PNG vs JPG vs WebP: which image format should you use?

Use JPG for widely shared photographs, PNG when you need dependable transparency or crisp lossless graphics, and WebP when a modern website needs smaller files with either transparency or photographic detail. Keep the source file, then export the format that fits the final placement.

PNG, JPG, and WebP at a glance

Choose PNG for transparency and exact edges

PNG keeps pixels without the blocky loss caused by photographic compression. It works well for a subject with a transparent background, a screenshot with small text, or a graphic with flat colors and sharp edges. The cost is file size: a full-page photograph saved as PNG can weigh far more than a good JPG or WebP export.

For example, remove the background from an object with the background remover. Keep a transparent PNG or WebP when the object must sit over different colors. A JPG would replace the transparent area with a solid background.

Choose JPG for compatible photographic delivery

JPG is familiar to cameras, editors, print workflows, and content systems. It compresses continuous color and texture well, so it remains useful for a photograph sent to a client or uploaded to a system that does not accept WebP. It does not support transparency.

Save a fresh JPG from the best source available. Opening and resaving the same JPG again and again can soften edges and add visible blocks. Keep text and logos outside the file as HTML or vector artwork where possible.

Choose WebP for efficient web images

WebP can compress photographic detail and can also preserve transparency. That makes it a practical default for website galleries, cards, and many downloadable previews. Stockphoto.now uses smaller WebP files for Free downloads and browsing previews. Paid Premium members can choose from the original and the formats offered on each image page.

Match the export dimensions to the real layout. A 2,000-pixel image does not need to load inside a 300-pixel card. Read the resolution and aspect ratio guide before choosing dimensions.

A four-step image format decision

1. Does the image need transparency? Choose PNG or WebP.
2. Is it mainly a photograph? Start with WebP for the web or JPG for broad handoff compatibility.
3. Does it contain small text or crisp interface lines? Test PNG against WebP and inspect the edges.
4. Will someone edit it later? Keep the original source separately, even when the delivered copy is compressed.

Check image exports before publishing

Open the final file at its actual display size. Check gradients, hair, foliage, text edges, and transparent boundaries. Confirm the filename describes the image, record the image license, and use the WebP workflow to keep dimensions and page layout stable.
