Attach your JPG 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.
Open ToolGPT and press the + button beside the message box, or drop one or more images into the chat. No account is needed to start.
Type “Convert these to WEBP”, or tap WEBP on the card ToolGPT shows. For JPEG and WEBP you can set the quality too.
Each image comes back as its own WEBP with a download button. Your originals are not changed.
Websites load faster with WEBP, which usually makes photos noticeably smaller than JPG at a similar look. ToolGPT shows a size estimate for your own photos before converting, and you can set the quality anywhere from 1 to 100.
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.
JPG, also written JPEG, is the standard format for photographs, used by cameras, phones and almost every website. It compresses images with loss, so photos stay small while still looking natural. It has no transparency, and strong compression or repeated saving adds blocky artifacts, especially around text and sharp edges.
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.
Yes. Attach them together and ask once. Every image gets the same settings and its own result.
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.
No. ToolGPT converts them in your browser.
