How to Convert PNG to WebP (Step by Step)

Opening a file on the wrong device often starts with the wrong format. This guide explains how to convert PNG files to WebP in your browser — handy for HEIC iPhone shots, WebP exports, and older JPG workflows.

What you'll need

• The source image (HEIC, PNG, WebP, TIFF, and more)
• An idea of your output format (JPG for photos, PNG for transparency)
• A browser tab — no plugins required

Step 1: Open the converter

Visit imageresize.cc/convert-png-to-webp — the Convert tab opens with WebP pre-selected. Bookmark the page if you use this workflow often.

Step 2: Upload your file

Add your PNG image. HEIC and TIFF files are handled automatically even if your browser cannot preview them natively. If the preview looks wrong, check you picked the correct source file.

Step 3: Adjust quality

For WebP output, set the quality slider. Higher values preserve detail; lower values shrink file size.

Step 4: Apply and download

Click Apply, preview the result, then Download or Share your converted file.

Practical tip

Converting to WebP can significantly reduce file size for web use while keeping good visual quality.
