Convert Images Online Easily – Free Image Converter by PooreTools
This free image converter lets you change supported image files between common formats directly in your browser. Upload an image, choose the output format, process locally, and download the result. Processing is designed to stay on your device so your files are not uploaded to MooneyCourses for conversion.
How to Convert an Image
- Select an image – Click the upload area or drag and drop a file (up to 10 MB recommended).
- Choose an output format – Select JPG, PNG, WebP, AVIF or PDF (and high-quality variants where available).
- Convert and download – Click Convert Image, then download the generated file.
Supported Formats
- JPG / JPEG – Photographs and general sharing; wide compatibility.
- PNG – Graphics, icons and images that need transparency or lossless quality.
- WebP – Smaller files for the web while keeping good visual quality.
- AVIF – Modern format with strong compression on supported browsers.
- HEIC – Input support for many iPhone photos; convert to JPG or PNG for broader use.
- PDF – Places the image into a single-page PDF document.
Why Use This Converter?
The tool uses browser APIs such as HTML5 Canvas and client-side libraries (including heic2any for HEIC and jsPDF for PDF). Because conversion runs on your device, it can be fast and private, without relying on a remote conversion server for your file content.
Limitations
- Browser processing – Speed depends on your device CPU and memory.
- File size – About 10 MB is recommended for stable performance.
- Dimensions – Very large images may be scaled down (up to about 4096×4096 px) to avoid browser crashes.
- AVIF export – Requires a browser that supports encoding AVIF; otherwise the tool may fall back to another format.
Frequently Asked Questions
Is this image converter free?

Yes. Upload a JPG and choose WebP as the output format.
Can I convert WebP to JPG?
Yes. Upload WebP and select JPG as the target format.
Can I convert PNG to JPG?
Yes. Transparent areas in PNG are filled with a white background when exporting to JPG.
Can I convert HEIC to JPG?
Yes. Many iPhone HEIC photos can be converted to JPG or PNG for easier viewing on other devices.
Does it work on mobile?

Does converting reduce quality?
Lossy formats (JPG, WebP, AVIF) use compression; quality depends on the option you select. PNG aims for lossless quality. Very large images may be resized for stability.
