What is an image converter?
An image converter changes a picture from one file format to another — for example HEIC to JPG, or PNG to WebP. Each format balances quality, file size and compatibility differently, so converting lets you pick the right one for where the image is going: a website, an email, a print order or a chat app. This converter reads JPG, PNG, WebP, HEIC/HEIF, BMP and GIF and saves as PNG, JPG or WebP, entirely inside your browser — the picture never leaves your device.
How to convert an image
- Drop or select your image.
- Pick an output format (PNG, JPG or WebP) and adjust quality if needed.
- Click Download.
Convert HEIC to JPG
iPhones save photos as HEIC, which many apps and websites can't open. Drop a HEIC file here and choose JPG to get a universally compatible image — without uploading your photo to a stranger's server.

Which format should I choose?
- JPG — smallest size for photos; no transparency.
- PNG — lossless, supports transparency; best for graphics and screenshots.
- WebP — modern format, smaller than JPG/PNG at similar quality.
Common uses
- Turn iPhone HEIC photos into JPG so they open on Windows, older phones and websites.
- Convert PNG screenshots to JPG to email or upload them faster.
- Save photos as WebP to reduce page weight on a blog or online store.
- Convert old BMP images to JPG or PNG so modern apps can open them.
Tips for best results
- Use JPG or WebP for photos, and PNG for logos, icons and screenshots with sharp edges or transparency.
- For JPG and WebP, a quality of 85–95% usually looks identical to the original at a much smaller size.
- Converting to PNG never loses quality, but the file may be larger than the original.
Is it really private and free?
Yes. The converter runs as JavaScript in your browser tab using the built-in Canvas API, so the image is read and written on your own device and is never sent to a server. There is no sign-up, no watermark and no daily limit — the site is funded by ads instead.
FAQ
- Are my files uploaded?
- No. Conversion happens entirely in your browser; nothing is sent to a server.
- Can it convert HEIC from my iPhone?
- Yes — HEIC and HEIF inputs are supported and converted locally to JPG, PNG or WebP.
- Can I convert BMP images?
- Yes. BMP files can be opened and converted to JPG, PNG or WebP for free.
- Will converting reduce the quality?
- Converting to PNG is lossless. JPG and WebP use compression — keep quality at 85–95% for near-identical results.
- Is there a file size or daily limit?
- No limits. Because processing is local, you can convert as many images as your device can handle.
- Does it work on phones?
- Yes — it works in modern mobile browsers the same way as on desktop.
- Does it work offline?
- After the page loads, conversion works offline. HEIC input downloads a small helper the first time, which needs a connection on first use.
