Is WebP always the best choice?

For the web, usually — it's smaller than JPEG and PNG at similar quality and supports transparency. The exceptions are when you need a file that opens everywhere with zero doubt (send a JPEG) or you're handing artwork to a print shop (send the original).

Will converting JPG to PNG improve the quality?

No. The detail lost when the JPEG was saved is already gone — wrapping it in PNG just makes a bigger file with the same quality. Convert to PNG only when you need transparency or lossless editing from here on.

Does converting between formats lose quality?

Converting to a lossless format (PNG) doesn't. Converting to a lossy one (JPEG, WebP) re-compresses and loses a little each time, so convert from the original rather than from an already-compressed copy.

JPG, PNG or WebP: which image format should you use?

Useful Hacks Team·August 29, 2026

There's no single best image format — each one trades quality, file size and compatibility differently. Here's how to choose.

Image Converter

Convert images between JPG, PNG, WebP and AVIF — in batches, with quality control.

Open Image Converter

JPEG

Good at: photographs, anything with smooth colour gradients. Small files, opens on literally everything.
Bad at: sharp edges, text and line art (they get fuzzy halos), and transparency (it has none).
Use it for: photos you email, upload to older systems, or need maximum compatibility for.

PNG

Good at: screenshots, logos, icons, diagrams, anything with flat colour, crisp text or transparency. Lossless — it stores the image exactly.
Bad at: photos. A photo saved as PNG can be 5–10× larger than the same photo as JPEG with no visible benefit.
Use it for: graphics with transparency, or images you'll keep editing and re-saving.

WebP

Good at: almost everything on the web. Smaller than JPEG for photos, smaller than PNG for graphics, and it supports transparency and lossless mode.
Bad at: universal compatibility outside browsers — some older desktop apps and email clients still don't read it.
Use it for: images on a website you control.

Quick decisions

Photo for a website: WebP, or JPEG if you need the reach.
Logo or screenshot with transparency: PNG, or WebP.
Photo for email or an upload form: JPEG.
Making a photo smaller: convert PNG → JPEG or WebP with Image Converter, then Compress Image.

Open Image Converter to switch formats, one file or a batch.
