Ever had this problem: you shot photos in HEIC and friends can't open them on WeChat; downloaded a WebP image that won't edit in Photoshop; or a system only accepts JPG but you only have PNG. All of these need image format conversion. Understand format conversion and these headaches disappear.

Differences between common image formats

Know the characteristics first so you convert in the right direction:

Format Features Use cases
JPG/JPEG Lossy, small, most universal Photos, web, almost everything
PNG Lossless, transparency, larger Icons, logos, transparent backgrounds
WebP Small, high quality, transparency Web loading, bandwidth saving
HEIC Apple photo format, small Native iPhone format
GIF Animation Animations, stickers
TIFF Lossless, professional Print, photography
SVG Vector, infinitely scalable Icons, illustrations, logos

In most cases, universality matters most. JPG is the most compatible format — nearly every app, system, and device opens it.

When to convert image formats

Common scenarios:

  • HEIC to JPG: iPhone photos uploaded to incompatible platforms
  • WebP to JPG/PNG: web downloads opened in old software
  • PNG to JPG: reduce size, remove transparency
  • JPG to PNG: need transparency or lossless quality
  • Image to WebP: shrink web images to speed up loading

Convert formats with an online tool

Converting with PixelForge Format Convert is simple:

Step 1: Upload images (batch supported). Step 2: Choose the target format, e.g., HEIC to JPG or PNG to WebP. Step 3: Download — conversion preserves quality automatically.

Everything runs locally in your browser; images never upload, and it's free.

Batch conversion tips

To convert a pile of images, use Batch Convert — upload all at once, convert uniformly, download in a package.

Tips:

  1. Confirm the target format first: know the final format to avoid repeated lossy conversions
  2. Convert once: repeated conversions degrade quality
  3. Keep originals: keep the source files separate from converted versions

FAQ

Does format conversion lose quality?

Depends on direction. JPG to PNG is lossless; PNG or WebP to JPG is lossy because JPG is itself lossy. Keep the original format when you can.

My WebP image won't open. What should I convert it to?

Convert to JPG or PNG. For everyday display and upload use JPG (small); for transparency use PNG. Convert online with [Format Convert](https://img-tools.top/convert) — no install needed.

How do I convert iPhone HEIC photos to JPG?

Upload the HEIC file to an online converter and choose JPG output. The converted photos open on all platforms and send easily.

Is it normal for the file to get bigger after converting?

Yes. For example, PNG to JPG usually shrinks, but JPG to PNG may grow. If size matters, compress the result with [Smart Compress](https://img-tools.top/compress).

Can I batch convert hundreds of images?

Yes. Online tools accept many images at once for batch conversion — great for organizing phone photos and site assets.
