Good to know
Converting to PNG doesn't add quality or transparency that wasn't in the JPG — it stores the same image in a lossless format, so the file gets bigger. To remove a background, use the background remover.
Quick answers
Why is the PNG so much bigger?
PNG is lossless: it stores every pixel exactly instead of compressing like JPG.
Why use this converter
- HEIC that actually works on Windows and Android — iPhone photos are decoded with libheif (WebAssembly) right in the page. Safari users get the built-in decoder.
- Private — no upload, no account, no queue. Convert family photos or ID scans without sending them anywhere.
- Batch + ZIP — drop dozens of files, download them one by one or as a single ZIP.
- Strips location data — the new files have no EXIF, so sharing them doesn't reveal where they were taken.
Which format should I pick?
- JPG — photos you'll share or upload anywhere. Works everywhere.
- PNG — screenshots, logos and graphics with text or transparency. Lossless, bigger files.
- WebP — websites. Usually 25–35% smaller than JPG at the same quality, keeps transparency.
- AVIF — the smallest files, if your browser can create them (the option only appears when it can).
Frequently asked questions
How do I convert HEIC to JPG on Windows?
Drop the .heic files here and keep “JPG” selected. The first HEIC file loads a 1 MB decoder once; after that each photo takes about a second.
Is there a file limit?
No fixed limit. Files are converted one at a time to keep memory low, so even a phone can handle a big batch.
Why is my PNG bigger than the original JPG?
PNG is lossless, so it stores every pixel exactly — photos become much larger. Use JPG or WebP for photos.
Are animated GIFs kept animated?
No — the first frame is converted to a still image.
