What is Image Converter?
Each image format suits a different job. PNG keeps sharp edges and transparency, JPEG produces small files for photos, and WebP is usually smaller than both at similar quality. This converter re-encodes your images into the format you choose with the browser's own canvas encoder.
Conversion runs entirely on your device. Files are never uploaded, so private photos and documents stay with you, and there is no daily limit or sign-up.
How to use
- Drop one or more images, or click to choose them.
- Pick the output format (PNG, JPEG or WebP) and adjust the quality if it applies.
- Check the size change for each file, then download the converted images.
Frequently asked questions
Which format should I choose?
Use PNG for screenshots, logos and anything that needs transparency. Use JPEG for photos when you need maximum compatibility. Use WebP for the smallest files when your audience uses modern browsers.
Why does a transparent PNG turn white when converted to JPEG?
JPEG has no transparency channel, so transparent pixels are filled with white. Convert to PNG or WebP if you need to keep the transparent background.
Does an animated GIF stay animated?
No. The converter reads the first frame only, so the output is a single still image.
Why won't some files open?
Browsers decode only common web image formats. HEIC photos from iPhones often fail in Chrome and Firefox; export them as JPEG from the Photos app first.
