Converting from PNG to JPG reduces file size dramatically for photos without transparency. Converting from JPG to PNG is useful when you need lossless quality or transparency support. Modern formats like WebP and AVIF offer superior compression while maintaining visual quality, making them ideal for web performance. GIF and BMP conversions are less common but still supported for legacy systems or specific use cases.
This tool supports PNG (lossless, transparency-friendly), JPG (lossy, best for photos), WebP (modern, efficient compression), AVIF (cutting-edge, excellent quality-to-size ratio), GIF (legacy, animation support), and BMP (uncompressed, large file sizes). HEIC/HEIF photos from iPhones and modern Android devices can be opened and converted to any of these. JPG, WebP, and AVIF allow quality adjustment from 1% to 100%, giving you full control over compression.
LeanTul's image tools also include Image Resize, Image Rotate, and Image Merge for quick editing workflows.
Are my images uploaded when I convert them?
No. All conversions happen entirely in your browser using JavaScript and the Canvas API. Your images never leave your device, ensuring full privacy and security.
What image formats can I convert between?
You can convert images to and from PNG, JPG, WebP, AVIF, GIF, and BMP formats, and open HEIC/HEIF photos (the iPhone default) as input. The tool supports all modern image formats commonly used for web and print.
Can I convert HEIC photos from an iPhone to JPG?
Yes. Open a .heic or .heif file and choose JPG (or PNG, WebP, AVIF). The HEIC decoder loads on demand and runs in your browser, so the photo is never uploaded. It works in Chrome, Firefox, Edge, and Safari.
Can I control the quality when converting to JPG or WebP?
Yes. When converting to JPG, WebP, or AVIF, a quality slider appears allowing you to adjust compression from 1% to 100%. Higher quality means larger file sizes but better image fidelity.
Why would I convert an image and reduce its quality?
Reducing quality during conversion shrinks file size significantly, which is useful for faster website loading, email attachments, or saving storage space. Often a quality setting of 80-90% produces visually similar results with much smaller files.
