All image converters
Every converter on this site is the same engine underneath — decode in your browser, re-encode in your browser, nothing uploaded — with sensible defaults and notes specific to each pair. Pick the direction you need.
From HEIC (iPhone photos)
From JPG
- JPG to PNGMostly useful for compatibility or before repeated edits, not quality
- JPG to WebPAbout two thirds smaller at the same visual quality
From PNG
- PNG to JPGHuge win for photos accidentally saved as PNG — no transparency
- PNG to WebPSame size win as PNG to JPG, but transparency survives
From WebP
- WebP to JPGFor software that still does not recognise WebP
- WebP to PNGCompatibility, with transparency intact — expect a bigger file
Compression
What stays the same everywhere
Nothing is uploaded on any of these pages — every conversion decodes and re-encodes the image using your browser's own APIs, and you can verify that yourself in DevTools' Network tab on any of them. The 60 MB per file, 40 images per batch and 300 MB per batch limits are the same everywhere too, and exist only so a phone browser does not run out of memory — not to ration anything.
What is not the same everywhere is what survives the trip. Only JPG output carries Exif metadata across, and only from a JPG or HEIC source — each converter page above states exactly what applies to that specific pair, since the honest answer is genuinely different depending on the two formats involved.
