | 293 KB | −38 % |
| Max width 1600 px, quality 85 % | 353 KB | −26 % |
Converting to JPG makes the file bigger here (+28 %): HEIC relies on a newer, more efficient codec than JPG: at comparable quality, JPG simply needs more room.
For an email attachment, quality 60 % brings it down to 293 KB. Capping the width at 1600 px gives 353 KB — plenty for any screen.
- Transparent areas become white: JPG has no transparency.
- Camera model, date and GPS coordinates stored by the device are removed unless you tick « keep metadata ».
Your own files will differ — a photo full of detail compresses less well than a flat graphic. These figures come from one reproducible test image, not from an average.
Frequently asked questions
How big will my JPG file be?
On our 2016 × 1512 px test image, a HEIC of 474 KB comes out at 608 KB at the default quality (+28 %). Lower the quality slider or set a maximum width and the figure drops further — the page shows the new size as soon as the file is reconverted.
Why won't my iPhone photos open on Windows?
Windows needs paid HEVC codec extensions to display HEIC natively, and many apps never added support. Converting to JPG or PNG solves it permanently — the converted file opens on any device made in the last 25 years.
Does converting to JPG reduce image quality?
JPG uses lossy compression, but at a high quality setting the difference is invisible to the eye — and the file gets much smaller, ideal for photos and sharing. Pixloc lets you set the quality with a slider and adds a white background, since JPG has no transparency.
Are my files really private?
Yes. The conversion runs entirely in your browser using its built-in image engine. Your files are never uploaded, stored or seen by any server — you can even disconnect from the internet after the page loads and keep converting.
Is this free? Is there a file limit?
Completely free, no account, no watermark. Convert as many files as you like, up to 200 MB each — the only limit is your device's memory.
Can I convert many files at once?
Yes — drop a whole batch at once. Each file converts independently and you can grab everything in a single ZIP when done.
