Image Converter

What image format conversion does

This tool converts images between JPG, PNG, and WebP, changing the underlying file format while keeping the visual content the same. Each format makes different trade-offs: JPG is a lossy format optimized for photographs and small file sizes, PNG is lossless and supports transparency, making it the standard for logos, icons, and graphics with sharp edges or text, and WebP is a newer format that generally achieves both smaller file sizes and transparency support, though it isn't yet universally supported by every legacy application.

Conversion runs locally in your browser, so your original image file is transformed on your own device rather than passed through a remote server.

Which format should you use?

Choose JPG for photographs and complex images where small file size matters more than perfect pixel accuracy — it's supported everywhere and compresses photographic detail well. Choose PNG when you need a transparent background, or when the image contains text, line art, or sharp edges that JPG's compression would blur. Choose WebP for modern websites where you want the smaller file sizes of JPG-level compression combined with PNG-style transparency support, keeping in mind that a small number of older tools and applications still don't accept it.

Common use cases

Website owners convert PNG graphics to WebP to shrink page weight without losing transparency. Designers convert a PNG logo to JPG when a platform's upload form doesn't accept PNG files. People convert HEIC photos from an iPhone into the more universally compatible JPG format so the image opens correctly on any device. Developers convert images to WebP as part of optimizing a site's Core Web Vitals scores, since image format is one of the more impactful, low-effort performance wins available.

Tips for choosing a format

If you're not sure whether a destination — an email client, a form, an older piece of software — supports WebP, converting to JPG or PNG is the safer bet, since both have been universally supported for decades. Converting a JPG to PNG won't restore quality lost during the original JPG compression; the conversion changes the container format but can't recover detail that's already gone, so always convert from the highest-quality original you have available.

Common use cases

People convert an iPhone's default HEIC photos into JPG so they open reliably on Windows PCs, older Android devices, and websites that don't accept HEIC uploads. Web developers batch-convert a site's PNG assets to WebP as part of a page-speed optimization pass. Designers convert a PNG mockup to JPG when a client portal or print vendor's upload form only accepts JPG files. Forum and marketplace users convert screenshots or product photos to whatever format a listing platform requires, since upload forms frequently reject formats outside a specific accepted list — and because conversion happens locally in your browser, none of these images need to pass through a third-party server just to change format, which matters if the photo includes anything personal or unpublished, from a draft product shot to a private family picture.
