Why convert PNG to WEBP?
Screenshots, logos and web graphics saved as PNG can often be made much smaller as WEBP, which helps pages load faster. WEBP supports transparency, so cut-out images keep their see-through background.
Convert PNG images to WEBP
Attach your PNG pictures and ask for WEBP. Before anything is converted, ToolGPT can show what each format would do to your own files, with a size estimate, so you can see the trade-off and tap the one you want.

How ToolGPT converts PNG to WEBP
The conversion runs in your browser: each image is decoded and written again on your device, not uploaded to a server. Every image becomes a new file.
Formats differ in what they keep. JPEG cannot store transparency, PNG keeps every pixel exactly and is often larger for photos, and WEBP usually gives the smallest file for the same look.
About PNG
PNG is a lossless image format widely used for screenshots, logos, icons and graphics that contain text. It keeps every pixel exact and supports transparent backgrounds. For photographs, though, a PNG is usually much larger than a JPG of the same picture.
About WEBP
WEBP is an image format developed by Google that can be lossy or lossless and supports transparency and animation. Websites use it because it makes images noticeably smaller than JPG or PNG at a similar quality. Some older programs, photo editors and upload forms still do not accept WEBP files.
Frequently asked questions
Can I convert many images at once?
Yes. Attach them together and ask once. Every image gets the same settings and its own result.
Will the WEBP be smaller than the PNG?
It depends on the two formats and the picture. ToolGPT can show a size estimate for your own files before converting. Converting a photo to PNG usually makes it larger.
Are my images uploaded?
No. ToolGPT converts them in your browser.
