Convert 1000+ JPG Files to WebP

Drop in your JPG files and get WebP files back. Everything runs in your browser: nothing is uploaded, there is no file size limit and you do not need an account.

Accepts: images (PNG, JPG, WebP, GIF, BMP, SVG, ICO, AVIF, HEIC), PDF, Word (.docx), Markdown, HTML, TXT, spreadsheets (XLSX, XLS, ODS, CSV, TSV), JSON, XML, YAML, and video (MP4, MOV, WebM, MKV) or audio. Video can become GIF (first 15 seconds), WebM or MP4 (recorded in real time, so it takes as long as the video), a still image, or just the audio. Mixed batches are fine.

How to convert JPG to WebP

  1. Drag your JPG files into the box above, or click it to choose them.
  2. WebP is already selected as the output format.
  3. Press Convert Files, then Download All. Several results arrive as one ZIP.

Why convert JPG to WebP?

WebP photos are usually noticeably smaller than JPG at similar quality, which speeds up websites and saves storage.

JPG is the most widely supported photo format: small files, but no transparency and some quality loss. WebP is a modern image format with much smaller files than PNG or JPG, but some older apps, editors and upload forms still reject it.

Your files never leave your device

Most online converters upload your files to a server. This one does the work inside your browser, so your JPG files stay on your computer or phone. That also means no waiting for uploads and no cap on file size.

Good to know

Saving WebP needs a browser that can encode it (Chrome, Edge and Firefox can); Safari may refuse.

Converted images are re-encoded from scratch, so metadata such as camera details and GPS location is not carried over. JPG and WebP output use quality 92.

Frequently asked questions

Are my JPG files uploaded to a server?

No. The conversion runs inside your browser on your own device. Your files are not sent to us or anyone else. Besides loading this page and, for some formats, a small helper library, nothing is downloaded or uploaded while you convert, and you can confirm that in your browser's developer tools (Network tab).

Is there a limit on file size or number of files?

We do not set one. The only limit is your device's memory, so for very large batches (thousands of files, or very big videos) work in several groups.

Do I need to sign up, install anything or accept a watermark?

No. There is no account, no install and no watermark. Open the page, add your files and download the results.

How do I convert many JPG files at once?

Drag them all in together or pick them in the file chooser. They are converted one after another, and Download All saves the results as one ZIP (a single result downloads directly).

Are there any limitations converting JPG to WebP?

Saving WebP needs a browser that can encode it (Chrome, Edge and Firefox can); Safari may refuse. Converted images are re-encoded from scratch, so metadata such as camera details and GPS location is not carried over. JPG and WebP output use quality 92.

Your files stay on your device

All conversions happen inside your browser. The files you add are never uploaded to our servers, and we cannot see them, store them or share them. Closing or reloading the page discards them.

What we collect

We do not ask for accounts, names or email addresses, and we do not collect personal information ourselves. The only thing saved in your browser is your chosen theme (white, dark grey or black), kept in local storage so it is remembered next time. You can clear it in your browser settings.

Third-party services

Advertising. The ad at the top of the page is provided by A-ADS, and other ad networks may be added. Ad providers can receive technical information such as your IP address and browser details, and may use cookies or similar technology. See each provider's own privacy policy for details.

Hosting and libraries. This site is served by a hosting provider, which receives standard server logs such as your IP address. When you use a conversion that needs a helper library, your browser downloads it from cdnjs (Cloudflare) or jsDelivr, which can see your IP address as part of that request.

Tips

The crypto addresses in the footer are public. Tips are sent through the Solana and Base blockchains, which are public. We do not collect any information about you when you send one.

Children

This site is not directed at children under 13, and we do not knowingly collect information from them.

Changes

We may update this policy and will change the date above when we do.
