How do I convert a JPG to WebP?

Add the JPG above, set the quality and click “Convert to WebP”. The WebP downloads as a new file and your original JPG stays untouched. You can see the file size, so it is easy to judge whether the saving is worth it for that picture.

The main audience is anyone running a site: a shop with product photos, a blog with big headers, a portfolio full of pictures. Swapping them for WebP is one of the simplest ways to make pages feel quicker.

Tip: Keep your original JPGs. If a platform or a visitor’s software cannot open WebP, you will want the JPG to fall back on.

Why use WebP for website images?

Web pages are mostly pictures, and pictures are mostly bytes. Trimming each image trims the total the visitor must download, which matters most on slower connections and for people with limited data. Faster loading also tends to make a site feel more professional and keeps visitors from leaving.

WebP was designed for exactly this job. For many photographs it reaches a similar look in fewer bytes than JPG, and it still supports transparency should you later need a logo in the same format.

When should I stay with JPG?

  • Sending to people. Email attachments, chat and printing shops are safest with JPG.
  • Forms and portals. Many application systems accept JPG or PNG only.
  • Older software. Some office programs cannot open WebP.
  • Archiving originals. Keep the JPG as your master, and make WebP copies for publishing.

If the image already needs to meet a size cap, like 200 KB, convert and then use Compress image for the final push.

Is it safe to convert JPG to WebP online?

Yes. The page loads online, but the converting runs in your own browser. The JPG is read, encoded as WebP and returned on your device, and nothing about the file, its name or its size is sent to a server. Useful when the pictures are product photos you have not launched yet.

Once you have opened the tool, it keeps working without a connection. Watch your browser’s network tab while you convert if you would like to confirm that no file leaves your device.

Questions answered

Is WebP really smaller than JPG?

Usually, at a similar look. The saving varies with the picture, so check the size shown for yours. Very small or already well compressed JPGs may gain little.

Will every website and app accept WebP?

Modern browsers show it, but some forms, older programs and printers do not. Use WebP for your own site and keep a JPG copy for sending to other people.

What quality should I choose for a website?

A middling to high setting keeps photos crisp while still saving space. Compare the preview with the original, since detailed pictures show compression first.

Does converting JPG to WebP lose quality?

Both formats are lossy, so a little detail can change, but at sensible settings it is hard to see. Convert from your best original rather than from a copy that was saved many times.

Should I resize the image as well?

If the photo is far bigger than it will ever display, resizing it with Resize image gives a larger saving than changing format alone. Do both for the lightest result.

Is it safe to convert JPG to WebP online?
