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.
PNG
PNG is the standard lossless format: perfect quality, full transparency support, and universal compatibility. Its weakness is size — photographs saved as PNG are often 5–10× heavier than a visually identical JPG or WebP.
Frequently asked questions
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.
Will converting to PNG keep transparency and quality?
Yes. PNG is lossless, so no quality is lost, and it preserves transparent backgrounds — ideal for logos, screenshots and graphics with sharp edges. The trade-off is a larger file than JPG or WebP.
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.
