What image format should I use?

By Waleed Sheeraz, independent operator of A2Z Edit · Updated 2026-09-09

Pick formats based on content and destination—not habit.

A2Z Edit’s Convert Image hub and pair converters help you switch when a platform disagrees.

Do this on A2Z Edit

Open the Image Format Converters and follow the steps below.

Open Image Format Converters

Steps

  1. Photos for general sharing → JPG (convert HEIC first if needed).
  2. Graphics with transparency → PNG or WebP.
  3. Modern websites optimizing weight → WebP with fallbacks.
  4. Documents for offices → put images into PDF when required.
  5. Convert and compress to match the upload rules in front of you.

Why it matters

One thoughtful choice prevents rejection emails and blurry logos.

Tips

  • Keep a master file; export derivatives per channel.
  • Prefer browser-based conversion on A2Z Edit for quick one-offs.
  • Remove metadata on anything public-facing.

Match the destination, then the content

Start from where the file will live. Email and government uploaders still love JPG. Modern marketing sites should use WebP (with a JPG fallback if you support old browsers). App stores and print shops often want PNG for logos and JPG or PDF for photos.

iPhones save HEIC. Convert HEIC to JPG before you email a stranger. AVIF is excellent on the web you control and a nuisance in office software — convert it when a partner cannot open the original.

Keep a master

Do not overwrite the camera file with a tiny WebP. Export copies. Strip metadata on public copies. If a form wants both a photo and a PDF of documents, use Images to PDF for the packet and Compress Image for the portrait.

Frequently asked questions

Is there one best format?

No—best depends on photo vs graphic and where it goes.

What about GIF?

Mostly for simple animation; WebP/MP4 often replace it.

PDF instead of images?

Use Images to PDF when reviewers expect a document.
