Convert Images Between PNG, JPG, WEBP, ICO, And TIFF

This guide maps to the tool directly so you can apply each step while reading.

Pick format by use case, not habit #

Use PNG when transparency is required, JPG for photos where small size matters, WEBP for modern web delivery, ICO for icons, and TIFF for archive or print workflows.

If a destination system rejects a file, convert to the simplest accepted format first and confirm dimensions before re-uploading.

Control quality and dimensions #

Quality settings matter most for JPG and WEBP. Start high, then reduce only enough to meet size limits.

Resize during conversion if your output slot has strict dimensions. This avoids scaling artifacts in downstream platforms.

Transparency and color behavior #

If you convert transparent PNG to JPG, transparent regions are flattened. Use PNG or WEBP when alpha is required.

For icon outputs, generate clear square source assets before converting to ICO for better visual results in app launchers.

Build a repeatable conversion pipeline #

Save format decisions per channel: website assets, app icons, document embeds, and print exports should have separate presets.

Once converted, run compression only when needed. Double optimization can reduce quality without meaningful size gains.
