About Image Converter

iFormat is a free online image converter for changing image formats quickly without installing desktop software. You can convert images online between JPG, PNG, WebP, HEIC, AVIF, TIFF, GIF, BMP, and SVG formats for websites, ecommerce uploads, design workflows, social media, and everyday sharing.

Choosing the right image format affects more than compatibility. It changes file size, loading speed, transparency support, print quality, and how sharp graphics look on different screens. JPG is usually best for photos and broad compatibility. PNG works well for transparent graphics and screenshots. For web performance, WebP and AVIF often deliver smaller files at similar visual quality — a 500 KB JPEG can drop to 200 KB as WebP with no visible difference.

This page is the broad image format hub. If you already know the exact conversion you need, use a dedicated tool such as HEIC to JPG, WebP to PNG, or PNG to JPG. If you are comparing formats, deciding how to reduce image size, or simply need a general online image converter, start here.

How to Use the Image Converter Online

Convert images online in three quick steps. Change image format, improve compatibility, or prepare files for web, print, email, and mobile sharing without installing software.

Upload Your Image

Drop image files into the converter or click to browse. Upload JPG, PNG, WebP, HEIC, AVIF, GIF, BMP, TIFF, and SVG files. You can convert one image or batch convert multiple images together.

Choose Output Format

Select the best target format for your use case: JPG for broad compatibility, PNG for transparency, WebP or AVIF for smaller web images, and TIFF for print workflows. Most image conversions finish in seconds.

Download Instantly

Download converted images one by one or as a ZIP for batch jobs. Files are automatically deleted within 24 hours, which keeps your online image conversion private and temporary.

Why Use iFormat Image Converter

Choose the Right Image Format for Every Use Case

Use JPG for universal compatibility, PNG for transparent graphics, WebP and AVIF for web performance, and TIFF for print quality. Choosing the right image format helps you avoid upload failures and preserve the result you want.

Reduce Image File Size for Web and Mobile

Converting to JPG, WebP, or AVIF can often make image files much smaller. Smaller files load faster, use less bandwidth, and support better user experience on mobile devices and slower networks.

Keep Transparency for Logos and UI Assets

JPG does not support transparency. Convert to PNG or WebP when working with logos, icons, and design assets that need clean transparent backgrounds.

Handle Modern Formats Like HEIC, WebP, and AVIF

Photos from iPhones are often HEIC, while many websites and apps use WebP or AVIF. Convert these files when compatibility matters, or keep modern formats when better compression is the priority.

Fix Compatibility Issues Across Devices and Apps

If an image will not open in your browser, app, CMS, or email workflow, converting it to a more common format such as JPG or PNG usually resolves the issue quickly.

Batch Convert Images for Faster Workflows

Upload multiple files and convert them in one run instead of exporting each image manually. Batch output is packaged as a ZIP to speed up publishing, editing, and delivery workflows.

Image Converter FAQ

Quick answers about supported formats, common conversion workflows, and how to choose the right image conversion path.

What is an image converter?

An image converter is a tool that changes one image file format into another. You can use it to convert images online between formats such as JPG, PNG, WebP, HEIC, AVIF, TIFF, GIF, BMP, and SVG when you need better compatibility, smaller file sizes, transparency support, or improved web performance.

How do I change an image from one format to another?

Upload your image, choose the output format that fits your use case, and download the converted file. For example, JPG is usually best for broad compatibility, PNG is better for transparency, and WebP or AVIF are often the best options when you want smaller web images with strong visual quality.

What image formats can I convert online?

The image converter supports common image formats including JPG, JPEG, PNG, WebP, HEIC, AVIF, TIFF, GIF, BMP, and SVG. Available input and output options depend on the exact format pair, so if you already know the conversion you need, you can also use a dedicated format page such as HEIC to JPG or WebP to PNG.

What is the best image format for web use?

For most websites, WebP is a strong default because it usually keeps good visual quality at smaller file sizes than JPG or PNG. AVIF can compress even more in many cases. PNG is better for transparent graphics, logos, and sharp interface assets, while JPG remains useful when you need maximum browser, app, and CMS compatibility.

When should I use JPG vs PNG vs WebP?

Use JPG for photos and everyday sharing when compatibility matters most. Use PNG for screenshots, graphics, and images that need transparent backgrounds. Use WebP when you want smaller files for websites without giving up much visual quality. If you are optimizing website speed, WebP is often the best choice, while PNG remains the safer option for transparent design assets.

Will converting an image reduce file size?

It often does, but the result depends on the source file and target format. Converting large PNG, TIFF, or BMP files to JPG, WebP, or AVIF can reduce file size substantially. If preserving exact pixels or transparency matters more than file size, PNG may still be the better target even though the file stays larger.

Does converting an image affect quality?

Sometimes. Lossy formats such as JPG and WebP can remove some visual data to make files smaller, while lossless formats such as PNG preserve exact pixel detail. In practice, the best format depends on the job: photos can usually be compressed more aggressively, while logos, screenshots, and print assets often benefit from lossless output or higher-quality settings.

Can I batch convert images online safely?

Yes. You can upload multiple image files and convert them in one run, then download the results as a ZIP archive. The converter is designed for quick, private online use, and uploaded files are only kept temporarily before they are deleted automatically.
