WebP vs AVIF — Which Should You Use in 2025?
Both are modern, efficient formats. But which one is right for your website? We compare compression, quality, and browser support.
How to Reduce Image File Size Without Losing Quality
Large images slow down your website. Here's a practical guide to optimizing images for the web without visible quality loss.

What is an Online Image Converter?
An online image converter is a tool that transforms image files from one format to another — for example, converting a JPG photo to WebP for faster web loading, or a PNG logo to SVG-compatible formats for print use. ImageConvertFree is a free browser-based image converter that handles all processing locally on your device, without uploading files to any server.
Unlike traditional desktop software or cloud-based converters, this tool runs entirely in your browser using the HTML5 Canvas API. This means your images never leave your computer — making it the most private and fastest way to convert images online. There's no software to install, no account to create, and no file size limits.
Whether you need to convert JPG to WebP to improve website performance, change PNG to AVIF for next-gen compression, or convert TIFF to JPG for easy sharing, ImageConvertFree supports all major image format conversions in seconds.

Why Are There Different Image Formats?
Different formats are optimized for different use cases — choosing the right one matters for quality, file size, and compatibility.
JPG uses lossy compression to produce small files. It's the universal standard for photographs, product images, and any image with gradients. Supported by every device and application ever made.
PNG uses lossless compression and supports full transparency (alpha channel). Every pixel is preserved perfectly, making it ideal for logos, screenshots, and illustrations with sharp edges.
WebP is Google's format for the web. It's 25–35% smaller than JPG/PNG at the same quality and supports both lossy and lossless compression plus transparency. Supported by all modern browsers.
AVIF is the most efficient image format available today — up to 50% smaller than JPG with better quality. It supports HDR and wide color gamut. Supported by Chrome, Firefox, and Safari.
TIFF is the professional standard for print and photography. It supports lossless compression, very high bit depths, and multiple color spaces. Used in publishing, prepress, and archiving workflows.
GIF is widely supported for simple animations and graphics. BMP is Windows' native uncompressed format, required by some legacy software. Both are still used in specific contexts.
When Should You Convert Image Formats?
Web Performance
Convert JPG and PNG images to WebP or AVIF to reduce page load times. Smaller images mean faster websites and better Google PageSpeed scores. WebP is 35% smaller than JPG — switching can dramatically improve Core Web Vitals.
Print & Publishing
Convert images to TIFF for professional print workflows. TIFF preserves maximum quality and color depth required by print production software like Adobe InDesign and Photoshop.
Sharing & Compatibility
Convert WebP or AVIF to JPG when you need maximum compatibility. Not all apps, email clients, and older devices support modern formats. JPG works everywhere.
Design & Editing
Convert photos to PNG when you need to add transparency or edit without quality loss. PNG's lossless format is ideal for graphic design assets, UI elements, and layered compositions.
Storage & Archiving
Convert BMP or TIFF files to PNG or WebP to dramatically reduce storage space without losing quality. A BMP file converted to WebP can be up to 95% smaller.
Legacy Software
Convert modern formats to BMP or TIFF for compatibility with older Windows software, industrial hardware, and specialized applications that only accept specific formats.
Frequently Asked Questions
Is ImageConvertFree really free?
Yes — completely free with no registration, no watermarks, no file size limits, and no daily conversion caps. The tool is supported by non-intrusive ads.
Are my images safe and private?
Your images never leave your device. All conversion happens locally in your browser using the HTML5 Canvas API. No image data is ever uploaded, stored, or accessed by our servers.
Which format should I use for my website?
WebP is the best choice for most websites — 25–35% smaller than JPG/PNG with full browser support. For maximum compression on modern browsers, use AVIF (up to 50% smaller than JPG).
What's the difference between JPG and PNG?
JPG uses lossy compression — great for photos, smaller files, but some quality loss. PNG is lossless — preserves every pixel, supports transparency, but larger files. Use JPG for photos and PNG for logos and graphics.
Does converting reduce image quality?
Only if you use lossy compression (JPG, WebP lossy, AVIF). Selecting Lossless quality preserves every pixel. Converting from lossy to lossless doesn't recover lost data, but it won't lose any more.
Can I convert multiple images at once?
Yes — drag and drop up to 20 images at once. After conversion, download them individually or click Download All as ZIP to get everything in one archive.
Is WebP or AVIF better for websites?
AVIF offers better compression (up to 50% smaller than JPG vs WebP's 35%), but WebP has slightly broader compatibility with older browsers. Both are excellent choices for modern web use.
Can I resize images while converting?
Yes — enable the Resize toggle on any converter page. Choose By Width, By Height (each image keeps its own aspect ratio), or Custom (exact dimensions). You can also use preset sizes like 1920px, 1280px, or 1080h.
