PNG to WebP Converter

This free PNG to WebP converter turns PNG images into modern WebP format, which is typically far smaller at similar quality — great for faster web pages. WebP preserves transparency like PNG, and every result is drawn on a checkerboard so you can see the transparent areas. Adjust the quality, optionally resize (scale by percentage or clamp the longest edge), then download each file — or grab everything at once as a single ZIP.

Unlike single-file converters, this tool handles a whole batchat once: drop in dozens of PNGs, tune quality once, and every image re-encodes live. Each card shows the output dimensions and the exact before → after size with the percentage saved, plus a running total across the batch so you can see how much you've shaved off. You can add more files to an in-progress batch, remove individual images, or clear everything.

Encoding uses the native canvas encoder, there are no file-count or size limits beyond your device's memory, and there's no sign-up or watermark. If your browser can't encode WebP (rare on modern browsers), you'll get a clear message instead of a silent failure.
