What Is an Image Converter?

An image converter changes the file format of an image — for example, converting a JPG to PNG, or a PNG to WebP — without changing the pixel dimensions. Each image format has different characteristics: JPEG uses lossy compression for photos, PNG uses lossless compression for graphics, and WebP is a modern format that achieves the best file size for web use.

This tool converts between JPG, PNG, and WebP in your browser. No server upload, no account required. Supports HEIC (iPhone photos) as input.

When to Convert Each Image Format

Convert to JPG when…

The destination requires JPEG: email attachments, government form uploads, print workflows, older CMS that strips other formats. JPG is universally supported — every application, device, and browser opens JPG files.

Convert to PNG when…

You need transparency (logo on a colored background, UI element with transparent areas), exact color accuracy without compression artifacts, or lossless quality for screenshots and graphics. PNG is ideal for anything that is not a photograph.

Convert to WebP when…

You are uploading images to a website, WordPress, or any modern web platform. WebP is 25–35% smaller than JPEG at the same visual quality. All modern browsers support WebP. Converting blog photos and hero images to WebP improves page load speed.

Convert HEIC to JPG when…

You have iPhone photos (.heic files) that need to be shared or uploaded. Most platforms, apps, and government portals do not support HEIC. Upload the HEIC file here — it converts to JPG automatically during the conversion process.

Does Converting Change Image Quality?

·Visually identical at comparable quality
·Best choice for web performance

PNG → JPG

·Quality change (lossless → lossy)

·File size drops significantly
·Not suitable for logos with transparent backgrounds

Convert Images for Specific Platforms

WordPress

WordPress 5.8+ accepts WebP uploads natively. Convert JPG blog photos and hero images to WebP before uploading for 30–35% smaller files. Use PNG only for logos and graphics that require transparency or exact color rendering.

Email clients

Gmail, Outlook, and Apple Mail do not support WebP. Always attach JPG for photos. For inline email images (newsletters, marketing), JPG at quality 80 gives the best size-to-compatibility ratio. Avoid PNG — too large for email.

Shopify / eCommerce

Shopify automatically converts uploaded images to WebP for browsers that support it. Upload JPG at full resolution — Shopify handles optimization. For product images on other platforms, WebP at 800–1200px gives the best load time.

Government & exam portals

Most government portals in India, UK, and US require JPG/JPEG format specifically. HEIC (iPhone) and WebP are not accepted. Upload your HEIC or PNG file here, convert to JPG, then upload to the portal.
