Convert Image Formats Online for Free, Right in Your Browser

You take a photo on your iPhone and it saves as HEIC, a format half your apps refuse to open. You export a graphic as AVIF and a client asks for a JPG. You need a PNG with transparency but your source is a WebP. Format mismatches are a daily annoyance, and the usual online converters answer them with signups, daily limits, watermarks, and a server upload of files that are often personal.

Upsampler's Free Image Converter converts between the formats people actually use, all inside your browser. Nothing is uploaded, there is no account, and there is no cap. Your files stay on your device from start to finish.

Formats You Can Convert

The converter reads a wide range of inputs, including the two that trip people up most:

• HEIC and HEIF from iPhones and modern cameras
• AVIF, the newer high-efficiency web format
• JPG, PNG, WebP, GIF, and BMP, the classics

You can convert any of those into JPG, PNG, or WebP, the three formats that work almost everywhere.

How to Convert an Image

1. Open the Free Image Converter in any modern browser.
2. Add your image by dragging it in, pasting with Ctrl+V, or clicking to browse.
3. Choose an output format: JPG, PNG, or WebP.
4. Set the quality if you picked a lossy format. A slider from 10 to 100 percent appears for JPG and WebP; 90 percent keeps the conversion visually identical to the original. PNG is lossless, so no slider is shown.
5. Download the converted file. The tool shows the original format and size next to the new format and size.

Which Format Should You Choose?

JPG

The universal choice for photographs. Every device and app opens it, and it compresses photos to small sizes. Note that JPG has no transparency, so transparent areas become white.

PNG

Best when you need transparency or pixel-perfect graphics, logos, screenshots, and illustrations. It is lossless, so quality is preserved exactly, at the cost of larger files.

WebP

The modern middle ground. It supports transparency like PNG and compresses like JPG or better, making it ideal for websites. Support is now near-universal in browsers, though a few older desktop apps still lag.

Why This Converter Is Different

It runs 100 percent in your browser

Conversion happens locally using your device's own decoders, including a WebAssembly decoder for HEIC. Your files are never uploaded, so private photos and documents stay private.

The HEIC problem, solved

Converting HEIC to JPG is the single most common reason people reach for a converter, and this tool handles it without asking you to install anything or hand your photos to a server.

No limits and no watermark

Convert one image or a hundred. There is no signup, no daily cap, and nothing stamped on the output.

Convert, Then Compress or Resize

Converting changes the format but keeps the pixel dimensions. If you also want a smaller file, run the result through the Free Image Compressor, or change its dimensions with the Free Image Resizer. All three run in your browser with no uploads.

Frequently Asked Questions

Is the image converter free?

Yes, completely. No signup, no watermark, and no limit on how many images you convert.

How do I convert HEIC to JPG?

Load your HEIC photo, choose JPG as the output format, and download. It all happens in your browser with no upload.

Are my files uploaded to convert them?

No. Every conversion runs locally in your browser, so your images never leave your device.

Does converting lose quality?

Converting to PNG is lossless. Converting to JPG or WebP uses a quality slider; at 90 percent the result is visually identical to the original for photos.

What happens to transparency when I convert to JPG?

JPG does not support transparency, so any transparent areas become white. Choose PNG or WebP if you need to keep transparency.
