Image Format Converter

Which format should I use?

• PNG — best for images with transparency or sharp edges (logos, screenshots, graphics)
• JPEG — best for photos; smaller files, no transparency support
• WebP — usually smaller than both at similar quality, with transparency support; supported by all modern browsers

A note on transparency

Converting a transparent PNG to JPEG fills the transparent areas with white, since JPEG has no transparency channel. Converting to WebP preserves transparency.

How it works

The image is drawn onto a canvas at its original width and height and exported in the format you pick. JPEG and WebP are saved at 92% quality; PNG is lossless. The image is converted as soon as you load it, using WebP by default, and choosing another format converts it again.

What to expect

• Going from JPEG to PNG usually makes the file larger without improving quality, because detail already lost can't be restored.
• Converting one lossy format to another, such as JPEG to WebP, compresses again and can add a little extra softness.
• Camera metadata such as GPS and capture time is not carried into the new file.
• An animated GIF becomes a single still frame.
• Only PNG, JPEG and WebP are offered as outputs. Whether an input opens depends on your browser, and HEIC photos in particular may not load in every browser.

Conversion runs on your device, so the image is never uploaded.
