How to use the image converter
- 1 Drop your images on the box, or click browse to choose them. You can add many at once.
- 2 Choose the format to convert to: JPG, PNG or WebP, and the quality.
- 3 Press Convert. One image downloads directly; several come in a ZIP file.
- 4 Check the new size and file size shown under each image.
Choosing an image format
JPG is best for photos, PNG for graphics, screenshots and transparency, and WebP for the smallest web images. For one specific conversion, such as JPG to PNG or HEIC to PNG, the dedicated tools have tailored settings.
- Avoid converting the same image back and forth between lossy formats.
- PNG to JPG fills transparency with white or black.
- Check the file size after converting; then compress if needed.

Frequently asked questions
Which format should I choose?
JPG for photos to share, PNG for logos, screenshots and anything with transparency, and WebP for the smallest files on websites.
Can it convert GIF animations?
It converts the first frame of a GIF to a still image. Animation is not kept.
What happens to transparency in JPG?
JPG cannot store transparency, so transparent areas become white or black, whichever you choose.
Can I convert to HEIC or AVIF?
Not at the moment. Browsers can read these formats but cannot reliably save them, so the outputs are JPG, PNG and WebP.
Does converting reduce quality?
Converting to PNG adds no loss. JPG and WebP use compression; the High setting keeps the difference hard to see.
Are file names kept?
Yes. Each file keeps its name with the new extension.
Is BMP supported?
Yes, BMP files can be converted to JPG, PNG or WebP, which are much smaller.
Why convert images at all?
Different places expect different formats. Forms often want JPG, designers want PNG with transparency, and websites benefit from WebP. Converting lets one picture work everywhere.
Can I convert screenshots to JPG?
Yes, but screenshots with text often look sharper as PNG. Convert to JPG only when you need a smaller file.
Is there a file size limit?
There is no fixed limit, because the work happens on your device. Very large images, above about fifty megapixels, may be slow or fail on phones with little memory.
How this tool works. These image tools run entirely in your browser using the Canvas API built into every modern browser, the open-source libheif decoder for iPhone HEIC photos and Tesseract, a widely used open-source OCR engine, for reading text. Each tool is tested with real phone photos, screenshots and scans before it goes live, and nothing you open is sent to a server.
