Why convert a PNG to WEBP?
WEBP supports transparency just like PNG does, but compresses it far more efficiently — so you keep the see-through background while cutting the file size down, often significantly.
That makes it the better default for anything going on a website: logos, icons, and graphics with transparent backgrounds load faster as WEBP without losing what made PNG the right format in the first place.
Not sure which format to use?
Here's what each format is actually for. Use "I have this" to set it as your Input, or "I need this" to set it as your Output.
JPG
- Best for everyday photos.
- Small files, great compatibility.
PNG
- Best for logos, screenshots, and transparency.
- Lossless quality.
WEBP
- Best for websites.
- Smaller files with transparency support.
HEIC
- iPhone's default photo format — accepted as input.
- Convert it to JPG, PNG, or WEBP for wider compatibility.
- Best for sharing multiple images as one document.
- You can also merge them with our Combine tool.
