Complete guide to image conversion online
Converting images between formats is one of the most common tasks for web developers, designers, marketers, and photographers. Whether you need to convert PNG to JPG to reduce file size, or convert images to WEBP to speed up your website, using a free online image converter saves time and requires no software installation.
Why convert PNG to JPG?
PNG files use lossless compression, which preserves every pixel perfectly — but at the cost of larger file sizes. JPG uses lossy compression optimised for photographs, achieving file sizes 70–90% smaller with minimal visible quality loss. If your PNG doesn't require transparency, converting it to JPG is one of the easiest ways to reduce image file size without losing quality.
Why convert images to WEBP?
WEBP was designed by Google specifically for the web. It combines the best of both JPG (small files for photos) and PNG (transparency support) into a single modern format. Studies show WEBP files are 25–35% smaller than equivalent JPG files at the same perceptual quality. Major search engines including Google reward fast-loading pages with higher rankings, making WEBP conversion a direct SEO improvement.
What is AVIF and should you use it?
AVIF (AV1 Image File Format) is the newest major image format, producing files 50% smaller than JPG and around 20% smaller than WEBP at the same quality. It also supports HDR colour, wide colour gamut, and transparency. Browser support reached around 85% in 2024, with Chrome, Firefox, and Safari all supporting it. For cutting-edge web performance, AVIF is the format of choice.
How to convert multiple images at once
Our batch image converter lets you drop any number of images into the upload area simultaneously. Select your output format, adjust quality if needed, and click Convert. All images are processed in parallel within your browser using the Canvas API — you can download them individually or use "Download All" to get everything at once.
How to convert images to PDF
Select the PDF output format, choose a page size (Fit to image, A4, or US Letter), then upload your images. Multiple images are automatically merged into a single multi-page PDF, one image per page. This is ideal for creating portfolios, document scans, or image-based reports without installing Adobe Acrobat or any other software.
Create a website favicon (.ico)
If you need a favicon.ico file for your website, select the ICO format and upload your logo. The converter will automatically ensure the image is properly sized (up to 256x256) and output a perfectly formatted Windows Icon file that works in all browsers.
Image conversion for SEO: reduce file size, improve rankings
Google's Core Web Vitals include Largest Contentful Paint (LCP) — a metric that measures how fast the main content of your page loads. Large, unoptimized images are the single biggest cause of slow LCP scores. By converting images to WEBP or AVIF and using appropriate quality settings (80–90% is usually ideal), you can reduce image payload by 50–80%, directly improving your PageSpeed score and Google rankings.
