Find your conversion

Say what you have and what you need. Every conversion here runs in your browser and tells you plainly what it costs — transparency, animation and file size do not all survive every direction.

What have you got? Two answers and you are there

Convert HEIC to JPG

Or see everything at once Down: what you have · Across: what you want
Source format to JPG to PNG to WebP
HEIC iPhone opens anywhere much bigger, no visible gain —
WebP opens anywhere keeps transparency —
AVIF opens anywhere keeps transparency —
PNG about 80% smaller — 30% smaller, keeps alpha
JPG — gets bigger, no gain smaller for the web
BMP about 95% smaller lossless, far smaller —
GIF — full colour, loses animation —

A dash means that direction is not offered here, usually because it makes the file worse for no benefit. Everything runs in this tab — nothing is uploaded.

Which format should you actually use

JPEG is the safe currency. Every piece of software made in the last thirty years opens it, it is small, and it is the right choice for photographs going anywhere you do not control. It cannot store transparency.

PNG is lossless and keeps transparency, which makes it correct for logos, icons, screenshots containing text, and anything you will edit repeatedly. The cost is size — often several times a JPEG of the same picture.

WebP is the modern web default: roughly 30 percent smaller than JPEG at similar quality, with transparency support. Every current browser reads it; plenty of desktop and print software still does not.

AVIF compresses better still and is the least supported outside browsers. Good for websites, awkward everywhere else.

HEIC is what iPhones produce. Efficient, and readable by almost nothing outside Apple's ecosystem, which is why converting it is so common.

GIF holds 256 colours and animation. BMP is essentially uncompressed and enormous. Both are legacy formats you convert away from rather than to.

The one rule worth remembering

Every conversion between two lossy formats — JPEG, WebP, AVIF and HEIC are all lossy — discards a little more detail, and that loss is permanent. Convert from your original file whenever you still have it, rather than converting a converted copy. Converting once is nearly invisible; converting the same image back and forth several times is not.
