Image formats can be confusing: your phone saves HEIC, websites prefer WebP, forms demand JPG, and PNG shows up everywhere. Here's what each one is good at, so you always pick the right format — and how to convert when you need to.
JPG (JPEG) — the universal photo format
JPG and JPEG are the same format (just different extensions). It uses smart, lossy compression, which makes photographs small while still looking good — perfect for forms, email and uploads. It's the safest, most compatible choice for any photo. If you have a .jpeg file but need .jpg, our JPEG to JPG tool simply re-saves it.
PNG — for graphics and transparency
PNG is lossless and supports transparency, which makes it ideal for logos, screenshots and graphics with sharp edges. The downside: photo-style PNGs are large. If a PNG photo is too big for an upload, convert it with PNG to JPG to shrink it dramatically (note that JPG removes transparency, replacing it with white).
WebP — the modern web format
WebP is a newer Google format that's smaller than both JPG and PNG at similar quality, which is why websites love it. The catch is compatibility: some apps, editors and upload forms still won't open WebP. When that happens, convert it with WebP to JPG or WebP to PDF.
HEIC — what your iPhone uses
HEIC (HEIF) is Apple's space-saving format, the default on iPhones. It's efficient but poorly supported outside the Apple ecosystem — Windows PCs, many websites and forms can't open it. Convert iPhone photos with HEIC to JPG for images or HEIC to PDF for documents.
Quick recommendation
- Uploading a photo to a form? Use JPG.
- Logo or screenshot with transparency? Use PNG.
- Building a fast website? Use WebP, but offer JPG fallbacks.
- iPhone photo that won't open? Convert HEIC to JPG.
Whatever you have, the all-in-one image converter switches between PNG, JPG and WebP in a click — all in your browser, nothing uploaded.
