Choose Files or Drag & Drop Here
Supports PNG, JPG, WEBP, BMP, GIF, AVIF
Simple & Convenient
Choose images and convert them directly in your browser. Processing time depends on your device and file size.
Processed in Your Browser
The converter is designed to process selected image data locally in your browser instead of uploading image content to our application server.
Flexible Format Support
Choose JPG, PNG, WEBP, BMP, AVIF, or ICO as the output format. Results can vary by format and browser.
How to use
The converter reads PNG, JPG, WebP, BMP, GIF and AVIF images and saves them as JPG, PNG, WebP, BMP, AVIF or ICO. Each image is drawn on a canvas in your browser and saved again in the new format, so the image itself is not sent to a LeedyBox server.
- Click the drop zone or drag images onto it. You can add several images at once.
- Each image has its own format menu, set to JPG at first. Choose a format for each image, or use "Set All Formats To..." to change them all. ICO files are scaled to fit within 256 × 256 pixels.
- Remove an image with its × button, or click "Clear All" to start again.
- Click "Convert & Download". A single image is saved as name_converted.jpg (or the extension of the format you chose); several images are saved together in leedybox_converted_images.zip.
- Open the converted files before you delete the originals, and check transparency, colours and size.
Frequently asked questions
Are my image files uploaded to or stored on the server?
No. The images are converted in your browser and are not sent to a LeedyBox server. The page itself still loads scripts, analytics and advertising from other services, as described in the Privacy Policy.
Are there any fees or daily conversion limits?
The converter is currently available free of charge, and the page does not impose a daily conversion count limit. Actual performance and practical limits can depend on your device memory, browser, and file sizes. For smoother operation, consider converting smaller batches when working with many large images.
What happens to transparent backgrounds when converting PNG to JPG?
JPG does not support transparency. When the converter creates a JPG or BMP file, transparent areas are filled with a white background.
Can I convert HEIC photos from an iPhone?
Only in a browser that can open HEIC itself, such as Safari on a Mac or iPhone; other browsers show a message instead. You can also export or share the photo as a JPG on the phone first.
Why can't I select AVIF?
Creating AVIF files depends on the image encoder built into your browser. When your browser cannot create AVIF, the option is marked as not supported; WebP is a widely supported choice for small files.
What happens to animated GIFs, photo metadata and quality?
Only one frame of an animated GIF is converted, so the result is a still image. EXIF details such as the camera, date and GPS location are not copied, because each image is redrawn before it is saved. JPG, WebP and AVIF files are saved at quality 92 of 100; use the Image Compressor tool when you need smaller files.
