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
AVIF
AVIF is the newest mainstream image format, built on the AV1 video codec. It beats WebP and JPG on compression, but software support outside modern browsers is still limited, so AVIF files frequently need converting for everyday use.
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 AVIF file weighs 200 KB.
| Setting | Result | Change |
|---|---|---|
| Quality 85 % (default) | 390 KB | +95 % |
| Quality 60 % | 203 KB | +1 % |
| Max width 1600 px, quality 85 % | 274 KB | +37 % |
Converting to JPG makes the file bigger here (+95 %): AVIF 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 203 KB. Capping the width at 1600 px gives 274 KB — plenty for any screen.
- Transparent areas become white: JPG has no transparency.
- An animated AVIF loses its animation — the first frame is kept.
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 AVIF of 200 KB comes out at 390 KB at the default quality (+95 %). 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 can't my photo editor open AVIF files?
AVIF is recent (2019) and many editors haven't added decoders yet. Your browser already decodes it though — which is exactly what this tool uses to convert it into a format your editor understands.
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.
